JOHN M. MYERS, ED. "SENECA ADVERTISER." Tiffin (EDWARD), M. D., b. at Carlisle, England, June 19, 1766: emigrated to the U. S. 1786, settling at Charlestown, Va.; became a Methodist preacher, acting also as a physician; married Mary, sister of Gov.

Three of his Sermons, preached in 1817, were published in the Ohio Conference Offering (1851). A thriving city in Northern Ohio bears his name.

Tiflis, government of Russia, bounded N. by the Caucasian Mountains and S. by Asiatic Turkey. Area, 15,613 sq. m. P. 709,259, consisting of Georgians, Armenians, Tartars, and Russians, who belong partly to the Christian, partly to the Mohammedan religion. The surface is mountainous, covered with branches both from the Caucasian an i from the Ararat mountains, several peaks of which rise to 12,000 feet. The soil, of which only a very limited portion is under cultivation, is very fertile in the valleys, and tobacco, cotton, and indigo, wheat and other cereals, grapes, peaches, and all S. European fruits, grow abundantly. Numerous forests of oak, elm, chestnut, and maple yield excellent timber.

Tiflis, town of Russia, capital of the government of Tiflis an i the centre of the whole Russian territory S. of the Caucasian Mountains, on both sides of the Koor, has some manufactures and carries on an active trade with Persia. In its vicinity are naphtha springs, and thermal springs which are much frequented. P. 104,024.

Ti'ger [Gr. riypes], the name, derived through the learned tongues, applied to certain quadrupeds. (1) Primarily and of right only it belongs to the Felis tigris, one of the largest of living Felidæ, about equal in size and superior in strength to the largest lions, and more destructive and far more dangerous to man. It is peculiar in the development of spreading thick, whisker-like hairs on the sides of the head; its tail is elongate and smooth-haired, and the color is a tawny yellow transversely striped with black. It ranges N. into Southern Siberia, and S. as far as Cerlon and the Spice Islands. E. and W. its habitat exten is from Persia to the Pacific. It prefers forests and jungles near river-banks for its abode. It is much dreaded by man, especially in parts of India. The tiger has been frequently induced to hybridize with the lion in captivity. Old tigers sometimes acquire a great fondness for human flesh, and are then called "man-eaters." The hunting of the tiger is a favorite though perilous amusement in Oriental lands. (2) The name is also sometimes applied by hunters to the American JAGUAR (Felis onça), (which see). | (3) It is further transferred in Van Diemen's Land to the striped Thylacinue cynocephalus, a carnivorous marsupial. (See THYLACINIDE.)

Tiger-Beetle, a name given to the species of coleopterous insects of the family Cicindelidæ, on account of their active, bold, and carnivorous nature. They are distinguished VOL. VIII.-2

17

by their large and broad heads, and the very long and formidable falcate jaws, as well as by their long and slender legs. They chiefly affect sunny and sandy places, especially by the shores of streams and lakes. They are unusually swift in their movements, and are therefore difficult to capture. The larvæ is also characterized by large head and formidable jaws. They live mostly concealed in holes near the borders of water, and there lie in wait for their

prey, weaker insects which come near. THEODORE GILL.

Tiger-Cat is a name applied to quite a large number of striped and spotted wild-cats, mostly rather small tropical animals, often arboreal in their habits.

Tiger-Flower, the Tigridia paronia, a superb garden-flower of the order Iridacea. It is a native of Mexico, and is cultivated for its splendid flowers, each of which endures but for a day, a fresh one sometimes following for many days in succession. The flowers are without perfume, but gorgeous in color.

Tighe (MARY Blachford), b. in Dublin, Ireland, in 1773; married in 1793 her cousin, Henry Tighe, of county Wicklow, a member of the Irish Parliament; published in 1805 for private circulation her Psyche, a poem of remarkable excellence, based on the well-known story of Apuleius. D. of consumption at Woodstock, county Kilkenny, Ireland, Mar. 24, 1810. Her Works, which appeared in 1811, have passed through several editions.

Tiglath-Pileser. See AssYRIA, by W. JACOBS, A. M. Tigra'nes the Great, king of Armenia (96–55 B. c.), conquered in his wars with Parthia, Mesopotamia, Assyria proper, and Media Atropatene, and in his wars with the Seleucidæ, Cilicia, Syria, and Phoenicia. But having been involved in war with Rome through his father-in-law, Mithridates the Great, king of Pontus, he was defeated first by Lucullus, who took and sacked his capital, Tigranocerta, and subsequently by Pompey, to whom he had to pay an enormous sum in order to remain in possession of Armenia proper, while Lesser Armenia was given to Dejotarus, and all his foreign conquests either returned to their old masters or were incorporated with the Roman province of Asia. He was succeeded by his son, Artavasdes or Ardavast.

Tigré, province of Abyssinia, between lat. 12° and 16° N. and lon. 37° and 40° E., was formerly an independent state until conquered in 1855 by Theodore. Its capital is Adowa, one of the principal stations on the caravan-route between Massorah and Gondar.

Ti'gris, river of Asiatic Turkey, rises in the mountains of Koordistan, and after a winding but generally southeastern course of about 1000 miles, it joins the Euphrates at Korna, and forms the Shatt-el-Arab, which enters the Persian Gulf after a course of about 100 miles. The principal places on its banks are Diarbekir, Mosul, and Bagdad, and the ruins of Nineveh, Seleucia, Ctesiphon, and Opis. Along its upper course its banks are lined with fine pastures, visited by the nomadic tribes of the neighborhood. From Diarbekir, where it becomes navigable for rafts and small vessels, to Mosul, its banks are highly cultivated; but a few miles below Mosul, and down to Bagdad, almost all vegetation ceases, and the land on both sides of the river becomes a mere desert. From Bagdad to Korna the banks are steep and overgrown with high reeds and brushwood, which form the haunts of lions and other beasts of prey. The average breadth of the Tigris between Mosul and Bagdad is 200 yards, but its depth, velocity, and breadth vary very much according to season. It reaches its greatest height between the middle and last of May, after which it decreases until the middle of June. It is now navigated to some extent by steamboats.

Tikhvin', or Tichvin, town of Russia, government of Novgorod, on the Tikhvinka, which by a canal is connected with the Volga. P. about 5969.

Til'burg, town of the Netherlands, province of North Brabant, is the seat of a great cloth-manufacturing industry. Several thousand persons are engaged in this business, but each family has a house of its own, to which belongs a strip of land for the cultivation of vegetables. Printworks, breweries, and soap-factories are also in operation. P. 28,390.

Tilden, cap. of McMullen co., Tex. (see map of Texas, ref. 7-G, for location of county). P. not in census of 1880. Tilden (SAMUEL JONES), b. in New Lebanon, N. Y., Feb. 9, 1814, pursued his academic studies at Yale College and the University of New York, took the course of law at the latter, and was admitted to the bar in 1841. In the mean time, his rare abilities as a writer and a thinker upon public topics had attracted the attention of his father's neighbor and friend, President Van Buren, of whose policy and administration he became an active and efficient champion. He made for himself

rapidly a conspicuous place in the front ranks of the profession, and amassed by his earnings and a judicious investment of them the largest fortune ever accumulated by any American barrister. During the most laborious period of his professional life he was one of the leaders and most trusted counsellors of the Democratic party. He was a member of the convention for a revision of the constitution of the State in 1846, and again in 1867. He also served two terms in the lower branch of the State legislaturefirst in 1846, and second in 1872. He took a controlling part in the overthrow of the "Tweed Ring," in the establishment of a reformed city government, and by the successful impeachment of one judge and the compulsory resignation of others in the purification of the judiciary. In 1874 he was nominated and chosen governor of the State of New York by a majority of more than 50,000 votes, defeating Gen. Dix, a Republican candidate, who had been elected two years before by a majority of 55,451. The convention which nominated him was the first State convention which took a firm stand against "soft money" and against the bad ambition of a third term," declarations against both of which were inserted at his special instance. His messages were national sensations. He exposed the iniquities of the " Canal Ring" and crushed its sway over the legislative, administrative, and judicial departments of the State. Wasteful and corrupt systems were destroyed, State taxation was reduced nearly or quite one-half, and new remedies for official malversation were enacted. The standard of official life was elevated. The chief executive and administrative trusts of the State were committed to gentlemen eminent not only for personal probity, but for capacity and high ideals of official duty, thus realizing a genuine reform in the civil service. In 1876 he was nominated by the National Democratic Convention for the Presidency without considerable opposition. At the election he received a much larger popular vote than any other candidate, and 184 uncontested electoral votes. Only one additional electoral vote was required for his election, while twenty additional votes were required for the election of the rival candidate. A special tribunal unknown to the Constitution was created by Congress to count the electoral votes. This tribunal refused to admit evidence impeaching the right of the Republican claimants to be considered the lawful electors, and counted for the

Tile [Fr. tuile; Lat. tegula], a flat plate of baked clay, used for roofing, for flooring, and for various ornamental purposes in architecture. The more highly-ornamental varieties are called ENCAUSTIC TILES (which see). The earthenware pipes used in the drainage of land are also called tiles. They are of various patterns and sizes, are extensively manufactured by machinery, and are burned in the same way as bricks.

Tilgh'man (LLOYD), b. in Maryland 1816; was graduated from the U. S. Military Academy July 1, 1836, when commissioned brevet second lieutenant 1st Dragoons, receiving his full commission to that grade July 4; but without service resigned Sept. 30, 1836, to become a civil engineer, and in that capacity was engaged in the construction of railroads in various sections and of works of public improvement in Baltimore. In the war with Mexico he served as volunteer aide to Gen. Twiggs at the battles of Palo Alto and Resaca de la Palma; commanded a volunteer company Oct., 1846; superintended the construction of the defences at Matamoras in June, 1846; and in command of company of light artillery (Maryland and District of Columbia Vols.) 1847-48. Returning to his profession at the close of the war, he was principal assistant engineer of the western division of the Panama R. R. and chief engineer of several Western railroads in the U.S. He became a general in the Confederate army in 1862, and in Feb., 1862, surrendered at Fort Henry, giving himself up rather than abandon his command; exchanged in July, he served afterward in the South-west, and was killed in the battle of Baker's Creek, Miss., May 16, 1863.

Tilghman (TENCH), b. in Talbot co., Md., Mar. 25, 1810; graduated at the U. S. Military Academy in 1832, when appointed brevet second lieutenant 4th Artillery; resigned Nov. 30, 1833. Locating upon the family estate at Oxford, though thenceforward actively engaged otherwise, he devoted his spare time to agricultural pursuits. From 1841 to 1851 was commissioner of State public works, president Talbot Insurance Co. 1846-49, superinAcademy 1847-57, U. S. consul at Turk's Island 1849, tendent of military department of Maryland Military Maryland and Delaware R. R., projected and carried to and same year at Mayaguez: was president (1855-61) of successful completion by him; also U. S. collector of State militia 1837-60, and major-general 1860-61, when customs at Oxford 1857-61; was brigadier-general of he entered the service of the Southern Confederacy. For many years he was president of the Society of the Cincinnati of Maryland, and treasurer-general of the Society of the U.S. D. at Baltimore Dec. 22, 1874.

Tilghman (WILLIAM), LL.D., b. in Talbot co., Md., Aug. 12, 1756, son of James, secretary of the proprietary land-office; removed to Philadelphia in childhood; studied law under Benjamin Chew; practised at the Maryland bar 1783-93, and was a member of the legislature several years; was chief-justice of the U. S. circuit court 1801-02; became president of the court of common pleas July, 1805, and chief-justice of the supreme court of Pennsylvania Feb., 1806; was president of the American Philosophical Society 1824, and published several occasional addresses. D. at Philadelphia Apr. 30, 1827.

Tilghman's Sand-Blast. See SAND-BLAST, by G. F. BARKER, M. D.

Republican candidate twelve votes deliberately certified by the governors of Louisiana and Florida on the fraudulent returns of the returning boards of those States. It counted among the votes from Louisiana three votes upon certificates one set of which was irregular and illegal, and the other set, intended to repair this irregularity and illegality, was forged. It counted nine votes of persons disqualified from being electors by the Constitution of the Ú. S. by reason of their holding Federal offices. By contradictory rulings upon the same questions arising in different cases, and by a strictly partisan vote, the Commission decided in favor of the Republican electors in every contested case, and certified to the election of Rutherford B. Hayes, the Republican candidate for the Presidency. Impressed with the conviction that Mr. Tilden had been lawfully elected to the Presidency, the Democratic party continued to regard him as its candidate for the succeeding election, in 1880. Before the meeting of the convention for the nomination of the candidates at that election, Mr. Tilden's health-for the benefit of which Tilia'ceæ [from Tilia, one of the genera], a natural he passed the summer of 1877 in Europe-had become so order of exogenous trees, shrubs, and herbs, mostly tropprecarious that he felt unwilling to assume the burdens of ical, and allied to Malvacea. The well-known basswood the chief magistracy, and in a letter to the New York and linden trees belong to this order, as do the jute-plant delegates to the convention of 1880 formally withdrew and a number of timber and fruit trees of tropical refrom public life. Notwithstanding this letter and his ab-gions. The lime or the linden tree, the well-known Eurostention from all active interference in public affairs, and notwithstanding the repeated protestations of his most intimate friends that he would not listen to any proposals, which contemplated his return to official life, it seemed to be the determination of his party to renominate him for the Presidency in 1884, public opinion refusing to concentrate upon any other candidate. Most of the States had gone so far as to instruct their delegates to vote for his renomination. To avoid the confusion that might result from permitting delegates to be elected under the delusive impression that he might yield to such a national manifestation as seemed to be impending, Mr. Tilden addressed another letter to the chairman of the Democratic State committee on the 10th of June, 1884, setting forth anew his reasons and unalterable determination not to return to public life. Mr. Tilden spends most of his time at "Graystone," his charming country home on the banks of the Hudson, indulging his literary and rural tastes so far as his health will permit, and occasionally sharing with those who enjoy his confidence the benefits of his ample stores of wisdom and experience. (See his Writings and Speeches, 1885.)

pean representative of the order, yields a light and useful timber, and its bast is invaluable from its fibrous character. The most important fibrous plants of the order, however, are the species of Corchorus, which yield jute. A few species are found in the temperate parts of the northern hemisphere, but the most useful species belong to the tropical region.

Tilland'sia [named by Linnæus in honor of Dr. Elias Tillands, a Finnish botanist], a genus of epiphytic airplants of the order Bromeliaceae. There are many species, eight of which are natives of the Southern U. S. Of these, T. sneoides, the long or Spanish moss (so called), is the best known. It is abundant in the more humid districts of the South, where it hangs in long festoons from the trees. Its central fibre is extensively used in stuffing mattresses. The plant is used in making an ointment asserted to be a cure for hæmorrhoids, and in winter it is eaten by

Tillinghast (JOSEPH LEONARD), b. at Taunton, Mass., in 1791; graduated at Brown University 1819; became a lawyer at Providence; was many years a member of the State assembly, and often Speaker of that body; was chiefly instrumental in promoting improvements in the judiciary and common-school systems, and was a member of Congress 1837-43. D. at Providence, R. I., Dec. 30, 1844. Author of An Oration on Gen. Greene (1813), A Eulogy on Adams and Jefferson (1826), and other published speeches on political subjects.

Tillman (SAMUEL D.), A. M., LL.D. See APPENDIX. Tilloch (ALEXANDER), LL.D., b. in Glasgow Feb. 28, 1739; was a practical mechanic, and in 1781 conceived the ides of the production of stereotype plates for printing, and for that purpose entered into partnership with Mr. Foulis, a noted printer in Glasgow, and patents for his invention were taken out. His father was a tobacconist, and for a short time he was engaged with his brothers in that business; but he soon returned to printing, and in 1787 went to London, where he purchased The Star, an evening newspaper, which he conducted for more than thirty years. In 1790 he formed a plan for producing bank-notes which could not be counterfeited, but it was not carried into effect. In 1797 he established the Philosophical Magazine, which he edited with great success, an i just before his death commenced the publication of the Mechanie's Oracle, a weekly journal. He was a minister of the sect known as Sandemanians, devoted much attention to the study of the prophecies, and published a volume of Dissertations introductory to the Study of the Apocalypse (1823). D. at Islington Jan. 26, 1825.

tinct. The feet were plantigrade, apparently fitted for digging, and each had five toes. There was a well-marked third trochanter on the femur, and the tibia and fibula were distinct. The best-known species (T. fodiens, Marsh) was about two-thirds the size of a tapir. The first known remains of this order were found in Monmouth co., N. J., and described under the name Anchippodus riparius by Dr. Leidy. This genus, and even species, is now regarded as identical with Trogosus castoridens of the same author, from the Eocene of Wyoming. It is easily distinguished from Tillotherium by the presence of a small pair of incisors in the lower jaw between the large scalpriform ones. The systematic relations of these genera were not known until the discovery of Tillotherium. A second family of this order is represented by Stylinodon, in which the molars are rootless, subquadrate in transverse section, and faced with enamel within and without. S. mirus, Marsh, was about as large as a capybara.

Tillotson (Joux), D. D., b. at Sowerby, Yorkshire, in 1630; was educated at Clare Hall, Cambridge, where he was made a fellow in 1651. He was originally a rigid Puritan, and in 1657 became tutor in the family of Cromwell's attorney-general, but at the Restoration went over to the Established Church, in which he took orders, and became in succession curate of Cheshunt, rector of Keddington, preacher at Lincoln's Inn, dean of Canterbury, prebend of St. Paul's, and finally, in 1691, archbishop of Canterbury, having in the mean while served as clerk of the closet to William III. and as member of the commission appointed in 1689 to revise the English liturgy. took an active part in measures in opposition to popery, opposed the declaration of Charles II. in favor of liberty of conscience, and was an earnest advocate of the exclusion of the duke of York from the succession. He ranks among the foremost of English preachers; published during his lifetime several volumes of sermons, and left many more in manuscript, and for the copyright of these his widow received 2500 guineas. Several editions of his Sermons, in 12 and 14 volumes, were published. His complete works have been published (3 vols. fol., 1707-12, and 10 vols. 8vo, 1820), and many of his sermons have been translated into French and German. D. in London Nov. 22, 1694.

Tilly, von (JOHANN TSERCLAES), COUNT, b. in the castle of Tilly, near Gemblours, province of Brabant, Belgium, in Feb., 1559; was destined for the Church, being a younger

son, and educated by the Jesuits, but preferred the military profession; served under Farnese in the Netherlands, and under Duke Philip Emanuel of Lorraine in Hungary, and was in 1610 appointed field-marshal by Duke Maximilian of Bavaria.

When the Thirty Years' war broke out, he

was made commander-in-chief of the army of the Holy League; suppressed the insurrection in Bohemia after the battle of Prague, Nov. 8, 1620; conquered the Palatinate; defeated Christian IV. at Lutter-am-Barenberg Aug. 27,

1626; was made commander-in-chief also of the Austrian army after the dismissal of Wallenstein in 1630; stormed Magdeburg May 20, 1630, but was utterly defeated by Gustavus Adolphus at Breitenfeld, Sept. 17, 1631, and again on the Lech, Apr. 15, 1632, in which battle he was mortally D. at Ingolstadt Apr. 30, 1632.

Tillodon'tia [Gr. riddew, to tear," and odous, "tooth"], an extinct group of Tertiary mammals, now regarded as forming a distinct order, possessing characters intermediate between carnivores, rodents, and ungulates. In Tillotherium, the typical and best-known genus, the skull resembles in shape that of the bear. It is expanded by aircavities in the frontal region. The orbits are confluent with the large temporal fossæ, which are separated at the Tilt Cove, port of entry on White Bay, Newfoundmid lle line of the skull by an obtuse sagittal crest.

The anterior incisors both above and below are large, curved, scalpriform, and faced in front with enamel. They grow from persistent pulps, and strongly resemble the corresponding teeth of rodents. The canines are quite small. The upper molars are peculiar, and the lower are of the palæotherium type. The braincavity is small. As in most if not all Eocene mammals, the hemispheres were small, and extended but slightly over the cerebellum or over the olfactory lobes. The latter were large and projected well forward. The hemispheres were evidently somewhat convoluted. The cerebellar fossa is large, expanded transversely, and extends above the cerebral cavity. The vertebræ resemble those of some carnivores: the cervicals were short, the lumbars quite large. The radius and ulna were separate and of nearly equal size. The scaphoid and lunar bones were dis

D. near Wilmington May 14, 1822.

Time [Sax. tima] has been characterized as that wherein there is room for events to happen, as in space there is room for things to be placed. "For times and spaces," says Sir Isaac Newton, "are, as it were, the places as well of themselves as of all other things. All things are placed in time as to order of succession, and in space as to order of situation." (Principia, Scholium to Def. vii.) So space and duration (out of which latter time is parcelled out) are to be regarded, in accordance with all experience, as existwhen, and not where, one part or portion of duration ends and another begins, but which does not occupy any portion of duration (does not last at all), such a limit is an instant. It differs from a moment, which is itself a small but indefinite portion of duration. (The busy and hurried man says, "Wait a moment, and I will attend to you.") The analogy, and yet contrast, in this case being thus perfect, it is not strange that an instant should be designated as "a point of time." The instant is that which marks the present, the veritable now; which thus does not last, does not endure. It seems to be in consistency with this that some of the ancient languages have no present tense.

Tilton (THEODORE), b. in New York Oct. 2, 1835; was educated at the New York Free Academy; entered upon journalism at an early age, and in 1856 was employed upon the New York Independent, a weekly religious journaling relations of things actual. The limit which occurs edited by Rev. Henry Ward Beecher; married Elizabeth Richards, himself and his wife becoming active members of Plymouth church, Brooklyn, of which Mr. Beecher was pastor. Mr. Beecher resigning the editorship of the Independent in 1863, was succeeded by Mr. Tilton, who in 1871 also became editor of the Brooklyn Union, a daily newspaper, both being owned by Mr. Henry C. Bowen. In 1872, in consequence of some disputes, his connection with these journals was discontinued, and he established The Golden Age, a weekly journal, which he conducted till 1874. In that year he brought suit against Mr. Beecher, whom he charged with criminal intimacy with his wife, claiming damages of $100,000. The suit lasted six months, and the jury were unable to agree upon a verdict, nine being for the defendant and three for the plaintiff. He was a popular public lecturer, and has published-The American Board and Slavery (1860), Memorial of Mrs. Browning (1862), The Fly (1865), Golden-Haired Gertrude (1865), The Tico Hungry Kittens (1865), The King's Ring (1866), The True Church (1867), The Sexton's Tale, and other Poems (1867), Sanctum Sanctorum, or Proof-Sheets from an Editor's Table (1871), Life of Victoria C. Woodhull (1871), and TempestTossed, a novel (1875).

Timbuc'too, town of Soodan, Central Africa, on a branch of the Niger, near the desert of Sahara, in lat. 18° 4' N., lon. 1° 45' W. It is in an unhealthy and unproductive district; provisions have to be brought to it from distant places. But for the traffic between Northern and Central Africa it is of great importance, and although it has repeatedly suffered severely from being conquered and sacked by the Moors and by neighboring tribes, it has always risen again, and is still increasing. Dates, European manufactures, firearms, gunpowder, tobacco, and paper are brought here through Sahara, and exchanged for gums, ostrich-feathers, gold-dust, and palm oil. The worst hindrance to a rapid development of its commerce is, at present, the rivalry and jealousy between the English and French merchants. The town is poorly built; it consists mainly of mud huts, and contains few buildings worth noticing. It is surrounded with walls, but the walls are in bad repair; it has no manufactures. Its inhabitants, numbering about 13,000, are indigenous negroes, but mixed with them are Tuariks, Foollahs, Bambarras, Mandingoes, Arabs, and representatives of the merchants of Mogadore, Morocco, Fez, and other places in Northern Africa. The city seems to date back to the twelfth century, but was visited by no European until Laing reached it in 1826.

The practical now has the characteristic of the moment, enduring while some specific consideration can be held before the mind; as now we are reading and comprehending this sentence. Yet this same practical now must be a sensible fraction of the life of an ephemera, which lasts only for a single day. And it is then quite conceivable that in the case of beings of a far higher order than ourselves the practical now should include a sensible fraction of a whole human life; while to the infinitely supreme Being all that has taken place in history, and all that is anticipated in the future, will be one vast, comprehensive, ever-during nowe ("the Eternal Now").

"Relative, apparent, and common time," remarks Sir Isaac Newton, in his Principia, "is some sensible and external (whether accurate or unequable) measure of duration by means of motion, which is commonly used instead of true time; such as an hour, a day, a month, a year." In its applications, such relative time, when now used, is almost always corrected by an equation of time;

of which more hereafter.

Next, with regard to the measures of time, whether variable or accurate. A suitable measure of time, and withal

a natural one, is to be found in the earth's rotation about its axis; which measure will be found to possess the three requisites which must belong to every good measure-viz. (1) It must be of suitable size or magnitude; (2) it must be readily accessible, and admit of an easy application; (3) it must, if possible, be invariable.

(1) The sidereal day (see Moox) which is completed in the time occupied by the rotation of the earth about its axis will be found to have in itself all these requisites, though our limits will not admit of the exposition

of that.

But, admitting what has just been stated, we ought next to ascertain how we are to determine when a globe rotating about its axis, and at the same time transferred in space, has just completed one entire rotation. For this purpose, suppose two entirely similar globes to be placed as in Fig. 1, with the meridian P M of the one parallel to the P' M' of the other. Then, if the respective angular velocities of rotation of the globes be equal, the plane P' M' of the

[subsumed][merged small][ocr errors]
[ocr errors]

one will continue parallel to P M, and so at the end of one complete rotation P' M' will be found to be parallel to PM in the original position of the latter. Now, if instead of two globes, we suppose one globe, turning still with the same angular velocity, to have advanced during one rotation from the first of the two positions in the figure to the second, then the meridian PM will be in the

position P' M', and itself be parallel to the position which it had at first. Now, if the plane of P M passed through or coincided with the direction of a fixed star, P' M' would also sensibly coincide with the same, since the directions, such as PM and P' M', extending to the same fixed star, would be sensibly parallel. And so between two successive transits of the same fixed star would be accurately accomplished one complete rotation and also one sidereal day.

The sidereal day of astronomers begins when the vernal

equinox is on the meridian of the place of observation. As the position of the vernal equinox is affected by the very slow change due to the precession, this practical sidereal day is the veriest trifle less than the true. Moreover, the position of every terrestrial meridian is also very slowly changed, and the precession not quite that due to a uniform change. But all would make a difference in the observed time of but little more than one second in nineteen years, and therefore no correction is made for it, the whole being understood. The apparent rotation of the heavens being due to the actual rotation of the earth, it will, like the latter, be isochronous in the whole and in all its parts, which all the observations of sidereal time justify.

Of Solar Time, Mean Solar Time, Apparent Solar Time, and the Equation of Time.—If, as in Fig. 1, P M be, at any instant, the meridian, the plane of which passes through the visible place of the sun (affected by aberration), then to all places of which P M is the meridian, to which the sun is visible, the time will be that of apparent noon. Between that and the next succeeding noon the earth will have moved from P to P' (the extent of the motion being bere exaggerated). Before this (in accordance with what has been heretofore demonstrated), a sidereal day will have been accomplished, the meridian having in that period arrived at the position P' M, parallel to its first position, PM. But in order that the plane of the same meridian should a second time pass through the apparent place of the sun, P' M' must rotate still farther until it arrives at the position P' S, and then, and not before, will be completed the apparent solar day. The time meted out by these motions is apparent solar time. Now, the arc M'S in the plane of the earth's equator is (on a small scale) an are of right ascension, and P P', in the same plane, measures, on the large scale, the motion of the earth in its orbit, also in right ascension; and the angle at the sun measured by P P' is the alternate angle to M'PS. Hence the angular excess of motion M' PS above a whole rotation, between one noon and the next, is itself equal to the angular motion of the earth (orbital motion, that is) in right ascension in the same interval. Now, as will be demonstrated, the angular motion of the earth in right ascension from day to day is variable. Hence, although the earth's rotation is isochronous, the solar days must be unequal. But by combining a great number of them (comparing them with sidereal time), and then dividing by the whole number, we obtain the average or mean solar day.

There are two principal causes of the variation in the daily increment of the earth's right ascension. One of these is obliquity of the ecliptic (earth's orbit) to the equinoctial. Did the earth's motion around the sun take place in a circle, and if that motion itself were uniform, even then the motion in right ascension would be variable; for FIG. 2.

[blocks in formation]

then, although the motion in longitude from the equinox

E Fig. 2) would in one quarter of a year amount to 90° or E S, and the motion in right ascension, E R, be also 90°, yet as respects any intermediate point L the right ascension EA would be less than the longitude E L. The effect of this from day to day (the gain in right ascension being less than the average) would be to make the excess above a whole rotation to make out a solar day less than the average, and so the solar day be made too short for the average, or time too fast; so that, if the earth even revolved uniformly around the sun, solar time would be too fast from the equinox onward to the solstice, the difference, after a while, however, becoming less and less, until at the solstice

order; and (as in Fig. 3) the arc E' A' of right ascension being less than E' L', that of longitude; if each be subtracted from 90°, we shall have R A' greater than SL; or the motion in right ascension, in going from the solstice toward the equinox, will be greater than the motion in longitude, instead of less, as was true in the going from the equinox toward the solstice; though 90° will be completed in longitude as well as at right ascension at the equinoctial point E'.

The summning up of this is, that in consequence of the motion of the earth in an orbit oblique to the plane of the earth's equator (and therefore also to the equinoctial) solar time would be made too fast, as the earth was going from the equinox toward the solstice, this variation being, however, exactly overcome at the end of the one quarter of the year, when the earth would arrive at the solstice. But in going from the solstice toward the next equinox, the effect of the earth's oblique motion would be to make solar time at first too slow, as the earth was going from the solstice toward the next equinox; this variation also to be overcome at the end of the one quarter of a year, when the earth would arrive at the next equinox; and the right ascension of the earth thus be the same at the equinoxes and at the solstices as it would be if the earth had moved uniformly in the plane of the equinoctial, and so had kept mean time. Solar time would thus be right when the earth was at either of the equinoxes or of the solstices, while between any equinox and the succeeding solstice solar time would be too fast; but between any solstice and the succeeding equinox solar time would be too slow, there being four instants (viz. at the equinoxes and at the solstices) in the course of the year at which solar time, kept by the earth's motion, would be right, with four intervening intervals within which time thus kept would be alternately too fast and too slow : four intervals for the second half of the year would repeat the effects of the first.

But the earth does not revolve around the sun uniformly in a circle, but in an ellipse, with a variable angular motion. (See PLANET.) Yet the one-half of the revolution in the ellipse, from the perihelion P (or place nearest the sun) to the aphelion A (or place farthest from the sun), is accomplished in the same time with the other half revolution (from A to P); and either the same time in which a body moving in a circle at the distance C A (i. e. one-half of A P) would describe its half circumference. In going, then, from P to A, the earth at first moves faster than the average, and so makes the arc M'S in Fig. 1 (necessary to complete the solar day) too large; the day is thus made too long, and solar time thereby too slow, through the half year while the earth is passing from P to A (i. e. from about the 1st of January to about the 1st of July); the reverse being true, time made too fast, from the beginning of July to January (i. e. for the other half of the year), the positions at P and A, notwithstanding, being those at which the earth would be if it revolved in a circle uniformly at the mean distance A C, which is the one-half of P A. We have, then, from this cause (considered by itself), but two instants at which the irregularity in solar time disappears, and those half a year asunder, instead of one quarter of a year, as in the instance of irregularity due to obliquity, and the half-year periods beginning and ending at dates different from any of the four dates of time right, as respects obliquity.

Other small irregularities in the earth's elliptical motion, arising from her connection with the motions and also the

perturbations of the planets, slightly modify the results of

that motion as to solar time here described.

In Fig. 4 the variations from both causes now described are artificially represented, the bolder curve representing the effect of the obliquity, with the wave abore the horizontal line when time is too fast, the height of the wave at any date indicating proportionally how much too fast. The hollows of the waves at their several dates indicate time too slow, the depth of the depression indicating, protime would be neither too fast nor too slow from this cause portionally, how far too slow; the four dates at which being at the points of intersection at the equinoxes and solstices, as heretofore shown. The lighter curre, after a like fashion, indicates the effect of the elliptical shape of the earth's orbit, time being represented as thereby made too slow by the hollow of the wave extending from the beginning of January to the beginning of July. Now, the sum or the difference, as the case may be, of the perpendicular heights and depressions (positive and negative ordinates)-i. e. the combined effect of both causes-is marked by means of the third curve immediately beneath the others. On this it will be seen that the considerable effect of time too fast due to the obliquity on the 15th of April is balanced by the effect of time too slow due to the elliptical; and so time then is right. The small remaining effect of time too fast from the obliquity is balanced by the time too
