are as it were, curbed and concentrated; and continual forrow and anguish of mind render the fluids of the body thick, and the blood unapt for a due circulation, whence proceed many chronic difeafes: it is therefore, on all accounts, as much our intereft as our duty, to keep the paffions within due bounds, and to preferve an inward ferenity, calmness and tranquillity.

REGIMEN, in chemistry, fignifies the due regulation of fire. See the article FIRE. REGIMEN, in grammar, that part of fyntax, or conftruction, which regulates the dependency of words, and the alterations which one occasions in another.

Regimen is threefold, of nouns, of verbs, and of indeclinable words. See NOUN, VERB, and INDECLINABLE.

The regimen of latin-fubftantive nouns is moftly of the genitive cafe; but that of adjectives, is of the genitive, dative, accufative and ablative,

The regimen of verbs may be diftributed into three claffes, the firft of which is the regimen of verbs perfonal; the fecond is that of verbs imperfonal; and the third that of the infinitives, participles, gerunds, and fupines. See the articles VERB, PARTICIPLE, &c.

The regimen of indeclinable words is that of the adverbs, prepofitions, interjections and conjunctions. See the ar ticles ADVERB, PREPOSITION, &c. In general, the regimen, or conftitution of government, is almost intirely arbitrary, and varies greatly in all languages. For one language forms its regimen by cafes, as the latin and greek. Others, inftead of cafes, make ufe only of small particles, as the english by of, to, &c. The french, ipanish, and italian by de, a, da, &c. There are, however, fome few maxims which hold good in every language, as, 1. That there is no nominative cafe in any fentence but has a reference to fome verb either expreffed or underflood. 2. That there is no verb which has not its nominative cafe expressed or understood, though in the latin before an infinitive, there is an accufative. 3. That there is no adjective but has a relation to fome fubftantive. 4. That there is no genitive cafe but is governed by fome other noun. The rule does not to apparently hold in the modern, as in the antient languages, in regard, the particles of, de, &c. which are the proper figns of the genitive cafe, are frequently used as prepofitions. 5. That

Sometimes thefe different governments have a power of changing the fenfe according to the different cultom of languages, in which cafe the particular use of languages must be always confulted. There is one very common fault committed in regimen, which fhould be carefully avoided by accurate writers, viz. the using two verbs that require different cafes together, as only governing one cafe, as in this example, " after em"bracing and giving his bleffing to his "fon," where," embracing," requires an accufative cafe, and " giving," a dative. The fame is to be oblerved in the regimen of nouns.

REGIMENT, in war, is a body of men, either horfe or foot, commanded by a colonel.

Each regiment of foot is divided into companies, but the number of companies is not always alike, though our regi. ments generally confift of thirteen companies, one of which is always grenadiers.

Regiments of horse most commonly confit of fix troops, but fome have nine. Regiments of dragoons, in time of war, are generally compofed of eight troops, and in time of peace, of fix. Each regiment has a chaplain and a furgeon. See the articles TROOP and COMPANY. Some german regiments confit of two thousand foot, and the regiment of Picardy in France, confits of 120 companies,

or 6000 men. REGIO ASSENSU, a writ by which the king gives his royal affent to the election of a bishop.

The yellow wafted, greyish green regulus, without a creft: this is a very elegant little bird, about the fize of the former fpecies; the fides of its head are ornamented with an oblong yellow line, running from the eyes to the hinder part of the head. See plate CCXXXI. fig. 3.

REGULUS, in chemistry, an imperfect metallic fubftance, that falls to the bottom of the crucible, in the melting of ores, or impure metallic substances.

This operation almost always requires the addition of fuch ingredients as take away the mutual connection between the parts to be separated; that is, the menftrual virtue, by means of which one keeps the other in a ftate of diffolution. For instance, the reguline part of antimony, and mineral fulphur, mutually diffolve each other, and conftitute crude antimony; nor can they be feparated by fire alone without deftroying the regulus: but if you add iron, copper, filver, &c. which are more thoroughly penetrated by fulphur, then the regulus of antimony is Leed of the fulphur, and being heavier

than the additional bodies then joined to it, finks to the bottom. See FLUX. Regulus of antimony is of three kinds, viz. the regulus of antimony, fimply fo called, martial regulus of antimony, and ftellated regulus of antimony. 1. The first is prepared as follows: Take antimony, nitre, and crude tartar, of each equal parts; grind them separately into a powder, then mix, and rub them all together; after which, throw the powder by degrees into a red hot crucible, taking care to break the cruft, which forms on the furface, with an iron rod; when the detonation is over, let a ftrong fire be made, that the matter may flow like water, then pour it out into a warm greased cone, which is to be gently ftruck on the fides, that the regulus may feparate and fall to the bottom; when grown cold, let the regulus be cleaned from the fcoriæ that lie a top of it. 2. Martial regulus of antimony is thus made: take antimony and nitre of each a pound; and crude tartar half a pound; and fmall pieces of iron, half a pound: heat the iron in a crucible to a white heat: then gradually add the other ingredients, firft powdered and mixed together, and proceed in the fame manner as in the foregoing procefs. 3. Stellated regulus of antimony is made by melting the martial regulus feveral times with fresh nitre and tartar.

The foregoing reguli are at prefent rarely, if ever, made ufe of in medicine: the emetic cups, and perpetual pills, formerly made from them, have long been laid afide, as precarious and unfafe; but the fcoriæ produced in these several proceffes, afford medicines lefs violent, fome of which are in confiderable efteem. However, they are of ufe in feveral mechanic arts, and particularly in mixing with tin, in making pewter. See PEWTER.

Relations make the largest clafs of our perceptions, fince every fingle object admits of almoft innumerable comparisons with others thus, if we compare one thing with another in refpect of bulk, we get the ideas of greater, lefs, or equality; if in refpect of time, of older and younger; and fo for other relations, which we can purfue at pleafure, almost without end; whence it is easy to conceive, how very extenfive this tribe of our perceptions must be. However, here, as well as in the other kinds of our complex ideas, we bound ourfelves for the most part to fuch comparisons, as the exigencies of fociety, the wants of life, and the different profeffions of men render neceffary; and are more or less ac curate in tracing out the relations of things, according to the degree of importance they appear to have in these refpects. The relations of men one to another, arifing either from the ties of blood, their feveral ranks and places in the community, or a mutual intercourfe of good offices, being of great weight and concern in the commerce of life, have in a particular manner engaged our attention, and are therefore very minutely defcribed. For the fame reafon men have found it neceffary, to determine as exactly as poffible, the various dependence of things, as their happiness is nearly connected with this knowledge. When we confider objects merely in refpect of existence, as either giving or receiving it, we come by the relative ideas of caufe and effect, which are very nearly connected with the welfare of mankind; it being evident, that the several schemes and purposes of life are all conducted upon a previous fuppofition, that certain known causes will have their usual regular effects, and such and fuch actions be attended with fuch and fuch confequences. See the articles CAUSE, EFFECT, and EXPERIMENTAL PHILOSOPHY.

But there are other relations of this kind, as when we alfo take in the additional gifts of a capacity for happiness, and the means of attaining it; which conftitutes the relation of creator and creature, in the more folemn acceptation
