so much engrossed his thoughts, that he did not willingly converse on any other subject; nor was he so well pleased with the civilities of the greatest persons, as with the conversation of the mathematicians. An astronomical observation was sufficient to withhold him from court, or to call him away abruptly from the most illustrious assemblies; nor was there any hope of enjoying his company, without inviting some professor to keep him in temper, and engage him in discourse; nor was it possible, without this expedi-ent, to prevail upon him to sit for his picture.

Ibid. At Halle he continued his studies.

Mr. Barretier returned, on the 28th of April, 1735, to Halle, where he continued the remaining part of his life, of which it may not be improper to give a more particular

account.

At his settlement in the university, he determined to exert his privileges as master of arts, and to read publick lectures to the students; a design from which his father could not dissuade him, though he did not approve it; so certainly do honours or preferments, too soon conferred, infatuate the greatest capacities. He published an invitation to three lectures; one critical on the book of Job, another on astronomy, and a third upon ancient ecclesiastical history. But of this employment he was soon made weary by the petulance of his auditors, the fatigue which it occasioned, and the interruption of his studies which it produced, and, therefore, in a fortnight, he desisted wholly from his lectures, and never afterwards resumed them.

He then applied himself to the study of the law, almost against his own inclination, which, however, he conquered so far as to become a regular attendant on the lectures on that science, but spent all his other time upon different studies.

The first year of his residence at Halle was spent upon natural philosophy and mathematicks; and scarcely any author, ancient or modern, that has treated on those parts of learning was neglected by him, nor was he satisfied with the knowledge of what had been discovered by others, but

made new observations, and drew up immense calculations. for his own use.

He then returned to ecclesiastical history, and began to retouch his Account of Heresies, which he had begun at Schwabach: on this occasion he read the primitive writers with great accuracy, and formed a project of regulating the chronology of those ages; which produced a Chronological Dissertation on the succession of the Bishops of Rome, from St. Peter to Victor, printed in Latin at Utrecht, 1740.

He afterwards was wholly absorbed in application to polite literature, and read not only a multitude of writers in the Greek and Latin, but in the German, Dutch, French, Italian, English, and Arabick languages, and, in the last year of his life, he was engrossed by the study of inscriptions, medals, and antiquities of all nations.

In 1737 he resumed his design of finding a certain method of discovering the longitude, which he imagined himself to have attained by exact observations of the declination and inclination of the needle, and sent to the academy of sciences, and to the Royal society of London, at the same time, an account of his schemes; to which it was first answered by the Royal society, that it appeared the same with one which Mr. Whiston had laid before them; and afterwards by the academy of sciences, that his method was but very little different from one that had been proposed by M. de la Croix, and which was ingenious, but ineffectual.

Mr. Barretier, finding his invention already in the possession of two men eminent for mathematical knowledge, desisted from all inquiries after the longitude, and engaged in an examination of the Egyptian antiquities, which he proposed to free from their present obscurity, by deciphering the hieroglyphicks, and explaining their astronomy; but this design was interrupted by his death.

P. 384. Confidence and tranquillity.

Thus died Barretier, in the 20th year of his age, having given a proof how much may be performed in so short a

time by indefatigable diligence. He was not only master of many languages, but skilled almost in every science, and capable of distinguishing himself in every profession, except that of physick, from which he had been discouraged by remarking the diversity of opinions among those who had been consulted concerning his own disorders.

His learning, however vast, had not depressed or overburdened his natural faculties, for his genius always appeared predominant; and when he inquired into the various opinions of the writers of all ages, he reasoned and determined for himself, having a mind at once comprehensive and delicate, active and attentive. He was able to reason with the metaphysicians on the most abstruse questions, or to enliven the most unpleasing subjects by the gaiety of his fancy. He wrote with great elegance and dignity of style, and had the peculiar felicity of readiness and facility in every thing that he undertook, being able, without premeditation, to translate one language into another. He was no imitator, but struck out new tracks, and formed original systems. He had a quickness of apprehension, and firmness of memory, which enabled him to read with incredible rapidity, and, at the same time, to retain what he read, so as to be able to recollect and apply it. He turned over volumes in an instant, and selected what was useful for his purpose. He seldom made extracts, except of books which he could not procure when he might want them a second time, being always able to find in any author, with great expedition, what he had once read. He read over, in one winter, twenty vast folios; and the catalogue of books which he had borrowed, comprised fortyone pages in quarto, the writing close, and the titles abridged. He was a constant reader of literary journals.

With regard to common life he had some peculiarities. He could not bear musick, and if he was ever engaged at play could not attend to it. He neither loved wine nor entertainments, nor dancing, nor the sports of the field, nor relieved his studies with any other diversion than that of walking and conversation. He eat little flesh, and lived

almost wholly upon milk, tea, bread, fruits, and sweet

-meats.

He had great vivacity in his imagination, and ardour in his desires, which the easy method of his education had never repressed; he, therefore, conversed among those who had gained his confidence with great freedom, but his favourites were not numerous, and to others he was always reserved and silent, without the least inclination to discover his sentiments, or display his learning. He never fixed his choice upon any employment, nor confined his views to any profession, being desirous of nothing but knowledge, and entirely untainted with avarice or ambition. He preserved himself always independent, and was never known to be guilty of a lie. His constant application to learning suppressed those passions which betray others of his age to irregularities, and excluded all those temptations to which men are exposed by idleness or common amuse

ments.

MORIN".

LEWIS MORIN was born at Mans, on the 11th of July, 1635, of parents eminent for their piety. He was the eldest of sixteen children; a family to which their estate bore no proportion, and which, in persons less resigned to providence, would have caused great uneasiness and anxiety.

His parents omitted nothing in his education, which religion requires, and which their fortune could supply. Botany was the study that appeared to have taken possession of his inclination, as soon as the bent of his genius could be discovered. A countryman, who supplied the apothecaries of the place, was his first master, and was paid by him for his instructions with the little money that

he could procure, or that which was given him to buy something to eat after dinner. Thus abstinence and generosity discovered themselves with his passion for botany, and the gratification of a desire indifferent in itself, was procured by the exercise of two virtues.

He was soon master of all his instructer's knowledge, and was obliged to enlarge his acquaintance with plants, by observing them himself in the neighbourhood of Mans. Having finished his grammatical studies, he was sent to learn philosophy at Paris, whither he travelled on foot like a student in botany, and was careful not to lose such an opportunity of improvement.

When his course of philosophy was completed, he was determined, by his love of botany, to the profession of physick, and, from that time, engaged in a course of life, which was never exceeded, either by the ostentation of a philosopher, or the severity of an anchoret; for he confined himself to bread and water, and, at most, allowed himself no indulgence beyond fruits. By this method, he preserved a constant freedom and serenity of spirits, always equally proper for study; for his soul had no pretences to complain of being overwhelmed with matter.

This regimen, extraordinary as it was, had many advantages; for it preserved his health, an advantage which very few sufficiently regard; it gave him an authority to preach diet and abstinence to his patients; and it made him rich without the assistance of fortune; rich, not for himself, but for the poor, who were the only persons benefited by that artificial affluence, which, of all others, is most difficult to acquire. It is easy to imagine, that, while he practised in the midst of Paris the severe temperance of a hermit, Paris differed no otherwise, with regard to him, from a hermitage, than as it supplied him with books and the conversation of learned men.

In 1662, he was admitted doctor of physick. About that time Dr. Fagon, Dr. Longuet, and Dr. Galois, all eminent for their skill in botany, were employed in drawing up a catalogue of the plants in the Royal garden, which
