studied algebra, the eleventh and twelfth books of Euclid, spherical trigonometry, conic sections, and the general principles of astronomy. The third class went on in astronomy and perspective, read a part of Sir Isaac Newton's principles of mathematical philosophy, and had a course of experiments for illustrating them performed and explained to them.

Those who composed the fourth class read a system of fluxions, the doctrine of chances, and the remainder of Newton's principles.

In 1742 he published his treatise on fluxions, a work which is superior to all praise. About this time we find him engaged in promoting several public works of great utility; such as the building an astronomical observatory

Edinburgh; a plan for improving

the natural history and settling the geography of the Orkney and Shetland islands; and another for discovering a north-east passage to the South Seas.

But while he was thus employed, the rebellion broke out in Scotland in favour of the Pretender; and as Mr. Maclaurin had exerted himself in defence of the king and religion, as by law established, he was under the necessity of withdrawing to England when the rebels approached Edinburgh. He was hospitably entertained by the Archbishop of York, who had a great esteem for him, and kept up a regular correspondence with him after his return to Edinburgh.

he had undergone. Still he continued his favourite studies, and employed himself in finishing his excellent account of Sir Isaac Newton's philosophical discoveries. While he was dictating the conclusion of this work, in which he proves, in the noblest manner, the wisdom, power, goodness, and other attributes of the Deity, his amanuensis observed a remarkable alteration in his voice and manner, No pulse could then be felt, and his hands and feet were already cold. Notwithstanding this extremely weak condition, he sat in his chair and conversed with his friend Dr. Monro, with his usual serenity and strength of reasoning, desiring the doctor to account for a phenomenon which he then observed in himself. Flashes of fire seemed to dart from his eyes, while in the mean time,

his sight was failing, so that he could scarcely distinguish one object from another. He then desired to be laid on his bed, where, with all the tranquillity and fervent piety of a christian, he expired without any pain or struggle, June 4, 1746. Dr. Monro, who pronounced his eulogium at the next meeting of the university, after displaying the acute intellectual powers and extensive learning of his deceased. friend, observed that he was still more to be admired for his superior qualities of the heart, for his sincere love of God and men, his convivial benevolence and unaffected piety, and for the warmth and constancy of his friendship.

JOHN PICUS, OF MIRANDULA.

THIS illustrious scholar, who adorned his high birth by the most brilliant talents as well as by his pre-eminent virtues, was the son of John Francis Picus, Prince of Mirandula in Italy, and born there February 24, 1463.

He was but an infant when his father died; and the care of his education devolved upon his mother, who provided him with the best masters in every accomplishment which at that period was deemed necessary to form the gentleman and the scholar. His progress in polite learning was such as to surpass the most sanguine expecta
