296 jealousies in the race, but each might be seen in turn helping forward the other, and a more interesting sight than this cannot readily be conceived. The letters of Mr. Hume to Dr. Robertson are full of amiable feeling, and of that light, cheerful raillery, in which the historian of England so much delighted to indulge, and which contrasted so pleasingly with the gravity and dignity of his writings. "Next week," he says, in one of these letters, "I am pub- lished, and then I expect a constant comparison will be made between Dr. Robertson and Mr. Hume. I shall tell you in a few weeks which of these heroes is likely to prevail. Meanwhile, I can inform both of them for their comforts, that their combat is not likely to make half so much noise as that between Broughton and the one-eyed coachman." Dr. Robertson in person was rather above the middle size, with an apparently ordinary degree of physical strength. His eye was intelligent, and his features regular and manly. "He appeared," says his biographer, "to greatest advantage in his com- plete clerical dress, and was more remarkable for gravity and dignity in discharging the functions of his public stations, than for ease or grace in private society." His moral character was unimpeachable. His manners were mild and conciliating, and all his dispositions amiable. "He was," says Dr. Erskine, "temperate, without austerity; condescending and affable, without meanness; and in expense, neither sordid nor prodigal. He could feel an injury, yet bridle his passion; was grave, not sullen; steady, not obstinate; friendly, not officious; prudent and cautious, not timid." He left behind him three sons and two daughters. The eldest son adopted the profession of the law, and passed through its highest honours. His two younger sons entered the army. His elder daughter was married to Mr. Brydone, author of the Tour in Sicily and Malta; the youngest, to John Russell, Esq., clerk to the signet. His two younger sons rose to high rank in the army, and the elder of the two especially distinguished himself in India under Lord Cornwallis.1 In the year 1781 Dr. Robertson was elected one of the foreign members of the Academy of Sciences at Padua, and in 1783 one of the foreign members of the Imperial Academy of Sciences at St. Peters- burg. The Empress Catherine was so much de- lighted with his works, that she presented him, through Dr. Rogerson, with a handsome gold enam- elled snuff-box, richly set with diamonds. He was the founder of the Royal Society of Edinburgh, and exerted himself with his usual zeal, not only in form- ing the plan of that institution, but in carrying it on after it was established. ROBISON, DR. JOHN, an eminent mechanical philosopher, and professor of natural philosophy in the university of Edinburgh, was the son of John Robison, a merchant in Glasgow, and was born there in the year I739.a The first part of his education he received at the grammar-school of Glasgow, whence he entered as a student of the university of Glasgow so early as the year 1750, and took the degree of 1 It may further be mentioned, that his niece, Miss Eleanor Syme, the daughter of one of his sisters, was the mother of one of the greatest men of the passing age, Lord Brougham, who wrote the life of his uncle above alluded to; and that Mr. Brydone's eldest daughter having married the late Earl of Minto. their second daughter became the wife of Lord John (now Earl) Russell, the eminent constitutional statesman, whose name stands honourably associated with all the great political reforms of the present day. 8 Memoir by Professor Playfair: Trans. Royal Society, Edinburgh, vii. 495. Master of Arts in 1756. What progress he made in his early studies is not known, and in after-life he used to speak lightly of his early proficiency, and accuse himself of want of application. In the year following his graduation he made a proposal to be appointed assistant to Mr. Dick, professor of natural philosophy, in place of the son of that gentleman, who had just died; but was considered too young for the important duty. At that time his friends had wished him to study for the church; but preferring some em- ployment in which his mechanical pursuits might be indulged, he turned his eyes towards London. Profes- sor Dick and Dr. Simson sent along with him recom- mendations to Dr. Blair, prebendary of Westminster, who might have had influence to procure for him the situation of tutor in mathematics and navigation to the Duke of York, younger son of Frederick Prince of Wales, whom there was then some inten- tion of educating for the navy. The plan was given up, and Robison received a severe disappointment, but the event served as his introduction to an excellent friend, Admiral Knowles, a gentleman whose son was to have attended the duke on his voyage. Young Mr. Knowles' nautical education was not to be given up with that of the duke; and his father, perceiving Robison's knowledge of mechanical philosophy, employed him to take charge of the instruction of his son while at sea. Mr. Robison sailed from Spithead in 1759 with the fleet which assisted the land forces in the taking of Quebec. His pupil was a midshipman in the admiral's ship, in which he was himself rated of the same rank. Two years of such active service as followed this expedition en- abled Robison to make many observations, and collect a fund of practical knowledge, while he was sometimes usefully employed in making surveys. On his return on the 3d of August, he was a sufferer from the sea-scurvy, which had disabled the greater part of the crew. At this time Mr. Robison seems to have had a surfeit of a sailor's life, one which, however pleasing for a limited time, as serving to exemplify his favourite studies, possessed perhaps few charms as a profession to a man of studious habits. He intended to resume the discarded study of theology; but an invitation from Admiral Knowles to live with him in the country, and assist in his experiments, prevailed. "What these experiments were," says Mr. Robison's biographer, "is not men- tioned; but they probably related to ship-building, a subject which the admiral had studied with great attention." He had not been thus situated many months when his young friend and pupil Lieutenant Knowles was appointed to the command of the Peregrine sloop of war of 20 guns, and probably from a passion for the sea recurring, after recovery from his disorder, and a residence in the country, Robison accompanied him. At this period his ambition seems to have been limited to the situation of purser to his friend's vessel. On his return from a voyage, during which he visited Lisbon before the traces of the great earthquake had been effaced, he again took up his residence with Admiral Knowles. By his patron he was soon afterwards recommended to Lord Anson, then first lord of the admiralty, who con- ceived him a fit person to take charge of the chron- ometer constructed, after many years of patient labour, by Mr. Harrison, on a trial voyage to the West Indies, in which its accuracy was to be tried, at the suggestion of the Board of Longitude. On the return, which was hastened by the dread of a Spanish invasion of St. Domingo, Mr. Robison suffered all the hardships of the most adventurous voyage, from the rudder being broken in a gale of wind, to the ship's catching fire, and being with diffi.-
