duke of York, younger son of Frederick, prince of Wales, whom there was then some intention 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 enabled 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 third 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 mentioned; 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 conceived him a fit person to take charge of the chronometer 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 difficulty extinguished. The result of the observation was satisfactory, the whole error from first setting sail, on a comparison with observations at Portsmouth, being only 1' 53½", a difference which would produce very little effect in calculations of longitude for ordinary practical purposes. For the reward of his services Mr Robison had made no stipulation, trusting to the consideration of government; but he was disappointed. Lord Anson was in his last illness, admiral Knowles was disgusted with the admiralty and the ministry, and the personal applications unaided by interest which he was obliged to make, were met with a cold silence which irritated his mind. It appears that at this period the reward he sought was the comparatively humble appointment of purser to a ship. In 1763, such a situation was offered to him by lord Sandwich, then first lord of the admiralty, in a vessel of 40 guns, which it is probable that a dawning of brighter prospects prompted him, certainly not to the regret of his admirers, to decline. Notwithstanding his having been connected with a branch of society not generally esteemed propitious to clerical pursuits, he is said to have still felt a lingering
