The young man was taken from wooden bolt-making, sent up to London, and placed under Bartolozzi, an accomplished and very thriving designer and engraver, who formed one of the original members of the Royal Academy on its institution in 1768. Bartolozzi found his pupil apt. He made, indeed, rapid progress, and about 1772 received the Academy gold medals for drawings of 'Coriolanus taking leave of his family,' and 'Venus soliciting Vulcan to make armour for her son.' From 1774 to 1780 his name is to be found in the catalogues of the Academy as an exhibitor of various drawings, original and copied, in red and black chalks, after the manner his master had rendered popular. Sherwin had proved himself a vigorous, dashing draughtsman, standing high in his preceptor's good opinion, higher still in his own, and surely gaining the applause of the town. Quitting Bartolozzi, he set up for himself, taking an expensive house in St. James's Street. He there commenced a desultory system of designing, painting, and engraving; doing less engraving than anything else, however. It was his most legitimate occupation, but it was laborious, took time, was not very highly remunerated, and he wanted to make money--as much and as quickly as possible. He had patrons in plenty, eager for his graceful, facile drawings, prepared to pay good prices for them; and the man himself became a favourite in society. He was handsome, ready, good-natured; well pleased to array his shapely person in smart raiment, disport himself in the drawing-rooms of the noble and rich, and add his name to the unprofitable list of fashion's votaries.
