“ Sir Joseph Banks commissioned him to bring out in aquatint (a method of engraving then peculiar to Sandby) forty-eight plates drawn during a tour in Wales. Sandby displayed considerable power as a caricaturist in his attempt to ridicule the opposition of Hogarth to the plan for creating a public academy for the arts. In 1768 he was chosen a foundation-member of the Royal Academy and appointed chief drawing-master to the Royal Military Academy at Woolwich. He held this situation till 1799. Sandby is best remembered, however, by his water-colour paintings. ”
