The art of drawing, and painting in water-colours . Whereby a stranger to those arts may be immediately render'd capable of delineating any view or prospect with the utmost exactness; of Colouring any Print or Drawing in the most Beautiful Manner; and of taking off Medals instantly, by various Ways, never before made publick: Intermix'd with several curious Receipts for the Use of Painters, Statuaries, Founders, &c. With instructions for making transparent colours of every Sort; partly from some Curious Personages in Holland, France and Italy; but chiefly from a Manuscript of the Great Mr. Boyle; particularly a Receipt of that Gentleman's, for making a Blue Colour equal to Ultramarine.
