both Relief and Intaglio Processes were used. By this mode he produced a copy of Ugo da Carpi's Chiaroscuro Engraving of " Aeneas & Anchises," after Raphael, and a number of reproductions of drawings by Italian masters. A collection of these is in the Print Room of the British Museum. He also engraved in a similar manner a portrait of Sir Christopher Wren, by John Closterman, and a portrait of Dr. William Stukeley the Antiquary.

In Walpole's Catalogue of En- gravers, a notice of Kirkall's ' new method of printing, composed of etch- ing, mezzotints, and wooden stamps,' concludes with the following passage: 'He performed several prints in this manner, and did great 38 Colour Printers prior to 1834 justice to the drawing and expression of the masters he imitated.

' Walpole's statement of "no imitators " was in the course of time proved to be inaccurate, for it will be quite apparent to you, now that you have made a more technical acquaintance with Baxter's Process, that this method of Kirkall's of producing Pictorial Prints with a key plate, printed
