What happened to Skinner after 1753 I have failed to discover. He is certainly an interesting person from a book-plate collector's point of view, and it is to be hoped something more about him may some day be brought to light. In considering his identity it is worth remembering that a little after his disappearance, viz. in 1755, another West of England engraver named Skinner--Matthew Skinner of Exeter, is found working on book-plates. He signs three examples, all designed in the Chippendale style--'Jean Eli Jaquéri de Moudon en Suisse, Né en 1732'; 'S^{r} Edm^{d} Thomas, Bart.,' and 'Peregrine Fra^{s} Thorne.' The two first are ordinary Chippendale examples, but in the third many implements of the soldier's art are introduced. Another very prolific engraver of book-plates--unknown except in that capacity--was 'Robert Mountaine.' His book-plates are frequently dated, but the dates are placed in the most obscure positions, and in the smallest of figures, so it needs a careful study of the engravings to discover them. He laboured wholly in the Chippendale style; his touch is peculiar, and his treatment graceful. Roughly speaking, he worked from 1740 to 1755. His signature varies--sometimes it is 'R.M.,' sometimes 'Mountaine.' The following are a few of his book-plates:-- Henry Bowles. W. Harrison, D.D., Fellow of C. C. C. Oxon. R. C. Cobbe. S. J. Collins. C. Blackstone. Ed. Gore, Kiddington, Oxon. John Duthy. John Hoadly, LL.D. [This is Dr. Hoadly, the versatile author of oratorios and comedies.] Sophia Penn. Jos. Portal. C. S. Powlet, Itchen. Geo. Powlet, Esq. John Sturgis. A list of nearly sixty book-plates by Mountaine is given in the _Ex Libris Journal_, ii. p. 46. Hogarth's book-plates have been already described in this volume. The 'W. H.' who signs certain examples, once wrongly ascribed to Hogarth, was a certain William Hibbart, who, like Skinner, was a Bath artist, and etched portraits after the manner of Worlidge. Lord De Tabley mentions that Worlidge himself executed a book-plate--that of the Honourable Henrietta Knight--which he signs in full. Worlidge was certainly a distinguished engraver; his etchings after Rembrandt are excellent and highly prized. He died in 1766.
