The engravers whose work may be safely considered of high quality are R. De Launay, Bertonnier, Villerey, P. Savart, H. Dupont, Girardet, J. P. Marillien, L. Petit, J. F. Ribault, Chifflart, and V. Foulquier. Towards the end of the century photography came and gradually crowded out the small line engravers.
An etching is a drawing done with a needle point upon a sheet of metal protected by a thin impervious coat of soft varnish. The lines made by the etching needle pierce the varnish or “ground,” and reach down to the metal, usually copper, exposing it in those places. When the drawing is complete the plate is put into a bath of strong water, usually dilute nitric acid, and wherever the surface is not protected by the ground the acid will eat away the metal.
When now the ground is cleaned off with the help of turpentine, the original design will be seen transferred to the surface of the copper in the form of dull lines, shallow if the acid has only been allowed to act for a short time, but broad, deep and irregular if the “biting” has been long. So that an etching always has a little more “effect” than was put into the original work.
It is not necessary here to enter into the mysteries of “stopping out,” and several other variations of procedure, but it is sufficient to say that variations of tone and texture can be obtained; but, in fact, so far as book illustrations go, the etchings I know of are always simple, and the best of them are those by George Cruickshank.
The printing of etchings is analogous to that of line engravings, and a similar ink is used. A strong press is required, the paper is damped, and the impression is in slight relief. Line engravings are always printed in the same way as a visiting card, the untouched parts are clean, and print white, but in the case of etchings more ink is usually left, so that the untouched surfaces often show grey, none of the ink having been allowed to remain upon the plate. The French call this “retroussage,” and printers can produce strange effects by its use. A bad etching can be made to look like a good one; a good etching can be made to look weak and wretched. In fact, a clever artist printer can produce a capital picture from a plate which has nothing at all on it but the ink.
Etchings first appeared in English books about the end of the seventeenth century, but they are seldom signed, neither are they good. There is an etched frontispiece to Latroo’s “English Roque,” 1665, and another to “Æsop’s Fables,” published in the same year.
Wenceslaus Hollar, a Bohemian who worked in London, illustrated a few English books with etchings in the seventeenth century. Soft ground etchings printed in red and black appear in Pennant’s “Account of London,” printed in 1795. In the eighteenth and early nineteenth centuries William Blake made a few etchings for book illustrations. In the nineteenth century came Alken’s etchings of animals, usually coloured, Samuel Hewitt, Doyle, and especially the excellent work of George Cruickshank, which was very much admired by John Ruskin.

Combined with line engraving a number of small illustrations were published in the nineteenth century. They were etched on steel, and carefully finished with small line work, with ruled skies. They are generally classed as engravings, but should, I think, rather be called etchings.
