10. SOFT-GROUND ETCHING. 



Soft-ground etching seeks to imitate the effect of pencil or crayon 

 drawings. An etching-ground of i)omatum4ike consistency is spread 

 on a metal plate, and upon this is laid a sheet of paper having a grain 

 or tooth. On this paper the drawing is executed with a lead-pencil, 

 like an ordinary drawing. It is necessary, however, to use a hand-rest, 

 so that th3 pencil only may touch the paper. Upon careful removal of 

 the latter, the ground is lifted off with it wherever the pencil touched 

 it, and in proportion to the pressure used. The plate is then bitten in 

 as usual, and may be finished by additional biting, work with the point, 

 etc. This process is said to have been invented by Dietrich Meyer 

 (1572-1G58), but it has never been very extensively used.

 about 1815, by Louis Marvy, one of the best known workers in soft- 

 ground. 



11. THE SAND MANNER. 



In this process, which in its results resembles soft-ground etching, an 

 ordinary etching- ground is laid upon a metal plate, and is then pow- 

 dered with sand or other suitable material. This powder is made to 

 adhere to the ground by heat, without, however, allowing it to sink into 

 it. Upon the plate so prepared is spread the paper with the drawing 

 on it which is to be reproduced, and the lines are gone over with hard 

 styles of various sizes, so as to crush the particles of sand, etc., through 

 the ground. The plate is then etched, and finished as needed. In- 

 vented by J. n. Tischbein, jr., who described the process in a pamphlet 

 published in 1700. 



Frame 33. — Nos. IGl and 1G2, by the inventor. 



12. ETCHING ON GLASS, SO-CALLED. 



The term "etching," generally applied to this process, does not prop- 

 erly describe it. The drawing is executed upon a glass plate covered 

 with a sensitized collodion film. The instruments used are etching-
