drawings of many varying character-

one process than another.

Of these methods of reproduction
there are three of primary import-
ance :

The swelled gelatine process;

The albumen process;

The bitumen process.

The first of these three methods is
used by Messrs. A. & C. Dawson in
this country, and called by them typo-
graphic etching. Acids do not enter

the other hand, the albumen pro-

reproduction (as, for instance, M.
Chefdeville) is capable of the most
