derful what a little perseverance will do,, 
especially with the aids which have been 
developed by modern science and art — one. 
of the most efficient of which is described 
in the next article, which is from the pen 
of the author of the previous articles on 
this subject. 
It gives us pleasure to be able to an- 
nounce that the author of the papers on 
Collodio Etching, which have recently 
appeared in these columns, has thrown a. 
more extended and minute series of in-

actual illustrations of the process itself. 
To those who have a taste for drawing-, 
and who desire an easy method of multi-

readers an illus- 
tration which 
shows as nearly 
as possible the 
results that may 
be attained by 
the simple art 
which has been 
described in a 
series of articles 
under the head of Collodio Etching. Our 
illustration is a wood engraving, and the 
artist has endeavored to show in facsimile 
the special features of pictures produced 
by this process. It will be seen that the 
lines are singularly free and sketchy, 
thus giving to the whole design a bold- 
ness which is not found in ordinary en- 
gravings. Of course, in order to make 
such drawings, in the first place requires 
some skill and experience, but it is won-
