S06 Art of Printing from Stone . 
For the method in relief, as it is called, nitric acid with 
half water is used* 
In the flat method less nitric acid is used. It is not to 
be supposed, that the surface is quite plain in this way ; 
but the lines are very little raised, so that they can scarce- 
ly be perceived to stand above the ground but by the 
finger* 
The works executed in stone are; 1, imitations of wood 
cuts : 3, imitations of engravings in the dotted manner : 
3, drawings : % music : 5, all kinds of writing : 6, maps : 
7, copperplates. 
The advantages of this method are, that it has a pecu- 
liar character, which cannot be represented by any other 
mode, while it gives a tolerable imitation of other me- 
thods ; and still more the celerity, with which it can be 
executed. A subject, that an artist could not finish in 
five or six days on copper, may be engraved on stone in 
one or two. While a copperplate printer is taking off 
six or seven hundred impressions, two thousand may be 
printed in this way. A copperplate will scarcely give a 
thousand good impressions, while in this way several 
thousands may be taken off, and the last be as perfect as 
the first. Thirty thousand have been taken off one de- 
sign at Vienna, and the last was as beautiful as the first. 
This is intended to be carried still farther, for the purpose 
of printing bank notes. The most expert music engraver 
can scarcely execute four pages of music on pewter in a 
day, but the engraver on stone can finish twice as much 
in that time. 
To enter into the particulars would take up too much 
room, but experience has shown, that this mode saves 
two thirds of the expense of engraving on copper or 
pewter. 
After having mentioned the advantages of printing 
from stone, it is just to point out its disadvantages^
