ing short description will be sufficient to show the great 
usefulness of this invention. A drawing or any other subject , 
intended to be printed is made on a stone with a pen and a 
particular ink or with a kind of chalk, which may be done with 
the same facility as on paper, and every person who can draw on 
paper may draw on this stone. By a simple chemical process 
this drawing is rendered capable of being printed off in any 
number of copies without the least alteration of any stroke or dot 
on it, so that the impressions are perfectly like the original, and 
by means of this invention the art obtains an advantage never 
known till now, both in preserving and multiplying the works 
of great masters in their perfect originality. 
In the application to letter-press printing this art may be 
likewise highly useful, as circular letters, &c., &c., written on this 
stone may be printed in any number and one hundred fair copies. 
ready for circulation may be taken in an hour. 
Amateurs and artists who wish to multiply their drawings may 
have them printed by Mr. Volweiller who furnishes a stone and 
the necessary materials for drawing and of whom further 
particulars may be had.
