discoverer. In addition to facility of transport', and of giving the 
exact lines penned or drawn by the artist, it has also the recom- 
mendation of economy ; and although we do not now mention the 
cost of the specimens given, until we have more experience in the 
working of the art, we can state, that it is more moderate than any 
other style of engraving or lithography we have yet practised. _ 
et The mode of delineation for which I propose the name of 
Papyrography, is a peculiar application of the anastatic art. 
Anastatic printing consists in transferring to a plate of zinc any 
design made with an oily material on paper. From the impression 
so transferred, any number of copies can be taken on paper by the 
same process as in ordinary zincography or lithography. 
“ The original design on paper, from which the zinc plate is to 
receive its impression, may be produced either by printing (from 
fyp e s> copperplate, wood, stone, &c.), or by the manual process of 
writing or drawing. The only requisite is, that the vehicle for 
this design be of an oleaginous nature. In the case of letterpress 
and engravings, the oily matter is supplied by the printer’ s ink ; 
but in regard to drawings, there are difficulties in the way of using 
greasy substances, which are avoided by mixing up the colouring 
matter, not with grease but with soap . Thus (as is the case also 
m lithography), the inks used for writing, and the chalks for draw- 
ing, are made with a soapy ingredient. In the act of transferring 
the design to the zinc, an acid is employed, which neutralizes the 
condition ^ ^ ^ br ‘ ngS th ® latter back to its original oily 
“ Anastatic printing was originally applied only to the repro- 
duce and multiplication of impressions from type or 3 
P ates. It was afterwards found, that the soapy ink used by
