unsized spongy papers, or between two cloths, or other 
substances capable of absorbing the superfluous mois- 
ture from the thin paper ; when it has been slightly pres- 
sed between such thick spongy papers, or other sub* 
stances, by the hand or otherwise, lay the said thin pa- 
per, so moistened and pressed, upon or under the side 
of the writing which is to be copied, and in such man- 
ner that the one side of the said moistened paper shall be 
in contact all over the side of the said writing, so intend-

with the thin moistened paper intended to receive the 
copy, (placed respectively as above directed,) upon the 
board of a common rolling-press, or of that of which a 
description and drawing are hereunder written and drawn,

said press, in the same manner as is used in printing by 
copper-plates ; or instead of using the said or any rol-

subject them to any other pressure sufficient for the 
purpose : by means of which pressure, in whatever 
manner applied, part of the ink of the writing intend-
