I am not unacquainted with many ingenious In- 
ventions for taking off Medals, in Sulphur, Plaifter of 
Paris, Paper, , but, fince a Mould muft be formed 
for each of thefe, either of Clay, Horn, Plaifter of 
Parts, or fom'e other Materials, which requires a 
great deal of Trouble and Time to form, I believe 
this Way will be judged abundantly more conve- 
nient: And taking Impreffions on Paper from the 
Medals themfelves, by palling them through the 
Rolling-Prefs, and colouring them afterwards, is not 
only much more tedious, ineffectual, and lcfs pra- 
cticable (as a Gentleman cannot manage a Rolling- 
Prefs), but does Really a great deal of Injury to the 
Medals, by impairing the Sharpnefs of their molt 
delicate and expreflive Strokes j as I myfelf have 
found by repeated Experience. 
But Wax is always ready, and hurts not the finefl 
Medal in the leaft Degree; and, however brittle it 
may be fuppofed, the Moulds made thereof refill the 
Force of downright Prelfure, almoft as effectually as 
if they were made of Steel ; and might ferve to take 
off a thoufand Impreffions, were they not apt to 
crack, and the Marks of thofe Cracks to render 
what are taken from them afterwards, not quite fo 
elegant: But each Mould will ufually afford three 
or four good Impreffions, either coloured or plain. 
And, when they are done with, if the Paint is 
walked off clean, the fame Wax may be melted and 
employed again feveral times over. 
It is evident, that Impreffions taken thus, muft be 
cxaCtly what the Medals are from whence we take 
them, and that any-body who can borrow Medals 
from his Friends, may, in this manner, at the
