of the box or mould, with the tin-foil fticking 

 on the plafter, the convex-fide being now upper- 

 moft again, in which pofition it is to be kept in 

 the cabinet, after it becomes dry. To have an 

 impreflion very perfect, the thinneft tin-foil 

 ihould be made ufe of (b). 



The imprelTions taken in the foregoing man^ 

 ner almoil equal filver medals in beauty, and are 

 very durable : if the box or mould (/) be rather 

 larger than the impreflion of tin-foil, the plafter, 

 when poured on, runs round its edges, and forms 

 a kind of white frame, or circular border, round 

 the foil, whence the new-made medal appears 

 more neat and beautiful. If this tin-foil be gilt 

 with gold-leaf, by means of thin ifinglafs glue, 

 or boiled linfeed oil, the medal will refemble 

 gold. 



{h) This method does not in the leaft injure any medal 

 or coin. 



(/) Chip boxes, ufed by apothecaries, anfwer this purpofe* 

 and may be eaiily procured. A flip of paper wrapped round 

 any circular body with a flat furface, is equally conve- 

 nient.
