A H E Armenian jewellers fet precious {tones, particularly diamonds, to much advantage, 

 with a foil, which, under rofes or half brilliants, is remarkably beautiful, and is not fubje£b' 

 to tarnifli. Their method is as follows : An agate is cut, and highly polifhed, of the fliape 

 defired ; in a block of lead is formed a cavity of about its own fize ; over this is placed a bit 

 of tin, of the thicknefs of ftrong brown paper, fcraped bright. The agate is then placed on 

 the tin over the cavity, and ftruck with a mallet. The beautiful polifh the tin receives is 

 foarcely to be imagined. This is in general kept a fecret, and fuch foils fell for half and 

 three quarters of a dollar each. 



The jewellers, who are moflly Armenians, have a curious method of ornamenting watch-- 

 cafes and fimilar things, with diamonds and other ftones, by limply glueing them on. 



The ftoneis fet in filver or gold,, and the lower part of the metal made flat, or to corre- 

 fpond with the part to which it is to be fixed ; it is then warmed gently, and the glue ap- 

 plied, which is fo very ftrong that the parts never feparate. 



This glue, which may be applied to many purpofes, as it will ftrongly join bits of glafs or 

 poliflied fteel, is thus made :
