ITALY. LETTER IV. 



I pafs over the Coral Manufactory, as having 

 been exactly defcribed in the Giornale d'ltdia, 

 and agreeing with a like manufactory at Leg- 

 horn. 



The manipulation of grinding and polifoing 

 Diamonds is here the fame as at Amfterdam. 



The Cryjial Manufactory at Venice, the Looking- 

 glafs Manufactory at Murano, and the Glajieries at 

 the fame place, are lefs remarkable at prefent, fmce 

 good ones are now common every where, and the 

 French, at S. Gobin, by cafling, produce looking- 

 glafles of a larger furface than the Venetian prac- 

 tice of blowing will allow. In the Cryjial Manufac- 

 tory, they make not only different glafs enamelling 

 frittas, which fell all over Europe, but likewife a 

 white fritta, for the Venetian buckle-manufactory. 

 The Murano glafs-makers furnim- Italy with bottles 

 and glafies ; they, make the thin Florentine-oil and 

 wine-bottles, at fo cheap a price, that they bear 

 the carriage by mules to the other fide of the 

 Apennines. 



The refining of borax and camphor, \htfublima- 

 ticn of mercury and cinnabar, &c. have ceafed to 

 be fecrets of the Venetians, as being now common 

 in Holland, at London, and Paris. They continue 

 {till to make theriaca in convents and in apotheca- 

 ries mops.
