ART OF SHAVING. 



United with iulphuric acid to perfect faturatton, it yielded a 

 fait of a difficult folubility ; but if* this acid was added in 

 excels, the fait was readily foluble in. water. When iguite4 

 it became hard and infoluble in acids. I therefore do not 

 heiitate to believe, that this earth was zircoue, though not ab^ 

 folutely pure, but foiled with iron.

 This fubjeft is frequently treated in eonverfation ; and I am 

 pcrfuaded that many individuals will be glad to know what 

 can be fiated on the whole refpe&ing it. 



The fabrication of a good razor depends on fo many cir- Inftruftions for

 the hardening and the temper, that the artift himfelf after he 

 has exercifed his utmofl (kill, can in the laft inftance, feleft 

 fuch inftruments as are eminently fuperior to others, by trial 

 or actual ufe. I am not aw r are of any means of chilling a 

 good razor out of a number. All that I can fay in this refpect 

 is, that a bad razor cannot be eafily brought to a fine, or even
