This work, juft publiflied, will prove highly acceptable to 

 thofe who vvifli to attain a pra6lical acquamtance with the 

 fcience of which it treats. The author exhibits throughout 

 the -work a great degree of chemical knowledge; andhis 

 method of communicating knowledge to others is engaging. 

 With the praSical part of the various procelles in chemiltvy 

 he feems to be well acquainted ; and the accuracy and pre- 

 cifion with which he dei'cribes them, will render his work 

 valuable not only to tyros, but to proficients in the fcience. 

 Many of the experiments, fome of which are calculated t() 

 afford boih inftruaion and amufcment, are quite new; and 

 even in detailing experiments which are not new, particulars 

 not to be met \\°ith eifewhere are often given, which will be 

 ufeful to the praAical chemift.
