To the general principles of therapeutics laid down at 
pages 96 & feq. and to the praftical details of the fame fci- 
ence fo largely dwelt upon under every fpecies of our 
numerous catalogue of difeafes, we have nothing further 
to add. Diftnilfing, therefore, the fubjeft of the action 
of material agents on the human frame, we come to the

prepared, combined, and modified, to enfure their moll 
efficient operation. This embraces that branch of the 
healing art called Pharmacy or more properly Pharmaco-

in- the Pharmacopoeia to defignate the raw materials. In 
a more extended feries, it might be made to comprehend afl
