Use of the Microscope in Pharmacy.

I. Use of the Simple Microscope. — a. The student of pharmacy 

 learns early in his college days that the simple microscope is almost 

 indispensable while pursuing the study of botany. The importance of 

 botany is recognized in every pharmaceutical college, because its prin- 

 ciples rest at the foundation of the knowledge of vegetable drugs. The 

 proportion of animal drugs used to-day is very small, so that the study 

 of zoology in colleges of pharmacy is usually overlooked. 



b. In order to study drugs, the pharmacist classifies them according 

 to their organileptic and other characteristics. This system is not with- 

 out fault, but it is nearest perfec': of any that has been devised, and it 

 has been adopted by all works on materia medica which are intended 

 solely for the use of pharmacists. While many of the physical charac- 

 teristics of the veeetable drusfs can be studied with the unaided eye,
