NATURAL PHILOSOPHY. 



During the Session that has just closed, one Paper only 

 was read in this Section, but this was of especial merit, being 

 an account by Dr. P. Schidrowitz of the Synthesis and 

 the Properties and Uses of Modern Drugs. 



The compounds specially dwelt upon were the following : 

 Aniipyrin, Antifibrin, Phenacetin, Sulphonal, and Saccharin. 



The Lecture was well illustrated both with numerous 

 specimens and with experiments.
