 and to give some idea of the pleasure the microscopist enjoys. 



The President gave a short address " On the Life History of 

 Ferns," showing the value the microscope had been in defining their 

 organization.

 to the valuable aid of the microscope in physiological research ; and

 functions, proceeded to describe the characters of healthy urine, and 

 the microscopic aj)pearances of urea, sugar, and the various salts met 

 with in deposits. He also dwelt upon the means of diagnosis afforded
