INTRODUCTION. 



It always gives me pleasure to give my experience 

 in our chosen profession, especially when it is in any 

 way connected with the analysis of urine, a subject 

 which I think is of vital importance in the diagnosis of 

 diseases, since by it we may arrive at a definite conclu- 

 sion as to the nature and location of the pathological 

 state. The older physicians for many years depended 

 entirely on a sugar and albumin test of urine. But 

 that no longer satisfies the investigating mind of the 

 scientific physician, since sugar and albumin are only 

 two of the many pathological elements found in the 

 urine. The methods of discovering the constituents 

 are few and simple, and most of the methods require 

 only a short time to complete them; so, you see, for 

 time spent and money expended on one hand and 

 knowledge gained and scientific treatment established 

 on the other, there is no sort of comparison. Now, 

 gentlemen, the value of these analyses will depend on 

 our knowledge of pathology. 



Pathology is only perverted Physiology. Since we 

 know that the urine is the sewage of the body and that
