PATHOGENESIS. 



There can never be a great physician who is not at the same time 

 a good Physiologist. SIB ANDREW CLAKK, M.D. 



In every period of life the integrity of the digestive organs is the 

 best of all securities against invasion of every form of disease. 

 DB. ROBEBT DICK. 



Hunter was certainly no specialist. He strove earnestly to get an 

 insight into that principle of unity which is the great characteristic of

Exuberance of nutriment, as of many of the other goods of life, is
