THE INSTITUTES OF MEDICINE. 



The Institutes of Medicine are necessary m order to facilitate 

 the study of disease. 



Disease is either functional or organic. A functional disease 

 is one in which the physiological action is disturbed, but does 

 not show pathological lesions or morbid anatomy. A disease is 

 organic when it gives indication of morbid anatomy. A disease 

 may be both functional and organic ; but it may be purely func- 

 tional without showing any change of structure, the physiological 

 action alone being disturbed. Hence a good knowledge of physi- 

 ology and anatomy is necessary in order to understand disease, 

 — physiology for the functional diseases and anatomy and hist- 

 ology for the organic. 



Pathology is the doctrine of disease, i. e., it is the doctrine 

 of everything connected with morbid conditions, either func- 

 tional or organic. It is divided into : 



1. General Pathology. 



2. Special Pathology. 



General Pathology treats of diseased conditions in general 

 without reference to any special case. Special Pathology takes 

 into consideration special diseases and treats of their morbid 

 anatomy. 



Cinder general pathology the following factors come into con- 

 sideration : 



1. Etiology — Cause. 



2. Symptomatology — Semeiology, Symp- 



toms. 



3. Pathogeny — Pathogenesis (the genera- 



tion, production and development of 

 disease). 



4. Nosology — Classification and nomen- 



clature.
