INTRODUCTION. 59 



The former treats of the organs of the human body 

 the latter of those of the inferior animals. 

 Human Anatomy is divided into 



1. General Anatomy, which takes up the same tissue, 

 and follows it throughout the system, into every organ, 

 and examines it in all its relations and properties, physical, 

 organic, and vital. The celebrated Bichat is the founder 

 of General Anatomy. 



2. Special Anatomy, which takes up each organ, one by 

 one, and minutely examines all the different tissues of 

 which it is composed at the same time, showing the situa- 

 tion of each organ, its form, size, interior structure and 

 relations. 



The difference between these two kinds of Anatomy is 

 thus explained by Bichat : 



Chemistry, says he, has its simple bodies, as heat, light, 

 oxygen, hydrogen, carbon, &c., whose various combina- 

 tions form all the bodies we see on the face of the earth. 

 So Anatomy has its simple tissues, by whose varied combi- 

 nations all the different organs of animals, as well as the 

 human body, are formed. 



There are other divisions of Anatomy, as 



Surgical Anatomy, which treats of those portions of the 

 body having special reference to the treatment of Surgical 

 diseases. 



Eegional or Topographical Anatomy, when all the organs 

 in any particular region or section, are examined collec- 

 tively; and 



Pathological Anatomy, when the organs are examined in 

 a state of disease.
