Pathology a Division of Biology 



Disease is the common lot of all forms of life, high as well as low, 

 animal as well as vegetable, and it is the special province of patho- 

 logy, the science of disease, to study life in its abnormal forms and 

 activities. Hence pathology is a division of biology, and it is in

 always been so clearly appreciated as they ought to be; in part 

 this may be explained on account of the very special stress placed 

 on its direct application to practical medicine in the service of the 

 art of healing. For this and other reasons pathology in many re-

 The early pathologists took the almost exclusive standpoint of
