In order to determine the channel through which death oc- 

 curs, one must note the effect of the disease processes. If the 

 animal dies in a comatose condition, then the nervous system is 

 the cause; if syncope sets in, then the heart is at fault. A per- 

 son in a faint is comatose, but it is not deep enough to produce 

 death r in real death from coma, the stertorous breathing must 

 be present. All these conditions must be taken into considera- 

 tion in order to determine the correct cause of death. 



NOSOLOGY. 



By nosology we mean the classification and nomenclature of 

 disease. Diseases are divided into two general classes, constitu- 

 tional and local. Of the constitutional there are two kinds, ex- 

 ogenous and endogenous; of the local, eight, these referring to 

 the system affected ; they are the diseases of the respiratory sys- 

 tem, the digestive system, the circulatory system, the urinary, 

 the nervous, etc. The following is a simple form of the classifi- 

 cation of disease: 



1. Constitutional — 



a. Exogenous. 



b. Endogenous. 



2. Local. 



a. Diseases of the Respiratory System. 



b. Diseases of the Digestive System. 



c. Diseases of the Circulatory System. 



d. Diseases of the Urinary System. 



e. Diseases of the Nervous System. 



f. Diseases of the Generative System. 



g. Diseases of the Locomotory System, 

 h. Diseases of the Cutaneous System. 



A constitutional disease is one that affects the whole sys- 

 tem primarily ; if it localizes itself in any organ, it does so sec- 

 ondarily. A local disease is just the reverse ; it is one that affects 

 some part primarily, and the whole system secondarly, i. e., if 

 it does so at all. 



An exogenous disease is one arising from without the body, 

 i. e., the cause is from without. This includes all of the con-
