CORYZA GANGRENOSA. 43 



(See Medicines.) Decay, putrefaction, fermentation, are 

 true and scientific expressions, with no vague meaning. 

 Such, then, are the conditions embraced in the word con- 

 sumption, whether in men or animals. 



Contagion. — This term is applied to something, as 

 the virus of glanders, coming in contact with the body of 

 an animal in health, producing a similar disease to that 

 existing in the animal from which it came. In a word, 

 it is a specific poison. Few diseases of animals are con-

 small-pox, in sheep. Although many animals may be 

 taken sick one after another, this is no proof that the dis- 

 ease (excepting those just named) is contagious; for it 

 must be remembered that a number of animals, all situated 

 and cared for in the same way, are certainly subjected to 

 the same exciting causes that produced the disease in the 

 first animal that was afi*ected. Those that escaped the 

 disease were not predisposed to take it ; hence their ex- 

 emption from its efi'ects. 



Prevention. — Separate the sick from the well. All 

 buckets, or other materials, that were in contact with the 

 sick, will have to be cleansed and purified. (See Disin-

Convalescence. — A term applied to the time which

 restoration of the patient to perfect health.
