horse differ from any other of the inflammatory diseases which 
affect this animal. 
At one time, however, this general condition was confounded 
with anthracoid fever to such an extent that writers have main¬ 
tained that it was only a slightly different form of this disease. 
But the color of the mucous membranes is by no means that of 
anthrax fever, in which the violet color of the gums is not seen, 
the blood of typhoid fever having properties which are the very 
opposite of those seen in anthrax, which does not coagulate or 
oxidize on exposure to air. 
Anthracoid fever always begins by a violent excitement of 
the animal, while in typhoid there is always a true stupefaction 
from the very beginning of the disease. Anthrax fever is easily 
produced in the rabbit and guinea-pig by inoculation, while the 
blood of typhoid gives no results. In all cases there are sure 
and simple means of distinguishing these two diseases from 
each other, so that a correct diagnosis may be made at the first 
visit, and almost all practitioners do so when they see the closed 
and tearful eyes of a sick animal. It is therefore only neces¬ 
sary to make a diagnosis of the localization of the disease. 
When, after two or three days localization is found upon the 
intestine, abdominal pains are noticed, the dung, which was at 
first hard, soon becomes thin and watery. 
When the disease is located upon the respiratoiy organs, 
the early symptoms are somewhat obscure; aftei tv o 01 three 
days there is a slight dullness on one side of the chest, then all 
doubt is expelled. As regards other localizations, they are 
still more easily recognized, when there is congestion of nerve 
centers. The animals cannot support themselves, and fall to 
the ground; when there is founder there is then the chaiacter- 
istic symptoms of this disease. It is important to recognize the 
complication, for this fact must be taken into consideration in 
the treatment. 
PROGNOSIS. —The prognosis of influenza, or typhoid fever, 
is serious, from the fact that it is contagious in its character, 
and tends to spread among those animals confined in those
