TYPHOID FEVER; OR, CONTAGIOUS INFLUENZA IN THE HORSE.

stables into which it has been introduced; it is also serious from 
a pecuniary standpoint, as the inability of a number of horses 
to work results in serious loss to the community. In addition 
to these facts, a large number of horses die of this disease 
especially in the beginning of the outbreak; these considera¬ 
tions, therefore, make the disease a very serious one. In 
isolated cases the disease is not so serious, but is more to be 
feared in young than in well-matured horses. Horses that are 
idle, or sale horses, suffer much more from this disease than do 
horses regularly at work. 
The prognosis will also depend largely upon the localization 
of the disease. If it localizes itself upon the digestive organs 
the animal is likely to make a good recovery; in rare instances, 
the patient may die fiom exhaustion when there is a persistent 
diarrhoea. 
Should the disease become localized upon the respiratory 
oigans, it is then much more serious, under any conditions, and 
is a very common localization in young, green, vigorous sale 
horses. Other complications are more or less serious, accord- 
ing to the organ compromised ; congestion of any portion of the 
neivous system may soon have a fatal termination, due to inter¬ 
ference with the function of these centers, and its influence upon 
respiration and circulation. 
When influenza, or typhoid fever, is complicated with founder 
the prognosis is a serious one; it is a complication not often met 
with, and which will sometimes yield readily to energetic treat¬ 
ment, but not infrequently several months are required for 
complete convalescence. I had two instances of this among 
some gieen brev r ery stock last Spring (1893); these horses suffered 
from the founder complication for over five months after all other 
symptoms of the disease had di s appea red. 
The prognosis in other complications varies with the locali¬ 
zation. Anasarca of the head is likely to interfere with respira¬ 
tion. Oedematous infiltration of the glottis terminates speedily 
in death. These anasarcous complications at rare intervals will 
take on the form oi acute suppurative erysipelatous disease. One
