EPIZOOTIC LABI-GLOSSITIS. 
Elgin, III., Feb. 6, 1893. 
Editor Vet. Review : 
I am only too glad to help you in any way in the good 
work you are doing, so have sent you the following report 
of a disease which has prevailed to a very considerable ex¬ 
tent in this neighborhood. I have called it epizootic labi- 
glossitis, those organs being most affected. 
This disease affects both horses and cattle, but is most 
prevalent in the latter. My attention was first called to it in 
1892, in the following manner: 
I was requested by Mr.-, a large dairy-man in Kane 
Co., Ill., to visit his farm and examine his cows, as they were 
not giving near the milk they should, and would not eat. 
Upon arriving, I found in all 26 cows affected with the disease 
in a more or less advanced stage. The symptoms were more 
or less as follows: Temperature from 2 to 4 degrees above 
normal; bowels constipated ; saliva was flowing very abun¬ 
dantly, in some cases, as much as half a gallon being upon the 
floor before one cow; the tongue was protruding and raw ; 
muzzle dry; appetite more or less impaired ; in some cases, 
tongue and lips so sore that cows were not able to get feed into 
their mouths. Pulse varied according to severity of the case. 
The disease generally makes its appearance in the follow¬ 
ing manner: A small blistered condition is first observed 
upon the inferior portion of the upper lip; the blisters break, 
leaving a raw surface which soon becomes ulcerated and ex¬ 
tremely painful, rendering mastication difficult. The tongue 
is generally the next organ affected, first being blistered, the 
skin peeling off and ulceration setting in, the organ swelling 
in some cases as large again as it should be, and being ex¬ 
tremely painful and hot. Saliva flowing in great abundance, 
being hot and sticky. The disease extends as far back as the 
pharynx and larynx, in some cases—when it must be regarded 
as very serious—the animal exhibiting all the symptoms of
