in the form of an epizootic among the cattle, and especially 
milk cows. Its special lesions consisted of vesicoe, which 
affected the mucous membrane of the mouth, and, more espe¬ 
cially, the dental pad. The skin around the coronet and mam¬ 
mary gland, were also special seats of the disorder. My atten¬ 
tion was first called on September 2d, 1898, by a Mr. J. The 
history was, that he had a large short-horn cow, that seemed 
stiff and would not eat. I went to his place and found the cow, 
as described, with a calf a few weeks old at her side. The follow¬ 
ing symptoms were observed : Animal was very stiff, when forced 
to move, arched back, thus all four feet were brought together 
under the body. Heat and tenderness around the coronet 
bowels constipated, urine scanty, milk diminished in quantity ; 
temperature 103 ; circulation not much disturbed. Animal not 
taking any food or water ; looked very hollow. She would oc¬ 
casionally grind her teeth. Saliva was hanging from her mouth ; 
there was a peculiar smacking of the lips ; the muzzle was dry; 
slight discharge from nose. The breath was foetid. The 
mouth was sore, containing ulcerous patches, which were irreg¬ 
ular in size and shape. The dental pad was one dirty brown 
ulcer, tinged with yellow towards the centre. This ulcer was 
traversed by fissures. The other ulcers were on the lower jaw, 
behind the incisor teeth. Closer observation revealed small 
vesicse, or blebs, on the inside of the cheeks and lips. My diag¬ 
nosis was a form of aphthae. I gave croton oil, 30 drops ; fluid 
extract ginger, 2 drachms ; linseed oil, 4 ounces ; at one dose. 
I prescribed fluid extract nux vomicae, 1 ounce, aquae tounake 
8 ounces. Tablespoonful to be given morning and evening. I 
also left an aqueous solution of tannic acid, carbolic acid and 
glycerine, to be applied to the sores in the mouth three times a 
day. 
It was found that, by placing the feed well back on the 
tongue, she could eat. So she was fed in this way. Water 
was given with a drenching bottle. After a few days the case 
was marked by a gradual disappearance of acute symptoms, an 
increase in the quantity of milk, which had been reduced to 
almost nothing; obliteration of the raw surfaces, by a develop¬ 
ment of new epithelium, and a gradual cessation of lameness,, 
which was the last symptom to disappear. This, the first case, 
has been described in detail, as it is practically what was 
observed in the other cases, which were about seventy in num¬ 
ber, excepting a few complications, which I will mention. In 
two instances the cows aborted. In three or four cases, vesicles
