better; the saliva was still abundant. The same treatment 
was continued. On the following day the strength of the 
peroxide solution was raised to forty per cent., and then 
sprayed in the mouth. From this time forward everything 
assumed a better aspect. The smell of the mouth had all 
disappeared ; the sloughs were all thrown off; the wounds 
became of a more healthy aspect; the edges showed the for¬ 
mation of the new layer of epithelium ; the saliva was less 
abundant, and the animal began to eat. The rapidity with 
which the peroxide acted in this case was surprising, the im¬ 
provement being more and more perceptible after every ap¬ 
plication of the H 2 0 2 . The horse was discharged on the 3d 
of May, if not entirely recovered, at least rapidly on the way 
toward complete restoration to health. 
Evidently in this case H 2 0 2 has proved the best medicinal 
agent for trouble of this kind, and for any foul-smelling ulcers 
of the mouth. It destroys the odor at once, and imparts a 
healthy appearance right from the start, if sprayed on imme¬ 
diately after the wound has been thoroughly cleaned. 
CARELESSNESS IN DIAGNOSIS. 
By the Same. 
There is nothing of great interest in this case, beyond the 
hint which it conveys of the importance of care and correct¬ 
ness in diagnosis. 
The patient was a small lap dog, brought to the hospital 
with the history that, though treated for three days by a 
prominent city veterinarian, he still would not eat, and was 
constantly salivating. The owner did not know what name 
the veterinarian had given the complaint at his first visit 
when he first saw the dog, but on the second day afterwards 
he told the owner the dog had a severe sore throat, and gave 
her a liniment to apply externally, with a prescription to ad¬ 
minister internally. 
On examining him, I failed entirely to discover any symp¬ 
toms of sore throat. But I found the breath very foetid, with 
continual salivation, and the tongue hanging out of the mouth, 
and the owner said the animal had rapidly emaciated, and had
