CLIPPINGS OF PRACTICE. 
owner, who tirst denied it, at last said that about two months 
previously he had a dog which for two or three days had taken 
no food and had bitten whatever objects were presented to him; 
this dog, after showing signs of paralysis, was destroyed, but not 
until after he had bitten the horse on the lower lip. 
During that night my patient was much agitated. He bit his 
manger in his rage; nipped his fore arm ; frequently laid down 
and got up ; constantly trying to make water. A peculiar symp¬ 
tom is, that it was sufficient to slightly press upon one of the 
bars in the mouth to make the animal fall. He would then roll 
two or three times from left to right, then rise again and trem 
ble. His gait was always staggering, when he was compelled to 
walk. 
At the post mortem, the stomach was found empty, without 
lesion, and the laryngo-pharyngeal mucous membrane somewhat 
injected. 
TUBERCULOUS OPHTHALMIA. 
By M. Mathieu. 
This disease has been but imperfectly studied in veterinary 
medicine. The presence of tubercles in the eye had been ob¬ 
served, but tuberculous ophthalmia has never been described. The 
four cases observed by the author have enabled him to supply this 
want, which is of so much the more importance, as it is a sure evi¬ 
dence that phthisis pulmonalis, sometimes so very difficult to diag¬ 
nosticate, exists with it. 
At the outset, it is manifested by a slight flow of tears, often 
overlooked. After a while, if the eye is closely inspected, the 
iris is observed to change color. It becomes greyish, the surface 
is bosselated, and seems closer to the cornea; its small circum¬ 
ference becomes irregular ; the pupil contracts, and soon disap¬ 
pears completely. The iris then forms a complete diaphragm. 
During the disease the animal suffers intensely. The flow of 
tears is abundant; the eye-lids remain constantly closed; the 
iris assumes a jmllowish tint, and especially where the tubercu¬ 
lous deposits exist. The cornea is but little changed, and re-
