AND ITS DISEASES. 157 



and the alterative and physic balls. On the following day there was an 

 ulcer on the centre of the cornea, with much appearance of pain and im- 

 patience of light. Apply an infusion of digitalis, with the liquor plumbi 

 diacetatis. He was taken away on the twelfth day, the mange apparently 

 cured, and the inflammation of the eye considerably lessened. A fortnight 

 afterwards this also appeared to be cured. 



Case IV. A spaniel had been bitten by a large dog. There was no wound 

 of the lids, but the eye was protruded from the socket. I first tried whe- 

 ther it could be reduced by gentle pressure, but I could not accomplish it. 

 I then introduced the blunt end of a curved needle between the eye and 

 the lid ; and thus drawing up the lid with the right hand, while I pressed 

 gently on the eye with the left hand, I accomplished my object. I then 

 subtracted three ounces of blood and gave a physic-ball. On the following 

 day the eye was hot and red, with some tumefaction. The pupil was 

 moderately contracted, but was scarcely affected by any change of light. 

 The dog was sent home, with some extract of goulard, and a fortnight 

 afterwards was quite well. 



Case V. A dog received a violent blow on the right eye. Immediate 

 blindness occurred, or the dog could apparently just discern the difference 

 between light and darkness, but could not distinguish particular objects. 

 The pupil was expanded and immovable. A pink-coloured hue could 

 be perceived on looking earnestly into the eye. A seton was intro- 

 duced into the poll, kept there nearly a month, and often stimulated rather 

 sharply. General remedies of almost every kind were tried : depletion 

 was carried to its full extent, the electric fluid was had recourse to ; but at 

 the expiration of nine weeks the case was abandoned and the dog destroyed. 

 Permission to examine him was refused. 



I have, in two or three instances, witnessed decided cases of dropsy of 

 the eye, accumulation of fluid taking place in both the anterior and 

 posterior chambers of the eye ; there was also effusion of blood in the 

 chambers, but in one case only was there the slightest benefit produced 

 by the treatment adopted, and in that there was gradual absorption of the 

 effused fluid. 



About the same time there was another similar case. A pointer had 

 suddenly considerable opacity of one eye, without any known cause : the 

 other eye was not in the least degree affected. The dog had not been out 

 of the garden for more than a week. The eye was ordered to be fomented 

 with warm water. 



On the following day the inflammation had increased, and the adipose 

 matter was protruded at both the inner and outer canthus. The eye was 

 bathed frequently with a goulard lotion. On the fourth day the eyeball 

 was still more inflamed, and the projections at both canthi were increased. 

 A curved needle was passed through both eyes, and there was considerable 

 bleeding. On the following day the inflammation began to subside. At 

 the expiration of a week scarcely any disease remained, and the eye became 

 as transparent as ever. 



A curious case of congenital blindness was brought to my infirmary. 

 A female pointer puppy, eight weeks old, had both her eyes of their 

 natural size and formation, but the inner edge of the iris was strangely 

 diseased. The pupil was curiously four-cornered and very small. There 

 hung out of the pupil a grayish-white fibrous matter, which appeared to be 

 the remainder of the pupillary membrane.
