CANINE PATHOLOGY 
405 
Making a careful examination, niuoii conjunctivitis of the 
right eye was present, photophobia well marked, the membrana 
nietitans protruding slightly, reddened, and somewhat swollen. 
When left to himself, the animal would rub the eye vigorously 
with his paws, seemingly in an agony of pain, uttering sharp 
cries the while. 
Examining the eye again, nothing was at first observed that 
would give rise to such severe irritation. At last, separating the 
lids, and making pressure on the globe to develop further the 
membrana nietitans, a minute black speck was noticed, which 
disappeared when pressure was relaxed. This was seized with a 
fine pair of forceps, and much to our surprise a small porcupine 
quill, about half an inch long, was drawn out. From this time 
forward the patient did well. 
Case No. 5 — Removal of Dislocated Lens , or Floating Cata¬ 
ract .—This patient, a well-bred pug, about four years old, was 
sent to the infirmary with the following history : Was the prop¬ 
erty of a lady, and was reported to have been in a like condition 
for a year, the time she had owned him ; had observed something 
floating in the left eye, and at times thought the dog was blind in 
that eye. Sometimes the eye would appear perfectly clear; at 
others noticed a white body covering the pupil. 
A diagnosis was made of dislocated lens, and after consulta¬ 
tion with Dr. Benoit, an operaf m was advised and consented to. 
The animal was prepared by dieting, and a solution of atropia 
sulph., gr. J to oz.i water, applied for two days. 
The operation was performed under the influence of ether, 
and consisted in removing the lens by a hook, through an open¬ 
ing made at the superior margin of the cornea with a Bead knife. 
A compress of cold water was applied over the eye, and the same 
solution of atropine used for several days. 
The wound healed kindly, and the eye, when examined by 
the ophthalmoscope, showed the retinal vessels and entrance of 
the optic nerve very plainly. The pupil responded freely and 
promptly to the influence of light. 
The lens enclosed in its capsule was firm in consistency, and 
opaque; the capsule was semi-opaque on its anterior and posterior 
surfaces.
