flammation of the eye, nor opacity of cornea, followed. In a 
few days the organ seemed to have quite recovered its natural 
form and size; and, as far as could be ascertained, vision 
remained unimpaired. 
Polypus in the Prepuce of a Dog. 
The subject of this affection is a rough Scotch terrier. His 
master had perceived for several weeks prior to his bringing 
him to me—which was on the 4th Sept. 1851—a sero-purulent 
discharge, sometimes tinged with blood, issuing from the 
sheath, which he attributed to the effects of excess of or impure 
coition, or to some such cause, until recently, when, upon 
further examination, he discovered some unusual substance 
therein. This he desired to have my advice upon. 
An examination, by turning back the sheath as far as prac¬ 
ticable, disclosed the presence of a polypus, of a soft sar¬ 
comatous character, in substance about half the bulk of one’s 
little finger, and somewhat longer, as it appeared to me by 
tracing it on the outside of the sheath with the fingers up to its 
origin near the commencement of the perinaeum. 
It was too soft and easy to be broken to attempt its ex¬ 
traction with forceps, and its root was too far backwards to 
make a ligature available. A longitudinal incision w’as made 
along the inferior border of the sheath, extending from the 
perinseum, posteriorly, to within a short distance of its natural 
orifice anteriorly. This exposed the interior of the prepuce, 
and enabled me to get at its attachments, which were broad 
and found to be to the mucous membrane covering the root of 
the penis, upon its lower surface, enclosing about one-half 
of its circumference. The polypus extended forwards, un¬ 
attached, from this' point to nearly the other extremity of the 
sheath, having somewhat the appearance of a bundle of small 
earthworms, but much less firm, connected together by delicate 
tissue. There were also two other small fungoid-looking ex¬ 
crescences, about the size of split peas, distinct from each other, 
attached to the mucous membrane lining this passage. They 
were all carefully removed with the scalpel, and the places 
touched with argent, nit. The wound was afterwards drawn 
together by sutures, and a muzzle put on the dog. 
So far, all went on satisfactorily. Not quite so, however, the 
healing process; for we had here to contend with three for¬ 
midable obstacles to it.
