128 DISEASE OF THE KIDNEY AND URETER IN A CALF. 
polypus was found hanging from the velum palati into the pha- 
rynx, greatly obstructing the elevation of the epiglottis and the 
passage of food. After performing tracheotomy to prevent suffo- 
cation, I passed a ligature around its pedicle, in the way sug- 
gested by the old anatomist Cheselden. 
A section of one of these tumours mostly displays several 
abscesses, with matter varying in consistency and often very 
foetid, enclosed in what seems to me to be fibro-cartilaginous 
cysts, the exterior of which sometimes gradually disappear in 
the surrounding more vascular abnormal growth. Osseous mat- 
ter (I judge from the grating of the scalpel upon it) occasion- 
ally enters into the composition of these cysts. 
I have treated this affection in cattle of the long-horned, short- 
horned, galloway, and highland breeds, and, from the number of 
bulls in this class of patients, have reason to conclude that they 
are more liable to it than the female. 
About twelve months ago I examined the head of a cow, on 
the right facial region of which there existed an enormous tumour, 
extending from the eye to the lips, and which I mistook during life 
for a periosteal enlargement. On cutting into it my mistake was 
evident. There was scarcely a trace of the original bones beneath 
the mass : even those forming the nasal sinuses on that side were 
replaced by a formation much resembling the cysts before al- 
luded to, and full of abscesses. The progress of the disease 
was decisively marked in the inferior rim of the orbital cavity, 
where the osseous matter was being removed, and the morbid 
structure deposited. 
DISEASE OF THE KIDNEY AND URETER IN A 
YEARLING CALF. 
By Mr. W. A. Cartwright, Whitchurch. 
On June 10, 1842, I was requested to attend a yearling calf 
that was a little unwell. There was not any thing to point out 
precisely the disease, and I therefore gave only a little aperient 
medicine. 
13th . — She is off her feed, and limps a little on her off hind 
leg, but the exact seat of lameness is obscure. The cow-man, 
about this time, discovered behind her, when she was lying 
down, a little coagulated blood. On voiding her urine it came 
dribbling away, and, at the conclusion, a very small quantity 
of coagulated blood was expelled. I continued giving aperient 
medicine for a few days.
