OSSEOUS TUMOUR OF THE IIOCK.

ceased. Since then she has been able to get some grass, 
and is fast regaining her condition. The mammary gland is, 
however, more distended than it has ever been, and the 
quantity of milk is much greater. 
These cases are not common; I have known two, in both 
of which, however, the milk was only small in quantity, and 
did not continue long. These fillies belonged to a Mr. 
Pocock, of this neighbourhood. I find that there are two or 
three cases reported in the Veterinarian of the same kind as 
this. 
[An examination of the milk, both chemically and micro¬ 
scopically, showed that it differed in no essential particulars 
from milk yielded by animals under ordinary circumstances.] 
CASE OF OSSEOUS TUMOUR ATTACHED TO THE 
INNER AND FRONT PART OF THE HOCK.— 
OPERATION. 
By the Same. 
THE^accompanying tumour was dissected from the hock, at 
the seat of bog-spavin, of an aged bay cob-gelding, fourteen 
hands two inches high, belonging to Walter Long, Esq., M.P., 
who had a year previously refused 180 guineas for him. The 
enlargement had been increasing in size, notwithstanding the 
repeated applications of iodine ointment for nearly twelve 
months previous to my seeing the animal. It was loosely 
attached to the capsular ligament, although it did not interfere 
much with the action of the hock; but I nevertheless con¬ 
sidered that there was much danger of wounding the capsular 
ligament in the operation of removing it. I also feared an 
unfavorable result from subsequent sloughing. 
The operation was performed on the 24th November, 
1863, and the subsequent treatment consisted in the applica¬ 
tion of cold water only. The edges of the wound required 
to be occasionally touched with caustic. In about a month 
the animal was daily exercised, and on the 14th January he 
was ridden home, a distance of fourteen miles. 
I have not seen the animal since that time, but have been 
informed by the groom that the edges of the wound are quite 
closed, and that the case went on most satisfactorily from the 
time the animal left my infirmary. 
[The tumour was spheroidal in form and about the size of 
an orange.]
