thought, possibly, that of the superficial flexor, as I could feel on 
rotating the foot, that the’deep one appeared all right. 
The owner was advised to have the animal destroyed, which 
was done, and the lower part of the leg secured for dissection, and, 
as arranged, left it at Dr. Kemp’s office, stating I would return, 
but before I could do so, I found his anxiety had saved me the 
trouble, so that I have'to give the result of the post-mortem in 
his own notes, taken at the time, which are as follows: 
“ Upon examination of the foot of the black horse, I find the 
trouble due to a separation of the glenoidal fibro-cartilage, which 
completes the superior articular surface of the os coronse posterior¬ 
ly, from its point of attachment to that bone. It is completely torn 
away from its place of insertion, and lias taken with it the perios¬ 
teum and superficial layer of the bone, leaving the cancellated 
structure exposed. 
As this fibro-cartilage-serves as a means of attachment to the 
superior superficial sesamoid ligament, and also acts itself as a 
powerful posterior ligament, sending several fibrous bands to the 
first phalanx, the severity of the injury is apparent. The syno¬ 
vial bursse of the joint are much distended, and contain a large 
amount of bloody synovia.” It will be seen that he makes no 
mention as to how lie found the inferior attachment of the super¬ 
ficial flexor, but when I made enquiry on this point, he stated he 
could not remember. On looking at the specimen before me, I 
feel there was a possibility of its having given way. 
OBSTRUCTION OF STERNO’S DUCT-OPERATION-RECOVERY. 
By Wm. R. Howe, Y.S. 
On the 20th of May-I was called by a veterinary practi¬ 
tioner of this city to see a case which he said bothered him. I 
found a grey mare about seven years old with right parotid 
gland somewhat enlarged, and the duct of Steno, from the gland 
down, much enlarged. Where it rounded the angle of the jaw, 
it formed a dependent sac, but from there to what should be the 
outlet, no enlargement. After considerable manipulation I
