EXPANSIBILITY OF THE HORSE’S FOOT.

which is soon communicated to the rimas glottidis, or the larynx 
generally, and then the incessant and distressing cough. Ul¬ 
ceration takes place in the guttural pouch from the continued 
presence of the foreign body, and hence the purulent and foetid 
discharge from the nostrils. After a while, and no great while, 
adhesion takes place betw'een the ulcerated lips of the pouch, and, 
as our correspondent well describes it, the intruder becomes 
firmly covered and closed in, at least half an inch within the 
muscles and integuments of the parts, and no orifice remains.” 
As far as our limited experience goes, a cicatrix remains, although, . 
perhaps, not found without some little difficulty. 
Nothing but an operation of a serious and difficult nature will 
here avail, and which our correspondent will find described in 
page 396 of Cattle.

up to the good resolution he has formed. His name and abode —

ON THE EXPANSIBILITY OF THE HORSE’S FOOT, 
AND THE PRINCIPLES OF SHOEING. 
By Mr. J. Carlisle, Wigton, N. B. 
On reading the title of the first paper for discussion in the 
Veterinary Association this season, I was highly pleased to find 
a subject so important as the shoeing of horses ; an operation 
that stands high in the scale of veterinary science. I fully 
expected that the debate on so valuable a subject would have 
thrown some new light on the art, highly creditable to the 
veterinary surgeon, and truly valuable to the student. What a 
fine field was here open in an association like this, founded and 
governed by the first-rate practitioners in the land ! I fully 
expected something of universal estimation, but lo ! what a 
result! The old system of shoeing, with the addition of a lea¬ 
ther sole, is yet to predominate, and the expansibility of the foot 
and the descent of the sole to be completely denied ! I confess that 
this is strange doctrine tome ; and [ would ask. Are the functions 
of the foot to be utterly denied or destroyed ? Is the navicular 
bone neither to ascend nor descend? Are the highly elastic 
laminae to remain stationary, and the action of the lateral carti¬ 
lages to cease ? This must be the case if the expansibility of the 
foot is denied.
