is to make the horse walk “groggy," as it is termed. He does not 
know what a “ cribbling" horse means. He never heard of the 
term : a crumbling horse in his going he, however, has often heard 
of — -but not cribbling — meaning, thereby, a horse whose action 
was imperfect. He does not step out freely. He saw the horse 
afterwards on the 23d of the same month. The lameness was 
then increasing. He was lamer on the second occasion. On the 
23d there was enlargement also, and heat and pain on pressure 
under the near knee. This seemed to be acute or fresh. 
He should term any deposition of bone on the small bones on the 
inside of the hock, spavin. The enlargement here was perceptible 
to every careful observer. It did not, however, make the horse 
lame, or apparently interfere with his action. He should think, 
from its size, that it had existed a considerable period of time. 
There was no inflammation or lameness now — no active deposition 
of bone now going forward. He would say that the deposition on 
the coronets was incurable, and it would require a considerable 
length of time both to have formed or to become partially absorbed. 
Re-examined. — Slight exercise, such as this horse had got, was 
very unlikely to produce inflammation. The morbid deposit of 
bone might be somewhat lessened by absorption, but it would never 
again become cartilaginous. When a spavin is forming, there is 
almost always lameness; but after the formation is completed, the 
lameness does not always continue. There was no lameness here, 
nevertheless the action would be somewhat impeded, and at some 
future time, in leaping or galloping, mischief might be done. The 
first cause of the affection in the fore feet might probably be inflam- 
mation of the navicular bone, or its synovial membrane. This 
would, in such feet, invariably produce contraction of the foot. He 
is not absolutely certain that this was the origin of the disease in 
the foot, but he is very much inclined to suspect it. There was too 
plain a chronic and tangible evidence of disease on the top of the 
coronets to make him doubt the soundness of the animal. Could not 
swear that navicular disease was present. Has no certain means 
of knowing, as he can neither see nor feel the seat of the disease, 
and, therefore, considered as the cause of lameness in this case 
the bony enlargements round the coronets, which he had the means 
of distinctly proving by the touch. These morbid enlargements were 
perfectly organized. 
Assistant Professor Spooner. — On the 15th of July he exa- 
mined a horse for Captain Martin. On seeing the horse, he recog- 
nised at once the existence of a spavin in the near hock. He did 
not give the animal a general examination, but confined himself to 
that on account of which the horse was brought to him — the lame- 
ness. He was lame in both fore legs, particularly the near one,
