the wheel occurred, the extensor tendon, which is in close 
contiguity with the bone, lost a few shreds from the same 
violence — the tendon exhibiting a small rough notch. 
Second Case. — About two years subsequently to the occur- 
rence of the above case, a very valuable blood carriage horse, 
the property of Mr. Joshua East, the eminent Jobmaster, 
met with the following accident: the animal was in high 
condition in a gentleman’s job at New Cross. He got cast 
in his stall, and in his struggle broke the iron grating of 
the drain with his hind foot, which suffered severe contusion, 
with laceration of the integuments of the coronet, and slight 
ligamentous exposure. The lameness was considerable, and 
the pain acute, and in this state he was unfortunately led up 
to London. 
I was called in immediately, but the seven miles’ journey 
to Lamb’s Conduit Street, had added so great a shock to the 
system, that the case was rendered unmanageable, and all 
my various soothing applications were set at defiance. Symp- 
tomatic fever increased daily, accompanied with almost per- 
petual sweating from intensity of pain in the injured limb, 
until tetanic symptoms suddenly appeared about the tenth 
day. The jaws soon became immovable, and upon the head 
being raised, the eye was completely hidden by the membrana 
nictitans. The animal died within twenty-four hours of this 
attack of locked-jaw. 
Post-mortem Examination. — The tumefaction of the limb 
very moderate; the coronary ligament was bare at the inner 
front of the coronet, just above the hoof, for about an inchin 
length, and half an inch in width ; the capsular ligament was 
quite entire, not having been penetrated. Upon opening the 
coffin-joint there was a complete absence of synovia, and the 
synovial membrane appeared in the highest possible state of 
inflammation ; no fluid could be found in the cavity of this 
large joint. I could not, by the unassisted eye, trace any 
disease of the nervous tissues or trunks of the injured limb. 
Upon examination of the vascular trunks, arteries, and 
veins, from the hoof to the hock, they were found unob- 
structed and completely pervious throughout, except the 
inner trunk of the pastern artery , ivliich was obliterated through 
its whole length , from the hoof to the fetlock joint , the plug or 
obstructing medium was a white dense fibrinous clot firmly adherent 
to the lining coat of the artery. The organization of the other 
coats of this artery appeared perfectly normal.
