LAMENESS IN HORSES.

time unrecorded. On this account, instead of giving any descrip¬ 
tion of it in general terms, we prefer narrating the cases we have 
registered. 
Case I.—On the 13th January, 1844, a troop horse was brought 
to us on account of lameness in the off fore limb. On the pre¬ 
vious day the horse had been sharply ridden in escorting her Ma¬ 
jesty from Windsor to Egham, and there was no doubt whatever 
that such had occasioned his lameness. There was heat about the 
fetlock joint, and fulness in the situation of the bursae at the back 
of it, and this heat extended down the pastern to the foot. The 
shoe was removed and left off for a couple of days, and the usual 
routine of bath and bandage and physic was adopted during the 
while. On the third day the shoe was replaced. Still the animal 
went lame. And now, on another examination of the leg, puffy 
tumours were discovered, one on either side, immediately beneath 
the sesamoid bones, reaching downwards and forwards to the ex¬ 
tent of a couple inches in the direction of the lateral processes sent 
off from the suspensory ligament. There was also a third puffy 
tumour, intermediate in situation between the lateral swellings, 
being an enlargement of the bursa occupying the interval left be¬ 
tween the divisions of the perforatus tendon for the issue of the 
perforans tendon. Between this- and the bursse at the sides 
there is evidently free communication ; for pressure upon the mid¬ 
dle bursa, below, immediately empties it, while it distends the 
bursse above; and pressure upon them reverses this effect The 
ordinary discutient lotion, with bandaging and pressure upon the 
tumours having been tried for several days without benefit, the ace- 
tum cantharidum was applied to them. This caused vesication, 
but not loss of cuticle or hair; and the result was restoration of 
the horse to soundness without any relapse thereafter. 
Case II. —The next is a case of enlargement of one of the same 
bursae without lameness. It is interesting from shewing how gra¬ 
dually, sometimes, bursae become enlarged. 
April, 1845, a troop-horse was brought into the infirmary stable 
for having a puffy tumour of the magnitude of the section of a 
large walnut, in the hollow of the heel of the hind leg. It was 
clearly a case of enlargement of the bursa between the perforatus 
and perforans tendons. The same horse was shewn me six weeks 
before for having a sort of pimply fulness in the same place; but at 
that time, there being no attendant lameness, I refused to admit him. 
It would, therefore, appear that the tumour must have been growing 
gradually since my attention was first called to it. The horse 
evinces no lameness from it. Still, on account of its magnitude, it 
being regarded as an eyesore, something must be done to get rid 
of it. The heel is a tender part to blister. And yet experience
