JOINT LAMENESS IN COLTS. 601 
that suffer from it commonly give no evidence of the existence 
of the malady until after death. 
Treatment under such circumstances becomes very diffi¬ 
cult and unsatisfactory, and, indeed, cannot be conducted 
upon any general principles. A minute analysis of all the 
symptoms must precede a complete and correct diagnosis 
before remedies can be applied with a chance of success. 
With this view we propose to examine in detail the signs 
which the animal presents, and the conclusions to which 
those indications lead, selecting those symptoms which are 
characteristic, to the exclusion of many peculiarities of in¬ 
dividual cases, whose adduction would obscure the discussion, 
and compel a needless multiplication of examples. 
JOINT LAMENESS IN COLTS, ASSOCIATED WITH 
AND SYMPTOMATIC OF LUMBRICOID WORMS.

Such, perhaps, for want of a more correct term, I have 
named a disease I have occasionally for some years past 
been called upon to treat. I do so from practical observa¬ 
tions made during illness, also from post-mortem appearances 
of some animals that were the subjects of empirical treat¬ 
ment, and others which had been so long neglected as to 
defy medical aid, and, lastly, from a marked recent case, 
which, with your permission, I forward an account of for 
your Journal. 
I have found the cart-bred colts to suffer most. It generally 
occurs to those between the ages of nine months and two 
and a half years old. I do not recollect seeing an adult 
horse affected, and my youngest patient is the one I am 
about to record the history of. In the early part of August 
I was sent for to see a cart-colt, then sucking, about three 
months old. I found it very lame on the off hind pastern, 
with increased heat, sensitive to the touch, and a slight dis¬ 
charge from the heel. Some lotion was sent, and in a few 
days all appeared to be right, but about a week after I was 
again called in to see it. There was now extreme swelling, 
with pain and increased heat over the head of the femur of the 
same limb. Aperients were given, and a slight blister applied 
over the swelling; this continued for about three days, and
