PURPURA HEMORRHAGICA, 
399 
On my next visit (the 7th) I found the mare much better. 
The swellings were lessened, and the respiration and pulse 
more natural. The urine had acquired its natural appearance, 
and the quantity was increased ; but there was a good deal of 
irritation existing about the bladder, so much so as to make 
me resolve to discontinue the draught, and to substitute for 
it the iodide of iron in combination with a milder diuretic. 
On visiting my patient again on the evening of the next 
day (8th), a sad change for the worse was observed; the 
' swelling had increased in the fore limbs and chest, and 
the head was now involved, so much so as to interfere con¬ 
siderably wdth the breathing; the mucous membrane, as 
much of it as could be seen, was covered with scarlet spots, 
some of which were in a sloughing condition, and a nasty un¬ 
healthy discharge came from the nostril. The mare now can 
scarcely move, and the respiration is performed with diffi¬ 
culty. The urine has again become scanty, and has resumed 
its discoloured appearance. 
The owner attributed her relapse to a discontinuance of the 
draughts, stating that, in a few hours after the last was given, 
the swelling of the head and chest began, and continued to 
increase up to the time I saw her. E/cpeat the turpentine 
draught, giving it three times in the day. 
The day following she was much the same, or if anything 
a little better. 
On the 10th there was a still further improvement percep¬ 
tible ; the swelling had now left the limbs, and located itself 
principally in the breast and abdomen. The mare can walk 
comfortably, and the enlargement has so far left the head as 
to enable her to breathe with comparative ease. The urine 
has also again become plentiful, but she makes constant 
efforts to urinate, and her mouth is so much excoriated by 
the turpentine, that I am again tempted to lessen the 
draughts to one a day, and substitute the balls containing 
the iodide of iron. 
11th.—The mare is again worse, and the most unfavorable 
symptoms are evidently returning, so that we were compelled 
to return to the draughts again, which seem to have an im¬ 
mediate good.effect. 
From this time the animal rapidly recovered, the disease 
leaving no ill effects except a little sloughing of the skin of 
the heels of the hind legs. 
Case 2.—On the 15th of April, 1863, I was requested to see 
a two-year-old mare, the property of an innkeeper in this town. 
Upon inquiry, I ascertained that she had recently had an
