hagica, in which he, after referring to the symptomatology, spoke 
of the causes, in his experience, as always being the working of 
horses after an attack of influenza before they were convalescent, 
or in cases where they were not properly treated for that disease 
and where the drainage and ventilation of the stable was bad. He 
described the post mortem lesions of purpura, and then gave his 
plan of treatment as follows : 
“ I have had very good success with the use of iodide of po¬ 
tassium in combination with sulphate of iron, which I gave in 
drachm doses of each, twice daily. I also gave whiskey in pint 
doses three times a day in a pail of cold water, which the animal 
will drink with a relish. To each of these doses may be added 
one half ounce of both chlorate of potassium and nitrate of potas¬ 
sium. If the swelling appears on the head I apply comp, tinct. 
of iodine every three or four hours, which has a most wonderful 
effect in reducing the enlargement. The nose ought to be sponged 
out at least every hour with tepid water, to which has been added 
a little salt. When the animal begins to convalesce, tonics are 
necessary. I have found iron combined with arsenious acid the 
best; say one-half drachm of the former to three grains of the 
latter, twice daily. Sloughing is very frequent in purpura he¬ 
morrhagica. I have had cases where the flesh actually dropped off 
in chunks, and in one particular case all the muscles inside of 
the near hind leg came away, exposing the femur. A mild 
solution of carbolic acid I have found the best dressing, or 
when the healing process is obstinate, a solution of nitrate of 
silver may be applied occasionally with good results. 
A very bad form of this disease is where the animal has a 
sore throat, and has difficulty in swallowing. In such cases I have 
the throat swabbed out with a sponge dipped into a saturated 
solution of chlorate of potassium three or four times a day. With 
regards to the animal’s diet, I allow him to have whatever he will 
eat, and prefer him to have the most nourishing food in the 
smallest compass. When the animal refuses all food, I And 
the whiskey drink of the greatest value, as it not only nour¬ 
ishes the animal, but promotes an appetite.” 
In the discussion that followed, Hr. Cochran stated that he
