lose every year from it. Among colts it has been very rare in 
this district until lately, but that may be caused by the few 
colts that have been raised until recently. It generally attacks 
them between birth and two weeks after, and I have noticed it 
in colts up to three and four years old, also in calves until they 
became yearlings, but the most fatal cases are those under two 
weeks. Having had a number of these cases lately I thought 
I would give a description and my treatment of same, which I 
would like my fellow veterinarians to comment on. 
On May 17 I was called to see a colt, a big, raw-boned two- 
year-old gelding, in very poor condition, rough, staring coat, 
and a profuse foetid diarrhoea, with capricious appetite, insati¬ 
able thirst, pulse fast, temperature ioo°, and respirations about 
normal. The colt had been in good condition until about a 
month previous, when he began to lose flesh, and for two weeks 
had been purging, and was so weak he went staggering all over 
the place. He had been running on grass, but I ordered him 
taken up and gave him a dose of oil of turpentine and linseed 
oil and ordered him fed on wheat bran, and powders of starch, 
chalk, and powdered opium every three hours. This seemed 
to have very little effect; so on the following day I gave him 
rectal injections of warm water and fluid extract of belladonna, 
and ordered powders of one-half dram of tannopine, given 
every hour. On the 20th he seemed better ; diarrhoea was less 
profuse, and not so bad smelling. On the evening of the 22d 
he passed a large quantity of worms, to which I attributed the 
cause of the diarrhoea. Four days after I saw him ; his coat 
was sleek, his spirits were high, and he seemed better than 
ever in his life. A few of the younger colts of the place had 
symptoms of the same, but were all checked by the same treat¬ 
ment before the disease had hold of them. 
Now, this is not the contagious form of diarrhoea, but as it 
is out of the ordinary run of cases, being caused by worms, I 
picked it out as a good subject. 
As to the contagious form : I was called to see a small roan 
colt at a farm where, although well fed, the stock was illy kept,
