CASE OF DIARRHCEA IN A COW.—POST- 
MORTEM APPEARANCES. 
By the Same. 
In May last I was called to attend a cow, in the village, 
described as suffering from the above disease, and such on 
my arrival I found to be the case. The alvine evacuations 
were profuse, and accompanied with much fcetor. I there¬

sulphate of magnesia, half a pint of linseed oil, in conjunction 
with one and a half ounces of ethereal tincture of opium. 
The next day the owner called to say that the cow was 
down, and voiding large quantities of blood, which proved to 
be the case. I ordered the ammonio-sulphate of copper 
to be given, but before the owner could administer it the 
animal died. 
Autopsy .—Reticulum ecchymosed; omasum in the same 
state, as were also the abomasum and the small and large 
intestines. 
The heart .—The left auricle, and right and left ventricles, 
of a Modena-red colour; the right auricle pallid; the in¬ 
terior ecchymosed in spots; the pleura pulmonalis slightly 
inflamed. 
On my first visit, I could hear the heart beating violently 
against the ribs ; but the owner telling me that she was, when 
well, a very excitable animal, lulled my suspicions respecting 
the heart being affected. 
VETERINARY OBSTETRICS. 
By A. C alley, Kirkton-by-Burntisland. 
Gentlemen, —I feel much obliged to you for inserting 
in the Veterinarian of June my letter relative to Mr. Gamgee’s 
first remarks on my case of “ A Mare destroyed from 
difficult foaling.” But as he has thought fit to renew his 
attack upon me in a lengthened article which appears in the 
same number of your journal, I feel myself called upon, not 
less in self-defence, than for the sake of truth and justice 
and the interest of veterinary science, to claim a parting word 
in reply, which I entertain the hope you will do me the
