PHRENITIS IN CALVES. 
of the animal shows that she cannot possibly survive much 
longer ; at half-past nine she died. This case lived about 
twenty-three hours after she first showed symptoms of being 
unwell. 
Post-mortem Examination — Abdominal Cavity. — Contents 
of the third stomach hard ; the small intestines show traces of 
slight inflammatory action. The rectum is considerably in- 
flamed for about six or eight inches from the anal opening, 
as is also the vagina ; the liver, spleen, kidneys, bladder, and 
uterus are healthy. 
The whole of the contents of the thorax healthy. 
The vessels of the brain were somewhat distended, but l 
was unable to detect anything like disease. Mr. Cooper, of 
Berkhampstead, assisted me in the post-mortem examination, 
and we were very particular, as rumours were current, that 
the animal had been maliciously injured ; such, however, was 
not the case ; in fact, the only indication of disease that wewere 
able to detect was a hardened condition of the contents of the 
third stomach, and inflammatory action existing in the last 
portion of the rectum and vagina, but not in any way sufficient 
to cause death in so short a space of time ; no poisonous herbs 
could be detected in the pastures that the cow had been 
grazing in ; and two others that were with them have escaped. 
Can you throw any light upon these cases, as we are at 
present unable to assign a cause for so unusual an occurrence, 
further than conjecture that they have been poisoned either 
by what they have eaten or drunk ; unfortunately, the con- 
tents of the stomach have not been analysed. The post- 
mortem appearances in all the cases were nearly alike. 
I am, sir, yours obediently.

Sir, — If you think the following worthy a place in your 
aluable periodical, it is at your service. 
On the 29th ult. I was called to Mr. W. Anson’s, of Fair 
Oaks, near Selby, Yorkshire. On my arrival, I found nine 
yearling calves dead, and two labouring under that dreadful 
disease, phrenitis. 
Treatment , — Venesection to fainting; gave to each half a 
pound of Mag. Sulph., and one scruple of the farina of the
