ON THE EPIZOOTIC DISEASES OF CATTLE. 
tops (they could not eat turnips) and hay, with plenty of linseed- 
cake gruel. Some of them are very lame, after being attacked 
from thirty to forty hours. Repeat the tonic draught daily, ex- 
cepting where the animal appears more than usually dull and 
constipated ; then give one of the aperient draughts with a pint of 
linseed oil. 
They were all going on well — getting out of hand with about 
four doses each, until Nov. 25th, when a small heifer was off 
her food — very dull — eyes contracted within the orbits — fre- 
quently down, and appearing very low and weak. She dungs, 
but not freely — she is suffering from indigestion and constipa- 
tion. Treated her by stimulants, linseed oil, and aperients. 
Upon examination of her faeces, they present the usual appear- 
ance ; but when crushed are found to be made up of a complete 
mass of reddish dark sand. She continued to get worse until 
Nov. 27th, when she died. 
Upon a post-mortem examination, the small intestines were 
found inflamed and contained a great quantity of dung, princi- 
pally sand, as if mixed into pellets with some adhesive moisture. 
The abomasum was filled with a fluid of the consistence of cream ; 
it also contained a great deal of sand. The stomach was healthy, 
but full of half-masticated food. She had been on the farm about 
twenty days. 
On the day on which she died, a good milch cow appeared 
similarly affected. She discharged a great quantity of saliva 
from her mouth. Her principal employment consisted in sucking 
the saliva from the bottom of the manger. The bowels were at 
first constipated, but in about thirty hours afterwards she began 
to purge, but did not appear relieved. She continued to gra- 
dually sink until Dec. 2, when she died. Two days previously 
the discharge from her mouth had ceased, and she would drink 
gruel. 
The post-mortem examination did not differ much from what 
was generally presented in such cases ; — full stomach, tenderness 
of the lining membranes, inflammation of the small intes- 
tines, &c. 
Three other milk cows were also very ill — off their food — dis- 
inclined to move — loss of cud — bowels inclined to be costive — 
pulse weak — horns and extremities rather cold. In a few days 
they recovered, by treating as for indigestion. The whole of 
these fine animals had the disease to appearance favourably, 
when, about the fourth or fifth day, they appeared to be taken 
worse. I should, however, certainly say that dyspepsia seems 
to be one of the terminations of the disease.
