ON THE PRESENT EPIDEMIC AMONG CATTLE. 591 
We may, perhaps, obtain considerable information from care- 
ful observation of the appearances after death. Whatever may 
be the case with regard to the cure of this disease, I do conceive 
that I have learned something from the examination of the ani- 
mal that was so promptly given up by the owner. 
The disease was entirely confined to the chest. The left lobe 
of the lung was immensely enlarged, and when cut into had an 
appearance similar to what is called marled beef, and about the 
same consistence. This appearance was produced by effusion 
of lymph within the substance of the lung, and, when a portion 
was pressed in the hand, a very considerable quantity of serum 
exuded. The lung had not that great hardness and solidity of 
which Mr. Barlow speaks; but, as the farmer said, the cow would 
have lived two or three days longer, and this might have increased 
the condensation of the lungs. 
The right lobe of the lung shewed little if any disease, but ap- 
peared as if it were compressed. 
There was effusion in* the pericardium, and considerable adhe- 
sions of the pleura. 
The bowels and the kidneys performed their functions during 
the whole course of the complaint. 
The post-mortem examination being completed, and the whole 
history of the different cases given, so far as they could be ob- 
tained, then came the important but difficult duty of advice as to 
the future management of those that were already diseased, or 
might soon become so. 
I advised that all that had the husk should at once be put un- 
der treatment ; that setons should be extensively inserted in the 
chest, and fever medicine, consisting of pulv. digital, et antim. 
tart., should be given to one portion of the cattle ; the calomel and 
opium, as recommended by Mr. Barlow, to another set, and the 
iodide of potassium in doses of half a drachm twice in the day 
to the rest, and, with regard to a portion or all of them, combina- 
tions of these with any other medicine that circumstances might 
indicate. 
I urged that those who were affected should be kept perfectly 
at rest in a cowhouse well ventilated, and that setons should be 
made use of in every case that indicated disease or danger. 
I have had the satisfaction of hearing that, although several 
fresh cases occurred, not a single cow has been lost since the one 
that was killed for my inspection, and that most of those which 
I saw may be considered as recovering. If any thing of import- 
ance should occur, I shall feel it my duty to communicate it to 
you.
