708 PLEUROPNEUMONIA AMONG CATTLE IN AUSTRALIA. 
coagulated lymph, in some of the cells amounting to half a 
pint. He advised Mr. Boadle to bury the beast, which was 
done. In three weeks after, another animal was seized with 
the same symptoms, and then a third. He regretted that 
Mr. Wragge was absent, as he had treated the affected ani¬ 
mals, and could have given more information on the subject. 
At the same time, in his mind there was no doubt about the 
disease. 
ee The Chairman then put the resolution, which was carried 
unanimouslv.

“ Mr. Stevens moved, and Mr. J. Thom seconded the next 
resolution, which was as follows: 
“ f That as the disease called pleuro-pneumonia, if allowed 
to spread, will be very disastrous to the colony, this meeting 
is of opinion that Mr. Boadle’s cattle should be purchased, 
for the purpose of being destroyed ; that a committee should 
be appointed to collect subscriptions to reimburse him, and 
see that the cattle are destroyed, with as little delay as possible.’ 
Mr. Pottie, a gentleman lately from Scotland, at the re¬ 
quest of the meeting gave the following information relative 
to pleuro-pneumonia. After stating that being en route for 
Sydney, he had onlv delayed his departure in order to be 
present at the meeting, he said that for many years he had 
been connected with the Highland and Agricultural Societv of 
Scotland, and had many opportunities of witnessing and 
studying the terrible malady called pleuro-pneumonia, which 
devastated a large portion of Great Britain. With reference 
to the morbid specimen upon the table, he entire coincided 
with Mr. Miscamble’s diagnosis. Besides pleuro-pneu¬ 
monia, however, there was another disease in one of them, 
viz., tuberculosis. After a few remarks upon the difference 
between contagion and infection, he said that any one who 
had seen anvthing of the disease, knew that it was commu- 
nicable from one animal to another; but it was not yet de¬ 
monstrated whether it was contagious or infectious, or both. 
For his part, he thought it was both, for he found that when 
cattle passed through a number of hands, the disease was 
most prevalent, and committed the greatest ravages. It was 
not difficult to tell bv auscultation whether a beast afflicted 
«/ 
with pleuro-pneumonia would recover or not. Percussion, 
too, was a good index. If a slight whistling sound was 
heard on applying the ear to the chest, the animal might re¬ 
cover. When that sound was absent, certain death ensued. 
Cows in calf were the least likely to recover. On one farm, 
where four cows took the disease in the first instance, three 
fourths of the herd died. On another of two cows, purchased
