PLEURO-PNEUMONIA AMONG CATTLE IN AUSTRALIA. 703 
services of Mr. Miscamble, who will furnish the results of 
his examination of the diseased animals. The next most 
important consideration was, the progress the disease had 
already made, as a rumour had transpired that it had mani¬ 
fested itself at some considerable distance from the herd 
originally affected. Our inquiries were, therefore, carefully 
directed to these points—the identity of the disorder with 
pleuro-pneumonia, and the locale of its appearance—because, 
taken in connexion, these must materially affect and indicate 
the preventive or precautionary measures necessary to be 
adopted. We have, however, furthermore been able to 
ascertain the history and progress of the disease in the herd 
(Mr. Boaale’s) so seriously affected, and we have every 
reason to suppose this information will afford a clue to the 
origin of the distemper in the colony. 
te e We, in the first place, proceeded to the neighbourhood 
in which rumour had assigned the second appearance of the 
disease, and there ascertained the circumstances which had 
given rise to the report. These, however, in no way justi¬ 
fied the alarm, which may be considered incidental, and 
attributable to the general feeling of uneasiness in the dis¬ 
trict, where the fatality in Mr. Boadle’s herd was well known. 
It appears that a cow r died on the farm, a distance of eight 
miles from the diseased herd, two months ago, and a second 
was ill on the occasion of our visit. This latter animal w*e 
saw, and have no hesitation in expressing our conviction that 
her disorder bears no resemblance to pleuro-pneumonia. 
The fear, therefore, that the infection had spread to the 
neighbourhood in question, is at present without founda¬ 
tion. 
“ ‘ On visiting Mr. Boadle’s farm we found that his cattle 
were divided into two lots—one comprising cattle then in 
good health, and a second composed of diseased and sus¬ 
pected animals. In the latter there were at the time of our 
inspection ten beasts in different stages of the disease, and 
we certainly feel bound to state that even a cursory glance 
will establish the identity of the malady with pleuro-pneu¬ 
monia. We had, however, one of the animals slaughtered, 
but as Mr. Miscamble will more properly describe the post¬ 
mortem appearances, it is unnecessary for us to refer particu¬ 
larly to the corroborative evidence thereby afforded, further 
than to state that the left lung was a mass of putrid matter, 
and that the inflammation also extended to the right lung. 
<£ f To Mr. Boadle we are indebted for the following his- 
torv of the attack, and the circumstances connected there- 
with. The first case occurred in an imported cow, landed in
