PLEURO-PNEUMONIA IN AUSTRALIA, 
351 
centuries epizootic pneumonia has ravaged the herds of 
various states. An account of a species of pneumonia min¬ 
gled with pleurisy was published in 1833 by M. Lecoq, of 
the Veterinary School of Lyons, which describes general 
symptoms precisely similar to those of the disease which at 
present prevails here. Analogous diseases have occasionally 
made their appearance in the United Kingdom ; but for up¬ 
wards of twenty years past the malady, now known as pleuro¬ 
pneumonia, has from time to time been raging with great 
intensity and destroying vast numbers of cattle there. 
It was first introduced into the colony of Victoria about 
three years ago, by a cow imported from England by Mr. 
Boadle; and has been traced from her to the borders of New 
South Wales. 
With pleuro-pneumonia in our immediate neighbourhood, 
prompt and vigorous measures became necessary to prevent 
its introduction into this colony; and an Act w 7 as passed by 
the legislature, in the month of April last, with that object 
in view. This was unquestionably a commendable course to 
pursue; but, without inspectors to guard the Murray boun¬ 
dary, itw r as utterly impossible effectually to hinder its viola¬ 
tion. Large numbers of store cattle were taken into Victoria 
from New South Wales, and every one acquainted with the 
habits of cattle knows with what pertinacity they seek to 
return to their old runs. The Murray River would be but a 
slight obstacle to the gratification of this instinctive desire, 
and it is now certain that cattle crossed in considerable num¬ 
bers. At the time the proclamation under the Act was pro¬ 
mulgated there were many bullock teams on their way to New 
South Wales from Melbourne with goods. It is a well-known 
fact that many of these teams were left on the other side, and 
the drays were brought across; but it is also a well-known 
fact that the bullocks diaappeared quickly from the south 
side of the river, and the drays as quickly vanished from 
Albury. There cannot be a question but that the law has 
been evaded, and that bullocks have been brought over, and 
the drays and loading removed, during the night-time. It is 
estimated that some hundreds of bullocks have been brought 
over in this way, and it is likely enough that they have been 
instrumental in disseminating the disease in this colony. 
The first appearance of pleuro-pneumonia in New South 
Wales was in the herd of the Messrs. M‘Laurin, of Yarra 
Yarra, at the head of the Billy Bong Creek, about the begin¬ 
ning of August last. It was said that this herd was infected 
by a number of store cattle brought by these gentlemen upon 
that station in the month of February last, from the Mitta
