PLEURO-PNEUMONIA AMONG CATTLE IN AUSTRALIA. 705 
ee e In justice to Mr. Boadle, we feel called upon to state 
that we attribute this hopeful feature of the case to the 
course he has pursued in reference to his herd. His neigh¬ 
bours were cautioned, and the greatest precautions were used to 
prevent contact or admixture. Had a mercenary course been 
pursued, the stock sold and dispersed, the results must have, 
long ere this, seriously affected the colony at large.

<( Mr. Miscamble being called upon, stated that there was 
in his mind no doubt whatever about the disease amongst 
Mr. Boadle’s cattle being the much-dreaded pleuro-pneu- 
monia. He, with the gentlemen forming the committee, took 
one of the worst cases on the farm, and another which was 
considered to have been cured, and Mr. Boadle allowed the 
animals to be slaughtered at their request. He (Mr. Mis¬ 
camble) found in the first beast that the left lung was hepa- 
tised, or solidified, and covered with adhesive lymph, which 
fixed it to the chest. He also found two gallons of serum in 
the cavity, and one of the lungs firmly fixed to the dia¬ 
phragm. The serous membranes generally were also consi¬ 
derably affected. In the animal supposed to have been 
cured, there were tubercles in several clusters lining both 
sides of the chest, and in the superior mediastinum a large 
tumour full of curded lymph, which seemed to have existed 
a considerable time, as the walls of the abscess were quite 
tough. He had brought samples, both of the acute and 
chronic condition of the lung, and had no doubt whatever 
as to the nature of the disease, or as to its origin, which 
was certainly attributable to the fact, that an imported 
heifer suffering from the malady had been introduced into the 
herd of Mr. Boadle. 
“ The Chairman thought that after the very clear state¬ 
ments which had been made, prompt action should be taken 
to prevent the disease spreading. He might mention, that 
in the course of one of his importations of cows and horses 
from England, one cow died of pleuro-pneumonia before 
being shipped, and four horses died on board of the same 
disease. Three of them died in two days, and one in three. 
In the latter case the lungs were completely absorbed, and 
the cavity of the chest contained one mass of corruption. 
u Mr. Miscamble thought the disease was only met with 
in cows, and not in horses. The seat of disease might be 
the same, and yet the disease be widely different.
