98 PLEUltO-PNEUMONIA AMONG CATTLE IN AUSTRALIA. 
"withstanding the severity of the disease indicated by these 
appearances, the animal was not only not in an emaciated 
state, but, on the contrary, was in tolerable condition. 
“ Case 2. — This case was selected as one of the worst 
affected. He was in an emaciated condition. A working- 
bullock, about ten years old. Appearances.—The left lung was 
wholly hepatized, and in bulk occupied a space three times 
its natural size; the coats of the vessels were in the same 
condition as those described in the first case. The right 
lung, as in the first case, was slightly inflamed. The left 
pleura had similar lymphatic effusions attaching the lung to 
the pleura costalis in its entirety. The lymph was in con¬ 
siderable quantities, and of a consistency easily broken down 
by the finger. The pleura costalis on the right side was 
slightly covered with separated patches of lymph. The 
trachea same as first case. The heart, its serous covering 
and pericardium, similar to first case. The abdominal viscera 
were normal, except the liver, which was unusually small in 
proportion to the size of the animal. The spleen was as in 
the first case. 
i( Case 3.—This was the worst case of all. A seven-year- 
old milch cow, with all the appearances of Case No. 2, but 
in a more aggravated form, even to having the right lung 
hepatized in its centre, the impervious structure of which 
was about six inches bv eight inches in its dimensions. The 
left lung was so large as almost completely to fill its cavity, 
with the exception of the portion between it and the dia¬ 
phragm, which was filled with about two gallons of serum 
mixed with red particles of blood, and was firmly attached 
to the diaphragm throughout a considerable extent. The 
heart and its appendages were the same as the others, ex¬ 
cepting on the serous membrane. On the apex of the heart 
were projecting bands of lymph hanging towards others of 
a similar nature from the adjacent like structure of the peri¬ 
cardium, threatening (were union possible) to arrest the 
action of the heart. 
“ Case 4.—This last case was one said to have recovered 
from the disease three months ago, but which was stated not 
to have been in a thriving state previously to her illness. A 
vast number of tubercles were formed on the lungs and 
pleurae, pendulously attached by serous membranes, while 
others were embedded in the structure of the lung. Similar 
deposits were found in other parts of the body of the same 
size—viz., from the size of a walnut to a goose egg, flattened
