DISEASED LUNGS OF A HORSE. 
quantity of dark fluid blood. The pleurae pulmonalis and 
costalis were healthy; the lungs, which were of an enormous 
size, and weighed 50 lbs., bore a remarkable and striking 
appearance; they resembled in touch that of liver, and 
were consolidated, having small patches (triangularly shaped) 
of a fatty nature permeating the whole substance of the 
parenchyma. The near or left lung, on which side the 
animal died, was of a dark colour, the off having a light flesh- 
coloured appearance; the bronchial tubes contained a small 
quantity of sanguineous mucus.

REMARKS BY PROEESSOR VARNELL. 
The above is one of the most interesting cases of disease 
of the lungs I have ever met with, and, as far as I can 
discover, it stands alone in English veterinary literature. I 
think I may safely state that this is the opinion also of my 
colleagues. The morbid specimen was shown to some of the 
most eminent pathologists in London, who considered it to 
be almost unique. This makes the case the more inter¬ 
esting, and places me under great obligation to Mr. South 
for the opportunity he has given me to investigate it. 
With only a little difference, both the lungs presented the 
same morbid appearance; they were, as nearly as possible, of 
equal size, although much larger than natural, and, as 
remarked by Mr. South, one was darker in colour than the 
other, which, no doubt, was due to the position the horse was 
in at the time he died, and also in which the carcass remained 
for some time after death. In consistence they were firm 
«/ 
but springy to the feel, except at the posterior and anterior 
extremities of both the large and small lobes, where they 
were soft and spongy, and much lighter in colour. The 
pleural coverings were, with the exception of being in some 
places slightly thickened, but little altered in character. 
In making a section through the lungs in a longitudinal 
direction, a better idea could be formed of the extent of the 
disease, which to me, I must confess, was very remarkable. 
With the exception of one lung being a little darker in 
colour than the other, as was noticed with regard to their 
outer surfaces, the interior was very similar in appearance. 
The cut surfaces of the sections of these organs were of a 
pale-red colour, thickly studded with whitish spots about the 
size of a pea; some of them, however, were much smaller. 
They varied in colour from yellowish to a pearly white, the
