556 CONTRIBUTIONS TO THE PATHOLOG if AND 
patches of a lighter shade of green; and at the junction of the 
ileum with the caecum was a large deposit of carbonaceous matter. 
Urinary Organs. — The kidneys were pale in colour, but firm in 
their structure ; the ureters were healthy. The mucous membrane 
of the bladder was covered with dark red and scarlet spots. The 
urethra was normal. 
Respiratory Organs. — The Schneiderian membrane was of one 
uniform dull red colour ; the redness extended to the larynx. The 
mucous membrane of the larynx presented several patches of a 
green colour : the same with respect to the mucous membrane of 
the trachea, in which were intermixed blood spots. The bronchial 
tubes were all gangrenous, at least all that I examined. A large 
portion of the left lung, on being cut into, I found was scirrhous ; 
other portions were softened. The lungs throughout did not cre- 
pitate, and a frothy serum exuded on the withdrawal of the knife. 
The right lung was in a very similar state, though not so exten- 
sively diseased. The pleura pulmonalis had a few red spots upon 
it. The pleura costalis was normal throughout. 
Organs of Circulation. — The heart was sound in its structure, 
but pale in colour : the thickest portion of the walls of the left ven- 
tricle was one inch and three quarters, and that of the right ven- 
tricle was a little more than three quarters of an inch. The weight 
of the heart, when divested of its fat and large vessels, was exactly 
seven pounds twelve ounces avoirdupois. The large bloodvessels 
were all healthy. 
Brain , 8jc. — The brain and its membranes were firm in texture, 
but bloodless : the spinal cord the same. The large nerves I did 
not examine. 
Skin. — The skin, in those places covering the swellings, ap- 
peared thickened, and it readily separated into layers; and between 
these layers was a thin bloody serum, which copiously exuded 
when I squeezed the skin. The skin was not broken through in 
any part. 
Case Y. 
April Mh, 1849. — I was requested, about four o’clock, P.M., to 
attend upon a mare, the property of Messrs. J. R. & Co., manu- 
facturers, in this town. 
History, 8$c. — The mare in question is of a dark brown colour, is 
half bred, stands exactly sixteen hands high, and is now six years 
of age. She has been the property of the firm two years less about 
four weeks. She was bred by a farmer who resides about eight 
miles from Huddersfield ; and, from having known her for some
