PRACTICE OF VETERINARY MEDICINE.

small and large bowels, was pale in colour; the external surface of 
the stomach presented a pale pea-green tint: its muscular tunic 
was easily lacerated. This was the case with the coats of the 
bowels also; a very gentle force sufficed to tear them in pieces. 
The liver was moderately sound, its colour pale, and when broken 
up the granular character was evident. 
Urinary Organs. —The kidneys, in appearance, were healthy, 
but their substance was soft; the ureters and bladder normal. 
Thoracic Organs. —When the chest was opened, its contents 
presented a strangely diseased appearance : throughout the whole 
of the lungs I could not detect a single portion of sound substance; 
their structure was destroyed, and, I may add, entirely gangrenous. 
The right lung had formed an adhesion along its whole length a 
little wide of the spinal column: the adhering substance was of a 
yellowish white colour, and resembled a mixture of pus and fibrine. 
This substance was very abundant, and was of the consistence of 
moderate thick jelly. The right lung also contained a large cavity, 
which was about three parts filled with the yeasty-looking matter, 
similar to that discharged from the nostrils: quantities of this sub¬ 
stance were also present in the larger bronchial tubes. The left lung 
was not so far advanced in disease; adhesive matter between it and 
the pleura was present, but the surfaces involved were not so ex¬ 
tensive ; the same kind of sanious matter was also present in con¬ 
siderable abundance. The trachea was in a diseased condition ; 
its mucous membrane along its whole extent, over the larynx, eso¬ 
phagus, nostrils, mouth, &c., was more or less gangrenous. The 
serous membrane covering the costae and the anterior surface of the 
diaphragm was of a dull, dirty green colour, and a very little force 
caused it to slough from the subtextures: it peeled away, in fact, 
like wet paper, and a dark liver-coloured surface was exposed. 
The chest contained about twelve or thirteen quarts of liquid, in 
which floated masses of lymph, portions of lung, &c. 
Circulatory Organs. —The heart was moderately firm in its 
structure, but pale externally; its left ventricle contained a por¬ 
tion of blood not unlike blue ink, which was in a semi-coagulated 
state: the lining membrane of the ventricle had the same blue or 
rather blue greenish tint; the valves to all appearance were healthy. 
The heart, freed from other textures, weighed exactly seven pounds 
four ounces avoirdupois. 
Arteries. —The large arteries, such as the aorta, throughout 
its entire length, to where it divides into the iliacs, appeared 
normal, with the exception of being softer than natural: the colour 
internally was shadowy ; but I could not say such colour resulted 
from disease in the serous membrane itself. 
Veins. —I carefully examined all the large veins, such as the
