CONTRIBUTIONS TO THE PATHOLOGY AND 
green to a dark purplish kind of red ; the tissue could be separated 
from its subtextures, leaving a dull red surface exposed; portions of 
lymph floated in the effused liquor. The pericardium was greatly 
inflamed, particularly over its internal surface; it presented the 
same roughened and congested state the pleura did; the bag con¬ 
tained from a pint to a quart of serum, in which was deposited 
three or four slender strings of lymph : the valves of the heart, 
particularly those of the left ventricle, were considerably roughened 
from inflammation: both ventricles contained clots of firm coagu¬ 
lated fibrin; the weight of the heart was exactly six pounds 
twelve ounces avoirdupois. The lungs themselves were much con¬ 
gested, but crepitous throughout. 
Muscles, Joints, 8$c. —The muscles of animal life were normal in 
every respect. 1 carefully examined the joints, particularly those 
so much tumefied. The cellular tissue immediately under the skin 
contained a quantity of serous fluid*, intermixed with which was 
a deposit of glairy colourless matter of the consistence of thin 
jelly; this deposit existed in the greatest quantity around the lower 
and tendinous portion of the “ extensor metacarpi magnus.” The 
subtextures were also highly congested with small vessels; the 
internal surfaces of the synovial membranes were of a dusky blue 
red colour, and the synovia was turbid. 
Air Passages. —The trachea was filled with frothy spume ; its 
mucous membrane was shadowy, with portions here and there more 
injected than the rest; the same with respect to the nasal passages 
and the bronchial tubes. The mucous membrane covering the 
larynx and pharynx was swollen, and exhibited patches of a livid 
colour : around the edges of the epiglottis was greatly tumefied, in 
which was embedded, as it were, several small ulcers, with very 
ragged borders. The floor of the larynx contained one large ulcer 
of about the size of a shilling ; very little force was necessary to 
slough the membrane from the cartilages and structures in con¬ 
nexion with it. 
Brain, fyc. —The colour of the brain was not good, nor was its 
tissue so firm as it ought to have been; its ventricles contained 
serum, a small quantity of serum was also effused at its base. The 
spinal cord was clearer in colour and firmer in substance. 
Digestive Organs, Bloodvessels, fyc. —The stomach contained 
but a very small portion of food ; the small intestines were pale in 
colour, and contained a brown watery matter; the large intestines 
were nearly empty; the arteries and veins were normal, and their 
structures moderately firm. 
* I speak of all the joints of the left fore and hind legs, below the patella 
and elbow.
