CONTRIBUTIONS TO THE PATHOLOGY AND 
5. The membrane of the mouth is hot, and the tongue is soapy. 
6. The surface of the animal’s body presents here and there 
patches of perspiration. 
7. Occasionally she raises her head, brings her nose close to her 
left side, looks at the side anxiously ; then slowly takes away her 
head, and lets it fall heavily upon the straw. 
8. The hind limbs are considerably swollen, particularly around 
the hock joints ; the swollen parts are hard, hot, and somewhat 
tender when pressed upon. 
9. She struggles violently, and attempts to rise occasionally; 
but the hind limbs are powerless. 
Treatment , tyc. — I had recourse to the common colic draught ; 
had the spine and back well fomented with hot water, and after- 
wards rubbed with a strong stimulating liniment : she was then 
well covered with rugs, and for a long time afterwards she lay 
perfectly at ease. About twelve o’clock she was in such a com- 
fortable state, that it was deemed safe to leave her alone, which 
accordingly was done ; but the man having the care of her, upon 
entering the stable about six o’clock the following morning, dis- 
covered that she was dead. The straw was not much disturbed, 
and, from the manner in which she was laid, she appeared to have 
died very quietly. 
Examination : Trunk, fyc. — I did not observe any thing peculiar 
on removing the skin, until I came to the hind limbs, when the 
following conditions presented themselves. Cellular tissue around 
the hock joints filled with bloody deposits : these deposits varied 
in colour; the darkest portions were almost black — the lighter 
portions were of the colour of cinnamon : the cellular tissue around 
the patella joints was in a similar state. 
Respiratory Organs. — The nasal passages, the larynx, the 
trachea, and the bronchial tubes, were all healthy. The left lung 
was congested : the pleura costalis of the right side was perfectly 
healthy : the pleura costalis of the left side along the middle region 
of the chest was strongly injected with a vast number of minute 
red vessels : the injected portion extended the whole length of the 
chest, and varied in depth from three to six inches : along this in- 
jected region, the left lung adhered by a thin coating of serum. 
Organs of Circulation — The large vessels, the arteries, and the 
veins in immediate connexion with the heart, were all healthy. 
The left ventricle of the heart contained a number of purple- 
coloured spots; these spots were the most numerous around the 
muscular pillar within the cavity: both ventricles contained clots 
of fibrin intermixed with tar-like masses of semi-coagulated blood. 
The heart, when divested of all fat and of its large vessels, weighed 
exactly seven pounds avoirdupois.
