CONTRIBUTIONS TO THE PATHOLOGY AND 
was almost, I may say, wedged with masses of fecal matter in a 
somewhat dry state. This fecal matter consisted, in a great measure, 
of hay and straw, very little changed by the action of the stomach 
and bowels upon it. I picked out several pieces of hay and straw 
at least two inches each in length ; in fact, the masses were prin¬ 
cipally composed of such. The tissues of this bowel were exten¬ 
sively inflamed, but the inflammation itself did not appear to have 
been of a very severe or very acute kind : a small portion of 
lymph was effused, which was of a dirty pale-brown colour. The 
rectum was completely empty, and apparently free from inflam¬ 
mation ; the tenacity of the tissues of all the bowels was feeble: 
I tore them up with very little force ; the mesentery and omentum 
were free from disease. The liver was of the colour of clay, and 
its substance easily broken up. 
Urinary Organs. —The bladder contained about a pint of urine; 
its mucous membrane was very pale ; the ureters were healthy; 
the kidneys also, and moderately firm. 
Organs of Circulation. —The heart, its valves, &c. were healthy, 
but pale; its right ventricle contained a dark clot of blood, not 
very firm, but free from fibrinous clots : a small clot was also in 
the left auricle, of a similar character. The large arteries and 
veins were normal. The weight of the heart, when free from the 
aorta, &c. was eight pounds six ounces and a half, avoirdupois. 
Respiratory Organs. —The nasal passages, the larynx, trachea, 
bronchial tubes, &c. were perfectly normal; and the lungs cre- 
pitous throughout. The right lung was a little congested; the 
left lung slightly so in its most inferior parts; the pleura was per¬ 
fectly healthy. 
Brain , $c. —The brain was moderately firm, and its membranes 
free from blood, or nearly so : the medulla spinalis was very 
similar in every respect. I also examined some of the large nerves, 
but failed to detect anv anormal state in their tissue. 
Muscles of Animal Life. —The muscles of this class were 
normal; the colour of them was good, and their structure mode¬ 
rate^ firm. 
Case II. 
June 18, 1843.—Was requested by Mr. J. B. to examine a 
mare. 
History, 8$c .—The animal is a mare of a bright bay colour, nearly 
three parts bred, stands sixteen hands one inch high, is six years old, 
was bred by a farmer who resides in the neighbourhood. Three years 
ago the mare in question had a severe attack of pneumonia, for which 
she was bled, and also blistered on both sides of the chest, besides
