inner surface of tlie bowel would be inflamed for several inches 
in extent. In the large intestines the mischief was still more 
apparent, the caecum often contained a multitude of inflamed and 
elevated spots, or in their place ulcerations as large as the im¬ 
pressions made by the ends of one’s fingers on a dusty table, and 
as close as the fingers held together could make them. The colon 
usually presented ulcerations similar to those of the caecum; its 
contents were small masses of hardened foeces dark colored or 
blood-stained; and not unfrequently dark fluid blood in consid¬ 
erable quantity. Sometimes portions of the colon were almost 
gangrenous. In a few cases the intestine had been perforated by 
ulceration, and peritonitis had resulted. The mesenteric glands 
were almost always enlarged; the kidneys were congested, the 
bladder contained healthy-looking urine, or it was tinged with 
bile or blood. 
The lungs were always congested and often inflamed, or im¬ 
pervious to air from serous infiltrations; the air passages were 
filled with frothy mucous, the trachea and larynx were sometimes 
found in a state bordering upon gangrene. In a few instances, 
where the cough had been an unusually marked symptom, the 
smaller air-passages were crowded with nematoid, or thread-like 
worms, the Strongylusparadoxus ; these cases were so few, that 
the presence of the lung-worms can only be regarded as an acci¬ 
dental compl ication. 
Effusion within the pleura, or pericardium, was sometimes 
seen; the blood in the heart cavities was clotted, but the clots 
were soft and in general the blood elsewhere was fluid. On ex¬ 
amination of the blood with the microscope, the blood globules 
appeared shrunken and their margins irregular. In the blood 
drawn from some animals that were killed, bacteria were seen 
with a power of from eighty to one hundred diameters. The 
Bacillus anthracis , which is said to be pathognomonic of anthrax 
fever, was looked for but not found. The brain and spinal 
marrow were repeatedly examined, but without disclosing any 
marked lesion.
