blood cirea, two thirds of a pint, withdrawn from the jugular vein, re¬ 
sembled more arterial than venous blood, coagulated within ten min¬ 
utes, separating a reddish yellow tinged serum. It is understood that 
the complexity of the symptoms are not at all times alike, they being 
dependent upon the progress of the case. The most important diag¬ 
nostic symptom is the character of the urine, but since we are unable 
at all times to be present personally, the history of the case as given 
by the attendant (however unreliable at times), must suffice, and is in¬ 
dispensable unless previous cases appeared in like manner, which, of 
course, must be traced in the same way. 
Autopsy. —In one case I observed a post mortem rigidity which I 
did not notice in others. Tympanitis as well as emphysema I observed 
only in such cases as have been dead for several hours ; whilst in those 
having just expired collapse of the abdominal cavity was found. The 
blood vessels of the subcutaneous tissues very seldom engorged. In 
some cases the muscles were pale, and in others bluish tinted. The 
adipose tissues usually presented a healthy aspect, though in some cases 
icteric. The abdominal cavity usually contained from one half to one 
pint of serum. Peripheric appearance of the stomach often deviated 
from the healthy state; its surface in relation to the liver and spleen 
partook from the former a yellowish color, and from the latter a san- 
guinous hue. 
The contents of the rumen was nearly always voluminous; the reti¬ 
culum partly or totally empty ; the omasson filled with the usual quanti¬ 
ty of dry food, in few exceptions, however, empty ; and the abomasson 
contained mostly an offensive, mushy mass. The contents of the ileum, 
caecum and colon in nearly all cases was of a like offensive character; 
often met with dry, bloody feces in the rectum, unless death occurred 
during purgation. The external presentation of the alimentary canal 
seldom bore any evidence which would indicate the condition of its 
inner aspect; the discoloration of one or the other organs, permeated 
with a yellowish tinge, are the most frequent superficial appearances. 
The epithelial lining of those destroyed presented an inflammatory 
character, whilst in those that died it was partially detached, of a greyish 
hue, the denuded muscular coat congested; the mucous lining of the 
small intestines relaxed, coated with bloody mucus, and distended by 
the presence of gas. The peyers patches were more voluminous and 
livid. The internal coat of the large intestines, and a portion of the 
ileum presented circumscribed greyish green or yellowish surfaces, with 
gangrenic odors, the destroyed were void of the latter change. The
