Q - . W. BUTLER. 
the mucous membrane, where the worms were found, were 
much larger, being about the size of a pea and red in color. 
A great many small worms were found free in a portion of 
the large colon, similar to case 2. The liver presented a num¬ 
ber of light colored spots and its parenchyma was soft, being 
easily broken down; numerous ecchymosed spots were 
scattered along the intestinal tract. There were a number of 
black spots on peritoneal coat of small intestines which resem¬ 
bled ink stains and the mucous membrane immediately be¬ 
neath these spots presented pit-like depressions, but there 
were no ulcers. The lymphatic glands along colon that con¬ 
tained parasites were enlarged, lungs were congested, mucous 
membrane of larynx, pharynx and trachea inflamed and brain 
congested. 
Remarks .—In case 1 the symptoms were such as to impress 
one with the expectation of finding some brain lesion, but, as 
stated above, the post mortem revealed nothing unnatural in 
that organ. I cannot account for the symptoms of brain af¬ 
fection, as I think it scarcely probable that they were due to 
the irritation set up in the intestines by worms, and I think it 
equally improbable that an abnormality of the brain, such as a 
tumor or blood extravasation, would escape my notice in mak¬ 
ing a pretty careful examination. Judging from the amount 
of intestinal inflammation in case 1, I would think there must 
have been symptoms of abdominal pain exhibited in the early 
stage of the attack; and this may have been the case in the 
night, when the animal was not under observation. 
Cases 2 and 3 certainly presented symptoms of rabies, and 
my suspicion of the presence of that disease was at once 
aroused when I was first called to see case 2; yet a searching 
inquiry as to the manner in which the animal might have re¬ 
ceived the virus, elicited nothing to make the matter clear. 
No one knew of there having been a rabid dog in the neigh¬ 
borhood. This animal had during his illness a small sore on 
the upper lip, but how he came by it or what caused it no one 
knew. As I was the first to notice it and as the horse had 
been sick some time before I saw him, I thought it quite pro¬ 
bable at the time that it was caused by striking the head
