and three year old steers, witli a few yearlings and cows. The 
greater part of the herd were fed hay and herded on cornstalks, 
receiving very good shelter in a thick grove along the bank of a 
creek, from which they drank. Milch cows and yearlings were 
kept on the opposite side of the creek and fed grain and hay reg¬ 
ularly, with plenty of well water. The disease appeared in both 
parts of the herd. 
Symptoms and Pathology .—The animal ceases feeding and 
ruminating, or partially so. In most cases they become excited 
and wild, eyes protruding and glaring, chasing pigs, chickens, 
other cattle; also men. The freaks of their frenzy are quite va¬ 
rious—twitching the tail and ears as if bothered by flies, fight¬ 
ing, bellowing as if lost, frothing at the mouth, many lame in left 
hind leg, some weak in both hind legs, licking the legs, flatus 
passing the anus, though none were tympanitic; urine clear, in 
some cases seemed copious; faeces sometimes tinged with blood 
and usually of a dark brown color, otherwise generally of a nor¬ 
mal consistency. This peculiar color is the first symptom noticed 
in some cases, in the morning when the herd is started up. 
During the day the animal isolates, is stupid and feeds but little. 
One treed a man, kept him there over an hour, and would bellow 
at him if he attempted to come down. One caught a chicken, 
hooked, tore and ate a part of it, which was afterward found in 
the rumen. One gored a tub in which water was placed for him; 
afterwards, he jumped out of the yard, ran to the herd, furiously 
fought some of them; when again separated a club was throw at 
him, upon which he pounced, horning and chewing it. A 
small number were not delirious, and presented but few abnormal 
symptoms. Dulse and temperature I could not obtain with satis¬ 
faction. The different stomachs and contents generally appeared 
normal. The omasum was sometimes impacted, dry and the mu¬ 
cous leaves easily torn. Portions of the intestines were con¬ 
gested and the mucous surface of a deep red color; liver some¬ 
what softened; kidneys sometimes congested and darkened; 
portions of the spleen enlarged and the pulp softened, dark and 
disintegrated. The lungs were normal, though sometimes slight¬ 
ly mottled in the lower portions. In one case I found the mus¬ 
cular portion of the diaphragm very much hypertrophied; also a
