Q. A. JOHNSON. 
deaths taking place after the cattle had run in the stalk fields 
six days or longer. 
The first symptom that the majority showed was a drow¬ 
siness, that soon passed into coma and then lethargy, with 
paralysis of the sensory nerves and stertorous breathing. One 
man reported that his cattle became rabid in action and 
would pursue any moving object, especially man, but this 
stage soon passed into that of coma, and death soon came to 
the relief of the suffering animal. 
As typical of what was usually found on post-mortem, I 
will give the results of one that I held. The cow was de¬ 
stroyed after having lain about six hours, being then in the 
last stage of death. 
Blood dark, with slight tendency to clot; had very much 
the appearance of strong, unsettled coffee ; microscopical ex¬ 
amination showed a shriveled condition of the red corpuscles, 
much as though the blood had been subjected to the action 
of acetic acid. 
Heart: valvular structure of left side inflamed, those of the 
right side very slightly. 
Lungs: right slightly congested, left filled with dark 
colored blood; was unable to tell whether it was due to the 
disease or from stagnation, the animal having lain on this side. 
Spleen enlarged, of a dark color and showed more or less 
congestion, and of a broken down appearance. 
Liver: anterior lobe much enlarged, posterior slightly. 
Interior face along the blood vessels covered with a thick 
(from one-half to one and one-half inch), straw colored or¬ 
ganized exudate, interior superior border much inflamed, with 
the capsule broken and the tissue of a broken down appear¬ 
ance. 
Gall bladder well filled with straw colored bile. 
Kidneys : left normal, right corticle portion inflamed. 
Rumen well filled with moist aliment. 
Omasum filled with dry material; walls of the folds 
showed much inflammation ; mucous membrane separating 
from the walls and coming away with the aliment, but there 
was no engorgement.
