they had been taken out and dried ; the liver was congested, the 
bile being thick and dark, and in abnormally large quantities; 
the spleen contained some haemorrhagic spots ; the kidneys and 
bladder were normal, as was the urine. The lungs did not col¬ 
lapse on opening thoracic cavity, and were found to be greatly 
distended with air, or gas (there was no odor to this), which had 
infiltrated into the cellular tissue to such an extent that the 
lungs completely filled the thoracic cavity ; this accounted for 
the labored respiration, which had proved extremely puzzling. 
The mucous membrane of trachea and bronchial tubes was 
slightly congested, and the tubes were filled with large amounts 
of mucus; there were no parasites observed, either in the lungs, 
or other portions of the body. 
The cerebral meninges were congested, as were the brains of 
all animals ; this may have been due to the weak heart’s action. 
From all three animals cultures were made on agar and gelatine, 
from the liver, heart, blood and lymphatic glands. Smear 
mounts were also made for examination. No pathogenic bac¬ 
teria were found in any of the cultures. 
The treatment adopted was a purgative followed by stimu¬

ings to determine the cause, if possible, was made. 
Two of the cows stood side by side, the other was some 30 
feet away. 
There were 28 cows in the stable, confined in stanchions in 
two rows facing, with passage ten feet wide between them. 
These three cows happened to be in one row, but the year previous 
two cows had died from one row, and two from the other. The 
stable was well lighted, well ventilated, and dry, there being a 
basement below. Spring water was piped into the barn ; the 
same water was used at the house, and seemed to be of excel¬ 
lent quality. 
The ration consists of gluten meal, bran, and a small amount 
of corn meal, a good quality of timothy hay and clover was 
fed, together with ensilage. The ensilage was taken from a
