ENSILAGE POISONING.

the year, he had lost four cows with what appeared to him to 
be exactly the same disease. All of the animals taken sick the 
year previous to the time of my visit died. 
The first symptoms noticed were a loss of appetite, the eyes 
appeared bright, there was no lopping of the ears, the respira¬ 
tions were labored, the temperature normal, there was no t>ain, 
and no thirst, although the animals lapped the water very fre¬ 
quently ; the cow seemed weak. There was a slight elevation 
of temperature, about 103, in the early stages, but later after 
the first 24 hours the temperature dropped below normal, rang¬

even breaking the boards with the force of the exertion. The 
animals gradually grew weaker until death took place, or they 
were destroyed when there were no hopes of recovery. The 
symptoms and progress of the disease were practically the same, 
and the owner assures me that the four cows lost the previous 
year died with the same symptoms. 
Autopsies made on all three animals, gave the following 
results : 
The animals were well fed and in good flesh for dairy cows, 
the intestines were irritated, and severely congested in patches, 
the stomachs were also congested in patches, the manifolds con¬ 
gested and the food contained in the manifolds being abnormally 
hard and dry ; the omenta were hard and stiff, and looked as if
