stopped. Gave each cow large doses of mag. sulph., followed 
by tonics. 
On the 17th I for first time saw the cows come out of stable. 
Here was where the trouble showed itself the most, coming 
from dark stable to the light. The first few steps the fetlock 
would hardly bear them, would turn and almost throw them 
down. As soon as they came to the light, they would start 
back, stare around, blink their eyes, were not able to distin¬ 
guish objects. One cow especially could hardly get through 
an opening twelve feet high by fifteen wide, making several 
attempts before getting out. She wonld start out, then step 
back, start again, bend down until belly almost touched the 
ground; after doing this several times she got down upon 
her knees, rested in that position a few seconds, then got up 
and passed out without any trouble and went to eating. She 
did this three mornings in succession before improving. 
The whole herd went through these actions more or less in 
getting out of the stable ; all were very thirsty ; drank a great 
deal of water. Of the two which were in the stable, the one 
that was the weakest but able to stand got down in the night 
and died, while I was looking at the others. She ate some hay 
and drank water early in the morning. The other one still 
down, but eating and milking some. I saw them again in 
the evening ; were apparently much better after standing 
out all day. The stiffness and trembling was improved; 
18th.—Came out of stable much the same as yesterday, 
but did not seem so nervous, and it soon passed off after 
being out. The cow that had been down since the 14th died 
during the night. 
I held a post-mortem on the two which had just died. 
The first thing noticed upon opening them was a peculiar 
smell, different from what 1 had ever experienced in any 
other post-mortem. As near as I can describe it, it was like 
rotten eggs. I found all the internal organs in a normal, 
healthy condition except the stomachs. The mucous mem¬ 
brane was almost entirely separated from the wall of the 
rumen and manyplier, leaving it of a purplish hue, looking 
very much as if it had lain in water for several days. Both
