The plan of feeding, as with Sheep 421, was to have the animal eat 
as much of the H. Jioopesii as it would take. The plant was cut up 
and mixed with a certain amount of alfalfa hay, as the animal would 
not eat it without hay. The quantity of hay mixed with the H. 
Jioopesii varied, being sometimes as much as one-half of the quantity 
of the poisonous plant. This feeding was continued from May 30, 
and the animal appeared in good condition with no evident symp- 
toms of poisoning until June 23. On June 18 it was turned into the

was confined to the corrals. 
On June 23 it was noticed that while lying down the sheep regur- 
gitated, and there was some belching of stomach gas. On June 24 
some green material was noticed about the mouth, and on June 25 
it was found that she had vomited. On June 27 the animal had 
become quite weak and was not inclined to stand. At this time she 
evidently, to some extent, had lost her appetite for any kind of food. 
The feeding, however, was continued. On June 29 the pulse was 
noted as somewhat irregular and the animal was lying down most 
of the time, although still strong enough to stand. From this time
