during this time 106 pounds of E. urticaefolium, 138 pounds of grass, 
and 11.5 pounds of bran, an average daily ration of 10.6 pounds of 
Eupatorium, 12.5 pounds of grass, and 1 pound of bran. The material 
was kept before her constantly in the attempt to make her eat as much 
as possible. She did not take kindly to the E. urticaefolium , and it was 
necessary to keep mixing fresh grass with it. A calf (No. 700) was 
allowed to take all her milk. 
On September 30 it was evident that she was losing in activity and 
that her flow of milk was much reduced. She moved slowly and after 
a little exercise trembled noticeably in the shoulders, hips, and thighs. 
On October 1 she was much constipated and strained when defecating. 
She ate no E. urticaefolium and even refused to pick grass out of the 
mixture. On October 2 she was lying down and unable to get on her 
feet. Grass was offered to her, and she tried to eat it. The nose and 
lower jaw trembled violently. After attempting to rise, she went over 
on her side, with marked trembling about her head. Her flow of milk 
had nearly stopped. On October 8, in the morning, she was found dead. 
Her temperature during the experiment was rather low, but hardly 
subnormal. At the autopsy the liver was somewhat yellowish, the 
duodenum was slightly congested, and the ileum showed many patches 
of congestion. Nothing else abnormal was noticed. 
Calf 700.—This was a male calf which on September 21 was only 2 or 
3 days old. He was put with cow 699 and took all her milk supply. 
He showed no ill effects from the milk, but suffered from lack of nourish¬ 
ment as the cow began to dry up. 
From October 4 to 9 he was fed with E. urticaefolium by the balling 
gun, receiving a total of 5.6 pounds. This would be equivalent to 56 
pounds for a 1,000-pound animal, or an average daily ration of 9.3 
pounds for six days. During this time he was fed on skimmed milk. 
He showed nausea on October 8, and on the 9th this was accompanied 
by vomiting, with loss of appetite. On October 7 and 8 he shivered at 
times, but this may have been due to insufficient food rather than to 
any toxic effect of the E. urticaefolium . He was killed and autopsied 
on October 10. The result of the autopsy was entirely negative. 
ShkFp 367.—This sheep, a yearling ewe weighing 60 pounds, was fed 
at Fancher, Ill., from September 22 to 28, inclusive, on fresh plants of 
E . urticaefolium . She ate 1.1 pounds on September 22, and on the re¬ 
maining days, except September 24, she was given the material by a 
balling gun, receiving all told 4.3 pounds, or on the basis of 7.1 pounds 
per 100 pounds of animal, an average daily ration of 1 pound. 
In the afternoon of September 25, after having received the plant at 
the rate of 3.8 pounds per 100 pounds animal weight, the sheep appeared 
inactive, preferring to lie down. On September 26 it was thought that 
she trembled some after being exercised, and there was some trembling 
of the jaw when she was being fed with the balling gun. On September
