27 she was constipated; no further evidence of trembling. On Septem¬ 
ber 28 she trembled after exercise in the morning, and the lower jaw 
trembled when she was being fed with the balling gun. She grew weaker 
during the day, lay down most of the time, ate very little, and trembled 
when on her feet. From September 29 to October 1 her condition con¬ 
tinued much the same as on September 28, with gradually increasing 
weakness until on October 1 she was unable to rise or even to remain 
in an upright position, and lay on her side during the day. Plate 54 
shows the condition of the animal. The urine and feces were bloody. 
She was found dead on the morning of October 2. There had been 
almost a complete loss of appetite, so that she had eaten very little 
during the experiment and weighed after death only 43 pounds. 
The records of temperature, pulse, and respiration showed nothing 
unusual except a rather high pulse rate. The autopsy showed nothing 
distinctly abnormal, except that the liver had a spotted appearance and 
was possibly somewhat degenerated. 
Sheep 368.—This was a ewe about 4 years old, weighing 100 pounds. 
She was fed at Fancher, Ill., from September 22 to 24, 1915, with the 
balling gun, receiving a total of 5 pounds, an average daily ration of 1.7 
pounds. She became nauseated during the feeding on September 23, 
but showed no further symptoms at that time. While being fed in the 
morning of the 24th some trembling of the nose was noted and the animal 
preferred to lie down. A little later the trembling and weakness became 
more marked, increasing until she was unable to stand and went over 
upon her side, salivating and vomiting. Plate 55 shows her condition 
at this time. She died at 1.30 p. m., having lost 12 pounds during the 
experiment. Her temperature remained normal during the experiment. 
In the autopsy the only marked change was in the liver, which presented 
a mottled appearance. 
Sheep 369.—This animal was a yearling ewe weighing 63 pounds. She 
was given E. urticaefolium with the balling gun, at Fancher, Ill., from 
October 3 to 7, 1915. She received 0.22 pound on October 3, and on the 
following days received four feedings of 0.22 pound each, thus getting 
all told 3.7 pounds. On the basis of an animal of 100 pounds this would 
be 5.9 pounds, or an average daily ration of 1.2 pounds. 
While she was being fed in the afternoon of October 5, after about 1.5 
pounds of the plant had been eaten, there was some trembling of the 
head. At the end of the first feeding on October 6 there was trembling 
of the jaw; at this time about 2.2 pounds had been eaten. There were 
no other symptoms until the morning of the 8th. When first seen on 
that day, she was lying down, and when made to rise walked a little way 
and lay down. The respiratory movements were deep and jerky, and 
she lay with the eyes half closed, grunting with each expiration. A little 
later when made to rise she stood humped up and moved about uneasily. 
The forelegs began to tremble, the trembling increasing in violence for
