7 pounds. He received, all told, on the basis of 1,000 pounds of animal 
weight, 82.4 pounds of E. urticaefolium , a daily ration of 11.8 pounds, 
during the time he was eating. During this time he was also fed hay in 
quantities not weighed on October 9, 13, 14, and 15. No symptoms of 
poisoning were shown until October 15. On this day the animal was 
depressed and constipated. He lay down much of the time, and some¬ 
times refused to rise. He ate very little of the hay. On the 16th his 
condition was' unchanged. On the 17th he could get up, but would do 
so only with considerable urging. He showed no desire to eat either 
hay or green grass. He was taken out of the pen, and after being led 
around a little, trembled violently and lay down. It was difficult to 
make him get up and return to the pen. On October 18 and 19 he grew 
gradually weaker. He could get upon his feet, but trembled violently 
when standing. The respiration was rapid. He ate nothing except 
a few handfuls of grass and a very little grain. 
He died on the morning of October 20 without any struggle. Death 
occurred on the sixth day after the last feeding of E. urticaefolium . 
Observations upon the temperature during the illness showed nothing 
abnormal. 
In the autopsy, petechise and hemorrhagic spots were found on the 
heart, both on the auricles and ventricles and also on the aorta and 
vena cava . The walls of the duodenum, jejunum, and ileum were con¬ 
gested, and there were homorrhagic spots on the cecum. The liver 
was light in color, possibly somewhat degenerated. There was nothing 
else abnormal. 
Bull 663.—This animal, a bull, was brought in for feeding October 7, 
1914, He had been in pasture on the Arlington farm since the preceding 
March and was in good condition, weighing 692 pounds. 
The plants used for this animal had been shipped in from Beecher City, 
and autoclaved at a pressure of 7 pounds in order to destroy any possible 
germs of disease. This sterilized material was fed as follows: October 
8, 5.2 pounds; October 10, 10.5 pounds; October 12, 26 pounds; October 
14, 29 pounds; October 15, 15 pounds; making a total in 8 days of 85.7 
pounds. On the basis of 1,000 pounds of animal weight, this would 
have been 123.8 pounds of E. urticaefolium , an average daily ration of 
15.45 pounds per 1,000 pounds of animal weight. Hay was given on Octo¬ 
ber 13 and 15 and on the days following. No symptoms were noted until 
October 15; then the animal exhibited constipation and a loss of appetite. 
On the 17th when he was led about, the exercise caused more or less 
labored breathing and there was some trembling of the muscles of the 
flanks, hips, and muzzle. On the 19th he was somewhat worse; he had 
little appetite, showed a disinclination to stand, and exhibited the same 
muscular trembling as on the 17th. On October 20, while still disin¬ 
clined to stand, he, on the whole, showed improvement, and after this
