phor water. At 3.25 the pulse was fairly strong. At 4.25 he very 
nearly succeeded in getting upon his feet. The muscles of the shoul- 
ders and flanks were trembling much of the time. 
As he was much constipated, feces being discharged only once dur- 
ing the day, he was given at 6 p. m. 12 ounces of Epsom salt as a 
drench. At 9.10 p. m. he appeared very much brighter than at any 
time during the day. Trembling was not so pronounced and the pain 
was less. He breathed normally, held his head from the ground 
and took notice of what was passing around him. He was not seen 
again until the morning of August 16. At 6.45 a. m. on August 16 
he got up, ate a little hay and drank water. During the forenoon 
of August 16 he lay down most of the time but occasionally got up 
and walked from place to place. The improvement continued during 
the afternoon and night. He still staggered when walking and re- 
mained upon his feet only a few minutes, but could get up and down 
at will. On the morning of August IT there was still some trembling 
of the surface muscles of the shoulders. Plate XI, figure 6, was 
taken at 7.25 a. m. on August 17 when he appeared fairly normal. 
He was driven back into the pasture still showing weakness, 
trembling, and staggering when hurried, but after this his recovery 
was rapid and complete. 
EXPERIMENTAL FEEDING OF DELPHINIUM BARBEYI TO CATTLE IN 1910. 
The experimental feeding of Delphinium barbeyi in 1909 had 
indicated somewhat clearly the symptoms of poisoning and the 
dosage so that the work of 1910 was largely directed to experiments 
with various remedies. The discussion of these remedies is taken up 
later in this paper. Table II gives a summary of the experimental 
feeding of Delphinium barbeyi to cattle during this second summer. 
Forty-three feeding experiments were conducted on 24 different 
animals. Following is a detailed description of some of the more 
typical cases. 
Case 612. 
Case 612 was a yearling heifer loaned for experimental purposes 
and weighing about 500 pounds. From July 2 to July 5 she received 
76.5 pounds of Delphinium harbeyi, including leaves, stems, and 
flowers. At 4.15 p. m. on July 5, as the animal had apparently felt 
no effect from the feeding, an attempt was made to run her about the 
corral. After being run about a few times she began to tremble, 
her legs giving out, and she fell and was unable to rise. Respiration 
was 60 and irregular and the pulse 160 and weak. At 4.20 she fell 
over upon her side, the surface muscles contracting spasmodically. 
At 4.24 the pulse was 100 and rather weak. At 4.27 she was given
