day she ate about 7J pounds of Delphinium menziesii. At 4 p. m. 
she appeared uneasy. There was occasional forcible expiration and 
much constipation. After a time her uneasiness seemed to subside 
and she began to ruminate and appeared hungry. At 5 p. m. she 
was run around the corral, with no- result. Feeding was renewed 
at 5.15 p. m., and during the evening she received 18.75 pounds of 
Delphinium menziesii, including the seeds. At 9.30 p. m. she was 
found with her back arched, but appeared fairly well. At 10.15 
p. m. she stood with her tail between her legs and her head rather 
low. The impression was that the poison was taking effect. She 
started to run about the corral, stumbled and partly fell, but recov- 
ered herself, then fell and could not rise. The observer went to the 
laboratory to get a remedy and on returning found her upon her 
feet, and she remained upon her feet even after running around the 
corral. She was left again at about 11.40. During all the time she 
was watched she was uneasy. She occasionally would expel gas 
rather violently, and once she moaned. She was evidently very un- 
comfortable, but not very sick. At 12.10 midnight she was on her 
feet, but moved around the corral slowly. She began to back un- 
easily with her head low, and fell and, although making violent 
efforts to rise, was unable to do so. At 12.15 she was given subcu- 
taneously physostigmin salicylate, 1 grain; pilocarpin hydro- 
chlorid, 2 grains; and strychnin sulphate, 1 grain. She was in great 
pain, breathed noisily, and occasionally expelled gas from her 
stomach. She would stretch her legs out rigidly and kick violently, 
moaning all the time. At 12.40 she passed a little hard feces. At 
12.45 her respiration was 40 and continued at about that rate. She 
perspired copiously and acted like an animal in a violent attack of 
colic. At 1.25 she raised her head, making efforts to rise, but fell 
back, striking her head violently upon the ground. This was re- 
peated at 1.30. From this time she seemed to be somewhat easier, 
although the change was rather gradual. She lay upon her side, 
breathing noisily. Her legs much of the time were stiff, but the 
movements were not so convulsive and apparently- her pain was less. 
During the most violent spasms of pain she was given a little am- 
monia inhaled from saturated cotton. At about 2 a. m. after several 
violent efforts she succeeded in getting upon her feet, staggered across 
the corral, but did not fall. She was watched at intervals during 
the rest of the night and was upon her feet all the time. She was 
given a little hay and corn meal in the morning and hay at noon. 
On the following day she appeared to be entirely recovered. 
EXPERIMENTAL FEEDING OF DELPHINIUM ROBUSTUM TO CATTLE. 
The species of larkspur which has been identified as Delphinium 
robustum and which is quite different from Delphinium barbeyi and 
Delphinium menziesii of the Mount Carbon station is abundant in
