50 BULLETIN 365^ U. S. DEPAETMENT OF AGEICULTTJEE. 



day she ate about 7^ pounds of DelphiniuTTh 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 Tnenziesii, 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 Avas 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.
