LARKSPUR POISONING OF LIVE STOCK. 33 



6.50 p. m. she was found down again and unable to rise. She was 

 moaning as if in pain. At 7.20 her pulse was 65, and at 10.45 it was 

 60 and somewhat stronger. She remained down during the night 

 unable to rise, but at 6.45 a. m., on the following morning, she got 

 upon her feet, moved about and although she fell, was able to rise 

 again. A little later, however, she stumbled and fell and could not 

 rise, but at 8.15 a. m. she was again upon her feet and eating as 

 though hungry. At 10.15 a. m. she appeared quite well, with the ex- 

 ception of some weakness, and was turned back into the pasture with 

 the other animals. 



During the first of this series of illnesses she was given a drench 

 of potassium permanganate, the treatment being repeated in the 

 evening. There seemed to be no reason, however, to think that this 

 had any definite effect. She was also given hypodermicall}^ an in- 

 jection of 25 grains of caffein sodio-benzoate at 10.45 in the evening. 

 There was no evidence that this produced any effect. This case was 

 particularly interesting because of the successive illnesses produced 

 by renewed feeding of the DelpMniuon harbeyi. 



Case 603. 



Case 603 was a yearling heifer, weighing about 550 pounds, which 

 was loaned to the station for experimental purposes by Mr. O. E. 

 Wiseman. From August 2 to August 4 she received 34 pounds of 

 Delphinium, harbeyi^ including stems, leaves, flowers, and buds. This 

 was mixed with hay and corn chop in order that it might be eaten 

 with greater readiness. No effects were noticed until the afternoon 

 of August 4. She was apparentlj^ well at 4.30. At 6.50 she was 

 found lying flat on her side and at first was supposed to be dead. 

 She was breathing, however, and soon kicked a little. A dose of 1 

 grain of atropin was administered subcutaneously. She was raised 

 up so that she lay upon her belly with her head off the ground. In 

 this position she held her head around by her side as if in pain. At 

 6.55 respiration was 24 and the pulse between 75 and 80 and weak. 

 At this time she was given a drench of potassium permanganate. At 

 7.03 respiration was 23 and temperature 101.2° F. At 7.15 a hypo- 

 dermic injection of 30 grains of caffein sodio-benzoate was given. 

 At 7.30 the temperature was 101.3° F. At 7.45 she attempted to get 

 upon her feet but was unable. At 8.20 respiration was 22, ]3ulse 

 about 90 and not very strong. At 9.10 she was upon her feet and 

 from this time showed no further symptoms of poisoning. 



She was brought into the corrals for further feeding on August 18. 

 Between August 19 and August 22 she ate 95.75 pounds of Del- 

 phinium' harbeyi^ the material including stems and leaves. At 4.35 

 'on August 22 she was found lying with her head turned to the right 

 of the body. She got up, staggered about and fell, but lay with head
