Case 605. 



Case 605 was a yearling heifer loaned for experimental purposes 

 by Mr. J. H. Eilebrecht= She was estimated to weigh about 450 

 pounds. 



During July 30 and 31 she received 35 pounds of Delphiniu^m har- 

 heyi, the material including stems, leaves, and some flowers and 

 seeds. This material was chopped up and mixed with chopped hay 

 in order that the animal might eat it more readily. She was fed at 5 

 p. m. on July 31 and was apparently entirely normal. At 5.30 it was 

 noticed that she appeared somewhat weak upon her hind legs when 

 forced to walk about the corral. She soon fell, her fore legs giving 

 away first, and she was unable to get up. She moaned as though 

 in pain. Several times she tried to get up but apparently did not 

 have sufficient strength. Her pulse at this time was 60, her tempera- 

 ture 102.2° F. There was no evidence of bloating. At 6 p. m. 

 respiration was TO and rather irregular. The pulse was slower than 

 when observed before. At 6.11 she suddenly got upon her feet 

 and walked away. She was weak and staggered but otherwise 

 seemed all right. No further symptoms were noticed during that 

 evening. 



It was noticed that during this illness she urinated rather freely. 

 She appeared well on the morning of August 1 and the feeding 

 was resumed, giving her as before stems and leaves of Delphinium

 fed with hay. During the forenoon she ate 12 pounds of this 

 material. At 1.15 p. m. while walking about in the corral she 

 suddenly fell and was unable to rise. The pulse was 68, respira- 

 tion 68 and somewhat irregular. She was constipated and moaned 

 as though in pain. At 1.25 her temperature was 102.3. At 1.30 

 she suddenly got upon her feet, ran around the corral, and fell 

 down again. At 1.45 her pulse was 60 and respiration 45. At 1.50 

 she got ujion her feet. She stumbled as she attempted to rise, but 

 did not go down again. "^^Tien started up she stumbled and fell 

 upon her knees, but was able again to get upon her feet. As she 

 stood, the abdominal muscles contracted as if she were in great 

 pain and there was also spasmodic twitching of the muscles of the

She remained on her feet after this time and as she appeared 

 normal the feeding was resumed at 3 p. m. She ate 9| pounds. At
