STAGGER GRASS AS A POISONOUS PLANT. 7 



On April 18, at 11.30 a. m., experimental feeding was commenced 

 again with the same animal. On that date she ate 40 grams of 

 ground roots without any distinct symptoms of illness, and on April 

 19 she ate 10 grams. Between 12 and 2 p. m. on April 19 it was 

 evident that she felt very uncomfortable. There was some constipa- 

 tion, although there was none on the preceding day. She was nau- 

 seated, but did not vomit, and would eat nothing. After 1 o'clock 

 there was slight salivation. 



On the succeeding da} r , April 20, she had entirely recovered, was 

 eating grass, and the constipation had been relieved.

On May 4 feeding was commenced again, after 24 hours without 

 feed. She ate 38 grams of leaves, the feeding commencing at 11.15 

 a. m. Between 3 and 4 p. m. there was distinct evidence of discom- 

 fort, and she ceased to eat, but there were no further symptoms of 

 poisoning. The feeding was continued on May 5, when she ate 87 

 grams of the leaves. No symptoms appeared on that day, but on 

 May 6, at 11 a. m., she was found to be breathing as if in discom- 

 fort and staggered when upon her feet. At 12 o'clock she groaned 

 as if in pain, was constipated, and stopped eating entirely. There 

 was some salivation. At 1.19 p. m. she was given 5 grains of caffeine 

 sodiobenzoate. At 2 o'clock she appeared to be in good condition.
