A few of tke typical cases will be noticed in detail, as follows : 



Case 117. 



Case 117 was fed on flowering tops of DelphiniuTn rrhenziesii from 

 June 7 to June 9, receiving, all told, 79.5 pounds, or about one- 

 eleventh of its weight. At 9.25 p. m. June 9, when disturbed, he 

 attempted to walk and fell- down, recovering himself with little 

 effort. Other than this there were at this time no symptoms of 

 poisoning. He was observed up to 10.30 p. m. and at that time 

 seemed to be fairly well. On the morning of June 10 he was found 

 dead. He lay upon the left side with his head lower than the rest 

 of the body. Some of the contents of the stomach had flowed from 

 the mouth and nostrils. The heart was in diastole, both sides being 

 filled with blood. The pericardial fluid was slightly bloody and 

 abundant. The external walls of the ventricles showed petechise. 

 The lungs were congested. The fluids of the pleural and peritoneal 

 cavities were also slightly bloody. The trachea contained some of 

 the contents of the rumen. The inner wall of the trachea was con- 

 gested and this condition extended into the bronchi. The inner wall 

 of the first stomach was inflamed beneath the mucous membrane, 

 the inflammation being especially deep at the cardiac end of the 

 stomach. The same condition of the wall beneath the mucous mem- 

 brane was found in the second stomach at the cardiac end. The 

 inner wall of the fourth stomach was also inflamed at the cardiac 

 end. The duodenum was not inflamed near the stomach but there 

 were deep spots of inflammation near the entrance of the bile duct. 

 More or less congestion was found throughout the ileum, this being 

 so deep in some spots as to show through from the outside of the 

 intestine. The left kidney was congested. The brain was congested, 

 probably due in part to the fact that the head was lower than the 

 body. The immediate cause of death was asphyxiation, resulting, 

 partly at least, from the introduction of the contents of the stomach 

 into the trachea, although it seems probable that this was accom- 

 panied by respiratory paralysis. 



Case 82. 



Case 82 was an old cow weighing about 1,000 pounds. From 

 June 11 to June 14 she ate 116.5 pounds oi Delphiniurrh menziesii 

 in flower. It was noticed on the morning of June 14 that she was 

 much constipated. She showed no other symptoms of poisoning un- 

 til 3.20 p. m. of that day, when she was found down. She was able, 

 however, to get upon her feet, but went down again immediately. 

 At 3.26 she was given hypodermically physostigmin salicylate, 

 .1^ grains ; pilocarpin hydrochlorid, 3 grains ; and strychnin sul-
