leaves of two plants (possibly 3 or 4?) and soaked them over 

 night in abcut a pint of milk, of which he gave about a gill at 

 about 9 A. M. to his tom-cat. The cat took about one-half of it. 

 "About 9:30 it seemed to take effect and he tried very hard 

 to vomit but could not. He took long, deep breaths. He was 

 quiet and wanted to sleep very hard. All of a sudden he would 

 tremble very hard, then again very little. A watery fluid 

 pasccd from his eyes and mouth. He chose a spot in the sun 

 and when driven away walked back in a staggering manner. He 

 had no appetite. His senses seemed to be duller, as he did not 

 care for anything. He went to sleep about 10:30 but did not 

 sleep sound. He seemed to be in an unconscious state for the 

 rest of the day. The next morning about 10:30 he walked about 

 three rods and there died about noon." 



Oscar lives in the country and I did not see the cat until he 

 brought it to me dead. Weight estimated 4)4 pounds. Post- 

 mortem examination by Dr. H. C. Schoepfle and myself showed 

 no lesion, inflammation, congestion or unnatural appearance of 

 any organ. Brain not examined. Death followed more quickly 

 in this case than in any of our other experiments. The cat was 

 not fed the evening before giving the poisoned milk, so that 

 digestion was probably rapid. As it was not taken from home 

 and so was not kept in confinement, the case is especially 

 interesting. 



No. 2. A female kitten weighing after death thirty ounces, 

 had probably never been handled by anyone until caught for 

 this experiment. My pupil, Alton Fuchs, cut up about half a 

 pound of snake-root I had gathered and boiled it about an hour 

 in a quart of water. When the water had become reduced to a 

 syrupy liquid, about one tablespoonful in volume, it was poured 

 into the throat of the cat and the outside of the throat tickled 

 so that it was all swallowed. "Soon after the decoction was 

 administered the cat acted as if she wanted to vomit but did not 

 vomit at any time. When first turned loose in room of barn it 

 was very active, but after half an hour seemed rather stupid. 

 x\fter an hour she escaped, but was caught while trying to get 

 through a fence, being less active than before poisoning." I first 

 saw her aVjout 2)- 2 hours after extract was given, lying in natural 

 position, eyes directed toward us, but rather dull, took notice of 

 anything held near but indisposed to move. Respirations 38 and 

 30 per minute, doubtless increased by our presence. Movement 

 of the back seemed greater than in normal breathing, and 

 occasionally a spasmodic contraction ran along the muscles of 

 the back. About noon the next day she took some milk. The 

 symptoms continued much the same as the previous day, the 

 spasms more frequent and pronounced, becoming worse in the
