energy, so I thought she might revive. At the last were a few 

 kicks. Half an hour after she had expired an auricle was still 

 beating. The stomach, caecum and colon were filled with 

 partly digested snake-root. Bladder filled, although she had 

 drunk no water or milk for several days. Viscera appeared 

 natural. We were not sure whether the veins were a little 

 engorged. There had been no constipation of any consequence. 

 Total amount of snake-root consumed was between two and 

 three ounces. Death occurred 120 hours after first feeding of 

 snake-root. 



No. 9. Female rabbit weight 83 ounces, taken from her 

 home, Dec. 23. Temperature in next three davs taken onlv five 

 times, ranged from 99.8° to 101.9°. At 3:30 P. M., Dec. '26, I 

 gave her in milk about 3-4 ounce of extract from same bottle as 

 that used for the injection of No. 8. It had already been twice 

 boiled for a long time. I gave her some of this with milk or 

 cabbage or lettuce on each of the three succeeding days, about 

 one ounce altogether. Dec. 27, 7:30 A. M., temperature 102.2°; 

 11:35 A. M., temp., 103.5°; 2:10 P. M., temp., 103.8°; 4:30 P. M., 

 temp., 103.5°. 



From Dec. 27 to Jan. 14 her temperature was taken several 

 times each day, ninety times altogether. Only twice was it 

 found below 102.2°, the maximum being 105.3°. No other 

 effect of poison manifest until Dec. 28 when I noticed a trem- 

 ulous motion of her sides, and rapid and irregular breathing. 

 The motion of the sides seemed a sort of panting, the rate in the 

 afternoon about 96 per minute. The next day the panting was 

 not noticeable and never became very distinct again, except 

 when there was external cause for excitement. Jan. 4, 11:40 

 A. M., I began giving each dav some milk in which snake-root 

 leaves had soaked. Jan. 6, 9:30 P. M., she showed a sort of 

 trembling the motion being backward and forward. This has 

 been noticed infrequently since, also a little panting and lessen- 

 ing of strength. Otherwise she has seemed well. She has been 

 well fed all the time. No change of temperature can be attrib- 

 uted to withholding the poison after Dec. 29 or giving it again 

 in different form Jan. 4-7 and 11-12. No constipation. 



No. 10. A female rabbit, weight 11 ounces. Jan. 11, began 

 giving her milk in which snake-root had soaked, one third as 

 much each time as to No. 9, her weight being one-third as great. 

 She has shown similar effects. Her temperature changes help 

 to understand those of No. 9. Before removing her from the 

 warren her temperature at 3:30 P. M. was 102.9°, about like that 

 of others of her size but lower than in the larger rabbits. She 

 was carried a mile in the sleeve of a laboratory apron most of the 

 way on a warm car. In twenty minutes her temperature had 

 fallen to 99 and at 9:30 P. M.'to 98.4°. It was higher every
