evening, when at times two or three in close succession made a 

 sort of trembling. Much duller than the evening before but 

 would still move, if driven. 



At 8 the next morning she shook all over, her head moving 

 from side to side and the spasms continuing. At some of our 

 visits that day we did not see real trembling. She took some 

 milk and could still climb but showed weakness. At 5 P. M. the 

 breathing was slow and barely discernible. The next morning, 

 Nov. 29, she had taken some milk containing extract of snake- 

 root that had been boiled l^i hours. Breathing deep but of 

 normal rate — about 21 per minute. No trembling until after 

 she was made to exercise. At 11:40 A. M. more trembling and 

 violent paroxysms. At 12:30 Alton held her by the nape of the 

 neck with her back resting in his other hand so that the legs were 

 free. They quivered rapidly, continually and very plainly, the 

 trembling being intensified by bending the legs with the hand. 



At 3:40 on being held the same way, trembling did not show 

 at first but soon became plain in one hind leg and then in both. 

 Rectal temperature 101^, the same also on Dec. 4, when the 

 legs would still tremble somewhat but the eyes were normal, 

 appetite good and she was active and restless. She had become 

 tame and even familiar. No extract had been offered Nov. 30th 

 and after that she would take no milk with it in, though her 

 appetite was good. When held up some trembling could be 

 seen, mostly in hind legs, as late as Dec. 7th, though in other 

 respects she seemed well. She disappeared for a time and after 

 her return showed no more trembling or effect of the poison 

 except that she was entirely tame. She had at no time been 

 given any of the snake-root except thoroughly boiled extract. 



Dec. 14. The same cat was brought to me for further 

 experiments. She showed no trembling or anything abnormal, 

 took milk readily. The next morning I offered her milk in 

 which snake-root had soaked. She would not drink it although 

 it had been warmed and it was left with her about two hours. 

 At 10 o'clock I gave her the heart, lungs, neck and back of 

 thoracic region of a rabbit which had weighed 24 ounces and had 

 died of trembles. She began eating it at once. At 11:30 she 

 had eaten all and apparently wanted more. At 4:15 she seemed 

 eager for food but would not take milk in which snake-root had 

 been soaked, but ate the meat offered — half of liver, part of 

 abdominal muscle and head of same rabbit. No trembling that 

 day, but not examined after 4:15. 



At 8:10 the next morning when lifted by nape of neck, hind 

 legs trembled strongly and on a second trial, the right fore leg 

 also (and the left a little?). When let out of box she found 

 remains of the rabbit up on a window sill and ate part of the 

 stomach which was filled with snake-root and parts of other
