23, and the cardiac impacts 38, per 10 sec. The rabbit was in crouching posture. In 28 

 min., the respirations were 26, and the cardiac impacts 38, per 10 sec. The lips and 

 mouth were frequently opened and shut. In 32 min., the respirations were 24 per 10 

 sec, and jerky. The rabbit showed a tendency to fall over. In 36 min., the respirations 

 were 13, and the cardiac impacts 33, per 10 sec. The rabbit was in a sitting posture, and 

 the head often fell slowly and was raised sharply, with nodding movements. The pupils 

 measured la x soths of an inch. In 40 min., the respirations were 8 per 10 sec. 

 Frequent shaking movements of the head occurred. In 42 min., the cardiac impacts 

 could not be counted, because of the jerky respiratory movements and of frequent 

 tremors ; but they seemed to occur about 24 times per 10 sec. In 44 min., the respira- 

 tions were 14 per 10 sec. Incessant tremors, chiefly of the head, were occurring. In 48 

 min., the rabbit was lying flaccidly, with the lower jaw resting on the table. Tremors 

 were frequent, and occasionally spasmodic movements occurred, during which the animal 

 was tossed about. In 51 min., the respirations were 7 per 10 sec, and the rabbit was 

 lying quietly on the side. In 52 min., the cardiac sounds, as heard with the stethoscope, 

 were very feeble, irregular, and infrequent. The pupils measured ^ x s^ths of an inch, 

 and occasionally a gasping respiration occurred. In 53 min., the respiratory movements 

 had ceased, and the conjunctiva and cornea were insensible. 



One min. after death, no cardiac impact could be felt, nor sound heard with the 

 stethoscope. Three min. after death, the right sciatic nerve was exposed : weak galvanic 

 stimulation produced no effect when applied to it, or to the surfaces of the exposed 

 muscles ; but very strong stimulation, when applied to the nerve, excited a faint twitch 

 of the foot, and when applied to the exposed muscles, a slow and feeble contraction. 

 These conditions were present also at 7 min. after death. Five min. after death, the 

 pupils measured -jfe x 5 S oths of an inch. Nine min. after death, the heart was exposed, 

 and found to be motionless ; while galvanic stimulation, even when powerful, produced 

 no effect upon it. Twelve min. after death, galvanic stimulation of nerves or muscles 

 no longer produced any effect. Forty-seven min. after death, general rigor was present, 

 but it was strong only in the pelvic extremities. The pupils measured /o x /oths of an 

 inch. 



Experiment IX* — One-tenth of a grain of extract, suspended in 47 of distilled 

 water, was injected under the skin at the right side of a pigeon, weighing 10 oz. In 7 

 min., the pigeon vomited a large number of entire wheat grains, and repeated doing so, 

 frequently, during the following 8 min., towards the end of which time some liquid 

 excrement was passed. In 17 min., the pigeon was lying on the abdomen, the wings 

 being used to steady the body. The pupils were now dilated. In 18 min., some spasms 

 occurred, which had an opisthotonic character. In 18 min. 30 sec, respiration had 

 ceased, and the pigeon was motionless. 



One min. after death, the heart was exposed, and found to be motionless. Six min. 

 after death, galvanic stimulation, even when powerful, of the surface of the heart pro-
