    1.45. There are distinct muscular twitches in the shoulder. General tremor. 1.47. There are twitching movements of the back. 2.8. Has been standing perfectly still. Is now pawing and licking his lips. Vomits. 2.10. Vomits again, but licks up part of what he had ejected. 2.22. Has been continually vomiting. The ejection consisted at first of food, afterwards of tenacious mucus. He now lies down apparently exhausted. He is still trying to vomit, but can bring nothing up. He tries to rise, but cannot. Convulsive struggles occur. 2.25. Breathing has ceased, but the cornea is still sensitive. Convul- sive attempts to vomit. 2.27. Cornea insensible. Heart is still beating strongly. Death soon followed. Experiment II. A young rabbit, weighing 900 grammes, was used. An incision had been previously made through the skin of the neck and the wound again sown up, but the animal was otherwise uninjured. Two drops of cobra- poison, weighing 12 centigrammes, were diluted with 1 cubic centimetre of water. At 4.6 the diluted poison was ejected under the skin of the left hip. 4.7. Washed out the watch-glass in which the poison had been placed with water, and injected it under the skin of the back. The animal sat quiet after the injection, occasionally licking its fore paws. 8' 30. Bespiration seems hurried. The rabbit occasionally makes a jerking motion with its hind feet. 10'. Has been restless, running about, occasionally licking its fore feet. 13' 30. Still very restless, and when held makes convulsive efforts to get oway. Ears are much congested. 17'. The animal is now quiet. Its ears are no longer congested. About 20'. Quiet, with occasional starts. DisincHned to move, but can walk quite well. 25'. Movements seem difficult, and hind legs seem weak when it tries to walk. 26'. Paralysis of hind feet is increasing. 26' 15. The rabbit lays its head down on the table. 28'. When laid on its side it merely makes a few sh'ght movements with its fore paws and then lies still. The eyes remain in a half-closed condition, and have done so for some time. When the cornea is touched the head gives a jerk, but the eyelids move very little. Bespiration slow and laboured. 4.30. The chin is twitched inwards, the sternum once or twice, the hind feet at the same time being twitched backwards. The eyes open widely. Slight convulsive extension of limbs. 4.31. Bespiration has stopped, cornea is insensible; thorax opened
