330 Mr. J. J. Bowrey on the Physiological Action of [Apr. 11, 



10.40 a.m. Poison given on empty stomach. 

 11.0 ,, Vomited clear liquid mixed with, white froth. 

 11.10 „ Do. do. 



11.20 ,, Do. yellow liquid mixed with yellow froth. 



11.40 „ Do. do. 



12.5 p.m. Do. do. 



The vomiting very violent and accompanied with cries. 



I. 10 p.m. Made violent attempts to vomit, but brought nothing up. 

 Very weak. 



3.4 p.m. Vomited violently white frothy liquid. 



7.0 „ Do. do. immediately after- 



wards convulsions came on, in which it died. 



After 1 o'clock it gradually became weaker, and was very unwilling 

 to move. When the effects of the poison were well developed, the skin 

 of neck was observed to be of a bright pink colour ; the colour was 

 easily seen on the neck, as the skin was very thin there ; when the 

 poison was given the skin was almost colourless. The eyes were not 

 affected, their pupils remaining sensitive to light ; in death, however, 

 they enlarged, the irises becoming mere lines. 



Experiment XXX. 



A dose of y 1 ^ gr. of pure finely powdered urechitin was distributed 

 on two small pieces of meat, which were then given to a cat ; one piece 

 was swallowed, the other rejected after being chewed (no doubt the 

 poison was tasted) ; a considerable proportion of the dose, however, 

 must have been swallowed even from that second piece of meat, for 

 the poison lying on its exterior would be swept off in the act of 

 chewing. 



II. a.m. Dose given on empty stomach. 

 11.40 „ Vomited. 



12.0 Do. 

 12.15 p.m. Do. 



1.0 ,, Do. but not again up to the time of leaving the 

 laboratory (4 p.m.). After mid-day it remained in the same spot, 

 never moving. 



Next morning it was found in the same state as when left ; there 

 were no signs of any vomiting. On being let out of its cage it slowly 

 walked to a bush, under the shade of which it remained all day. It 

 refused to eat anything. In the evening it was left under the bush. 

 Third morning — The cat was found lying in a cool place some 40 feet 

 from the spot where it was left on the second day. It was very weak, 

 and had lost the power of locomotion completely, but could move its 

 limbs languidly. At 10 a.m. it was carried into the laboratory, that it 

 might be more closely watched. If undisturbed it lay perfectly still, 

 asleep. Liquid ran from its mouth. Pupils sensitive to light, but
