1878.] the Poisonous Principle of Urechites Suberecta. 321 



12.0 o'clock. Attempted repeatedly to vomit, but brought up 

 nothing. 



12.20 p.m. Attempted repeatedly to vomit, but brought up nothing, 

 the retching not so violent; up to this time had been restless, now 

 seemed fatigued and disposed to lie down. 



12.35 p.m. Again ineffectually tried to vomit, continuing its efforts 

 for five minutes. 



12.45 p.m. Yomited violently a yellow frothy liquid. 



I. 45 „ Passed urine, tried to vomit, appeared sleepy. Dribbled 

 much from its mouth. 



2.20, 3.20, and 4.20. Yomited violently a yellow frothy liquid. 

 This vomiting was repeated three times between 4.20 and 11 o'clock 

 p.m., when it was last seen alive. At 5 o'clock next morning it was 

 found dead, stiff, and cold. It had evidently died in convulsions, the 

 pupils were so expanded as to almost obliterate the irises. Death 

 must have occurred within sixteen hours of the injection. On being 

 opened, a generally congested state of the vessels of the viscera and 

 brain was found, the intestines, as usual, tense, and the auricles and 

 right ventricle of the heart gorged with blood, while the left ventricle 

 contained but very little. 



Between two and three hours after the injection a mouse was put 

 with the cat, it immediately caught and killed it, but neither played 

 with nor ate it. 



Experiment XXI. 



Injection of gr., = 1*3 mgm., pure hydrated urechitoxin, followed 

 twenty-four hours afterwards by a second injection of gr. of the 

 same sample of poison. The cat used was a very strong one, weigh- 

 ing 6 lbs. 6 ozs., it was last fed fourteen hours before the first in- 

 jection. 



10.20 a.m. Injected gr. urechitoxin, dissolved in \ cub. centim. 

 (40 per cent.) spirit, under skin of neck. 



10.35 a.m. Very restless, seemed to want to pass faeces and urine. 

 10.40 „ Passed faeces. 

 11.6 „ Passed urine. 



11.15 ,, Yomited violently, bringing up partly digested food. 

 Panting much as if very hot. The usual licking of lips preceded the 

 vomiting, after which the cat appeared much easier. 



II. 17 a.m. Passed faeces. 



11.20 „ Again panting, lying down extended, respirations over 

 100 per minute and irregular. 



11.25 a.m. Yomited much partly digested food, afterwards became 

 very restless, still panting. 



11.30 a.m. Lay down extended, panting, pupils appeared dilated, but 

 were quite sensitive to light. Soon got up, restless again.
