Effect of Amorphous Uvechitoxin on Gats. 

 Experiment XXIV. 



This and the three following experiments were all made with the 

 same sample of amorphous urechitoxin, a sample from which the 

 crystalline urechitoxin had been removed. 



Injected y^-o gr. amorphous urechitoxin in } cub. centim. of spirit (40 

 per cent.) under skin of neck of a full grown cat weighing 4 lbs. 12 ozs. 

 The only effect observed was that the animal became dull and sleepy, 

 and would eat on the day of injection, or on the two following days, 

 thus fasting for three days. It ate a little, very little, on the fourth 

 and fifth days, but still remained in the same sleepy state, taking no 

 exercise. After that it rapidly recovered. There was no vomiting. 



Experiment XXV. 



Injected gr. amorphous urechitoxin in \ cub. centim. (40 per 

 cent.) spirit under skin of neck of cat weighing 5 lbs. 14 ozs. 



The only effect noticed was that the cat was sleepy, dull, and ap- 

 parently weak, and did not recover its appetite for full five days after 

 the injection of the poison. There was no vomiting.
