Poisonous effects on animals 153 



Taxin is insoluble in water — a fact which renders 

 useless all the experiments that have been made 

 with watery extracts of the leaves. Cornevin ^ 

 proved this by administering to a horse the liquid 

 from a prolonged maceration of the leaves, which 

 did not cause any untoward symptoms, while the 

 boiled leaves themselves produced death.
