,8,,. POISONOUS SECRETION OF BATRACHIANS. 189 



Phrynine has since been proposed for the latter (Fornara, 12). Claude 

 Bernard (2) had previously alluded to the fact that the Indians of 

 South America use Batrachian poison, with the same effect as curare, 

 for poisoning spears and arrows which are specially used against 

 monkeys. This Dendvobates tinctoriiis (Fig. 2) derives its name from the 

 property it is said to possess of "dyeing" parrots. The method 

 employed for that purpose consists in removing part of the feathers of 

 green parrots, and injecting the bare skin with the blood of the 

 Batrachian ; the feathers are regenerated green or yellow on these 

 spots, and artificial varieties are said to be thus obtained.
