et des feuilles adultes, et sur la presence, ä l'etat jeune, de pe- 

 tites stipules dentiformes caduques. 



II publie ä la suite: 1. les notes prises sur le vif par M. Le Testu 

 sur ces trois especes et sur un Carpodinus pour la determination duquel 

 on attend des echantillons complementaires, et qui serait susceptible de 

 donner du caoutshouc de bonne qualite; 2. une notice, redigee sur place, 

 sur les procedes d'exploitation: le meilleur consiste ä saigner la liane tout, 

 les 50 ä 70 centimetres, ä coaguler par l'eau salee, et ä enrouler en 

 boules le latex concrete. — La Liane ainsi traitee persiste. Malheu- 

 reusement, pour obtenir un rendement plus grand, les indigenes decou- 

 pent parfois la liane en troncons et coagulent le latex extrait par la chaleur. 

 Le produit est moins bon, et la liane est detruite. 



Le caotuchouc est encore produit mais en petite quantite par trois 

 arbres: Ficus Vogelii, Klckxia elastica, et un autre indetermine, nomme 

 Dodo en langage Nagot. Henri Hua.
