28 Dr. Hancock on the Angusiura Bark Tree. 



made with this it seems much inferior to the fresh bark or its 

 recent infusion. 



The natives also use the bruised Bark as a means for intox- 

 icating fishes (Barbasco), which affords a very singular coin- 

 cidence with what is mentioned by Dr. Saunders, of the same 

 use being made of the Cinchona Bark by the Peruvian Indians. 



I am fully convinced, from ample experience of the virtues 

 of this Bark, that it is one of the most valuable febrifuges we 

 possess, being adapted to the worst and most malignant bilious 

 fevers, while the fevers in which Cinchona is chiefly adminis- 

 tered are simple intermitients, for the most part unattended 

 with danger. 



May I be allowed to hope that, with the assistance of the 

 above description and the accompanying plate, the GALIPEA 

 officinalis may be found on the higher lands (continuation of 

 the Carony mountains) near the falls of the rivers Demerary 

 and Essequebo, and that the Bark may be thence imported in 

 a state much more fit for the London market than it is now to 

 be had, coming as it does through a circuitous route, the length 

 of which cannot but impair its properties. 



I have thus endeavoured to lay before the Society the results 

 of my observations, humble as they are, and hope that, though 

 insignificant in themselves, they will lead to future investiga- 

 tions into the medicinal properties of this valuable remedy, 

 which I am fully convinced are not to this time sufficiently 

 known or appreciated.
