of cultivation and the eneroachments of the "WTiites. The 
Carihs and the Aniacas procure fire-arms at Essequiho and 
Demerara; and when the traffic of American pipes (poitos) 
Was most active, adventurers of Dutch origin took part 
in these incursions on the Paragua, the Ercvato, and the 
Ventuario. Man-hunting took place on these banks, as 
heretofore (and probably still) on those of the Senegal and 
the G-ambia. In both worlds Europeans have employed the 
same artifices, and committed the same atrocities, to main- 
tain a trade that dishonours humanity. The missionaries 
®f the Carony and the Orinoco attribute all the enls they 
suffer from the independent Caribs to the hatred of then' 
iieighbours, the Calvinist preachers of Essequibo. Their 
Works are therefore filled with complaiiits of the seeta 
diabolica de Calvino y de Lutero, and against the heretics 
of Dutch Guiana, who also think fit sometmes to go on 
missions, and spread the germs of social life among the 
savages.

which the industry of the Catalonian Capuchins has 
rendered the most celebrated is the tree that furnishes the 
Cortex angostursB, which is erroneously designated by the 
name of cinchona of Carony. We were iortunatc enough 
to make it first known as a new genus distinct from the 
cinchona, and belonging to the family of meliace®, or oi 
zanthoxylus. This salutary drug of South America was 
formerly attributed to the 'Bnicea ferrugiiiea which grows 
in Abyssinia, to the Magnolia glauca, and to tlje Magnolia 
plumieri. During the dangerous disease of M. Bonpland, 
M. Eavago sent a confidential person to the missions ot 
Carony, to procure for us, by favour of the Capuchins of 
Dpata, branches of the tree in flower, which we wished to 
be able to describe. We obtained ver^' fine specimens, tiie 
leaves of which, eighteen inches long, diffused an agreeable 
aromatic smell, soon perceived that the cwpdfe (the 
mdigenous name of the eascarilla or coi'leza del Aiigostur^ 
forms a new genus ; and on sending the plants of the 
Orinoco to M. Willdenouw, I begged he would dedicate 
this plant to M. Bonpland. The tree, known at present by 
the name of Bonplandia trifoliata, grows at the distance of 
five or six leagues from the eastern bank of the Carony, at
