NATURAL HISTORY OF THE CINCHONAS.

the most efficacious method ; but is it not to be feared that 
the disproportion between the consumption and production 
is already too great to admit of the balance being thus re- 
stored ? and moreover, are not our wants too pressing to 
give way to considerations affecting only the future ?* 
There remains then cultivation, and this must be resorted 
to. If there be a tree which is worthy of being acclimated 
in a French colony, it is, certainly, the cinchona, and pos- 
terity will be grateful to those who may succeed in putting 
this plan into execution. 
In a subsequent article we propose noticing the particular 
notions of M. Weddellon the classification of the cinchonas ; 
to which will be added the description of new species for 
which science is indebted to the learned researches of this 
naturalist. — Phurm. Journ.fro?n Journ. de Pharmacie et

* In support of this view of the subject we may cite the case of the 
Company of La Paz, to whom the Bolivian government conceded th« 
monopoly of the commerce of the cinchonas of Bolivia, with thepowei 
of annually exporting 4,000 quintals or 40,000 Spanish pounds. The 
restriction imposed in this case was never observed, and complaints 
have been made that the quantity allowed to be exported has been 
greatly exceeded. What would it be, then, if the restriction were en- 
tirely removed, as they are in most other parts, and especially in Peru, 
where the exportation, during some years, has attained to an extent 
which is almost incredible. 
In New Granada, at the time when the commerce of cinchona bark 
was carried to the greatest extent, that is to say at the commencement 
of this century, the quantity exported from Carthagena alone amount- 
ed in one year, 1806, to the enormous extent of 1,200,000 pounds. 
In the present day, on the contrary, scarcely any is exported.
