" Weddell, in the Introduction to his * Histoire Naturelle des 
Quinquinas,' says that his attention has been given to all sorts of 
Quinquinas. These are his words L'immense accroissement 
pris par le commerce des Quinquinas dans ces parties, rendait en 
quelque sorte necessaire un travail aleur sujet. Aune epoque aussi 
ou la consommation de ces ecorces, et surtout de leur principe fe- 
brifuge, la Quinine, devient de plus en plus considerable, je crois 
qu'il pent etre utile d'appeler I'attention sur les ecorces qui unjour 
devront remplacerla Quinquina Calysaya, dontPepuisement devient 
de plus en plus imminent. Ces especes, si elles sont beaucoup moins 
riches en principes actifs, nous offrent encore, par leur abondance, 
quelque securite, centre la chance prochai»ie de nous voir prives du 
medicament le plus precieux du regne vegetal.* 
Several Dutch naturalists, whose zeal in advancement of science 
for the good of mankind and the glory of their country is above all 
praise, have, for more than twenty-five years, urged lipon the Go- 
vernment, both at home and in India, the transplantation of the 
Quinquina-tree from South America to Java. Those gentlemen 
have been Messrs. Blume, Korthals, Reinwardt, G. J. Mulder, Mi- 
quel, Fromberg, Vrolik, and others. 
" It will be superfluous to say that successive Ministers for the 
Colonies have considered these propositions, and all who were offi- 
cially called to it, and could throw light on the subject, have shown 
tjieir interest in, and their desire for, the accomplishment of this ob- 
ject. 
" Some of these naturalists have thought it probable that after 
some years, if the Quinquina-tree should be exhausted in South 
America, the culture of it might succeed in Java. Others have 
thought that neither pains nor money should be spared to transplant 
from Peru to Java a tree which would grow as luxuriantly there as 
in America. 
" The desirableness of the transplanting was continually kept in 
remembrance ; but the Government supposed the thing impractica- 
ble. The wish to obtain seeds of this tree, through the Dutch con- 
suls in different States of America, was disappointed, the difficulty 
of obtaining them being so great, on account of the distance of their
