pear to thrive, and the cuttings taken from them all died. On the 
approach of the cold weather they were sent to Darjeeling, but 
three only reached the station alive and these survived but a short 
time, having been killed by the cold of the winter. 
This can hardly be deemed a fair trial. The plants were too 
few in number. They were detained many months in the uncon- 
genial climate of Lower Bengal. They were weakened by cuttings 
and change of place and then suddenly transported at the approach 
of winter to an elevation 6,0p0 or ^,000 above the plain in which 
they had passed the hot season and the rains. Accordingly 
the Medical Board of Bengal again addressed the Government of 
Indiaf urging the prosetiution of the experiment upon a more ex- 
tended scale and recommending that it should be undertaken in si- 
tuations better adapted to the natural habits of the tree, such as 
the Neilgherries and the hilly regions of Sylhet, Chittagong and 
the Tenasserim Provinces. 
Of the result of this application we are not informed. 
About the same period, the subject of the Cinchonas attracted 
the attention of the French Government. In 1843 M. de Castel- 
nau having been appointed to conduct an expedition for scientific 
purposes into Central South America, M. Weddell was associ- 
ated with him at the instance of the Musee D'Histoire Naturelle 
for the prosecution of researches in Natural History. His atten- 
tion was directed to the investigation of several interesting subjects 
of botanical inquiry among which the history of the Cinchona oc- 
cupied a prominent place. After working in concert with M. 
de Castelnau for two years, he separated from him and pursued an 
independent course of inquiry until 1848. It was during this pe- 
riod in 1845-47 that he obtained the valuable information regard- 
ing the Quina yielding trees which he has given to the world in his 
Histoire Naturelle des Quiyiquinas which forms the standard as well 
as the most recent work on the subject. 
In the introductory chapter Mr. Weddell gives a sketch of the 
history of the drug previous to the period of his own discoveries,
