a matter of fact, planting has already ceased; and exportations are 
of cinchona products must rise. The invention of the new oil p 
of Messrs. Wood and Gammie, and the free publication of it by Govern- 
ment, will no doubt contribute materially to maintain them permanently 
below the rates which have been hitherto considered as no 
cinchona industry, the Government estate could not ; 
aud from a commercial point of view, the past year has not been so 
good as many previous years when prices were h ut inasmuch as 
quinine has been materially cheapened (and thus put more within reach 
of the masses), the result is, I think, gratifying.” :

Quinologist to the Government of Bengal. 
* At the time [ received the appointment of Quinologist under the 
Government of Bengal (1873), I was instructed by the Secretary of 
State to give my chief attention to the production on a large scale of a 
cheap and efficient febrifuge from the cinchona bark grown in British 
Sikkim ; and I was specially directed to consider the suitability of the 
method which had been proposed by Dr. De Vrij for this purpose. It 
was in accordance with these instructions that the manufacture of the 
preparation now known as ‘cinchona febrifuge’ was estab 
ungpoo. This preparation is made exclusively from the bark of C. 
succirubra, which at that period was the principal product of saa
