THE SUPPLY OF CINCHONA BARK. 



The report that there will be a decrease in the output of the Ceylon 

 and Indian cinchona plantations during the present year has given rise 

 to considerable interest in cinchona statistics in commercial circles. 



Already the price of quinine has risen by 100 per cent, during the 

 last two months, viz., to Is 9£d per oz., and during the same period the 

 sales and resales of nuinine have amounted to about 4,000,000 oz. 

 Messrs. C. M. and C. V* oodhouse have directed attention to the present 

 position of cinchona and quinine in two circulars issued to those inter- 

 ested in this trade. 



From the tables given in these circulars it appears that during the 

 last few years the supply of cinchona has only just kept pace with the 

 demand, and has now fallen short of it, so that a still further increase 

 in the price of the bark and the alkaloid may be looked for. This en- 

 hanced value of cinchona may possibly lead to an extension of cinchona- 

 planting in India, where planters have, of late years, shown a tendency 

 to abandon it in favour of more profitable products. (Imp. Inst. Journ., 

 iv., p. 77.) 



The following tables show the amounts of cinchona produced in the 

 East Indies during the last few years and the imports into the chief cin- 

 chona-consuming countries.
