reckoned by Motley in 1851 to be about 933 lbs., the export 
from Sumatra was estimated by De Vriese at 10—15 quintals 
perannum. The quantity imported into Canton in 1872 was 
returned as 3,159 lbs., value 42,326 taels, equivalent to about 
_ 80s. per lb, In the Annual Statement of the Trade of Bombay 
for the year 1872-73, 2 cwts. of Malayan camphor is stated to 
- have been imported ; it was valued at Rs. 9,141. The price in 
Borneo in 1851 of camphor of fine quality was 30 dollars per 
catty, or about 95s. per lb. (Pharmacographia.) At the ~ 
present time, good Borneo camphor is worth in India Rs. 100 
per lb. ; an inferior quality is sold at from Rs. 70—80 per Ib.
