over wMcIl are placed inverted bowls, the steam rising into these 

 bowls carries with it the camphor, which is deposited and forms 

 into masses or crystals. The other process is by placing chips 

 of the wood and branches in covered iron vessels, in the covers 

 of which are placed cut np straw and rushes. Heat is then

Camphor, Sumatra and Bornean, the produce of Dryo- 

 balanops aromccHca, a tree of the Dipterocarpaceae family, 

 found chiefly in Sumatra and Borneo. It is a noble 

 tree, often growing to a height of 90 feet before branch- 

 ing. The bark separates from the stem in large ilakes. 

 The foliage is very dense, forming a fine head. To obtain the 

 camphor the tree is felled and cut into blocks, which are split 

 longitudinally, when the camphor is found in a concrete state in 

 the fissures of the wood, it is white and transparent. The 

 -q^uantity yielded depends upon the age of the tree ; middle-aged 

 trees yield from 10 to 12 lbs. A more or less quantity 

 of essential oil is also found in the cavities of the wood, 

 which on being crystallised, yields some resin, and a small 

 quantity of camphor. This camphor and oil are highly 

 valued in China and Japan, as also in Borneo and Sumatra, 

 and are used chiefly for medical purposes in various ways, 

 and for various complaints, and also for embalming the bodies 

 of tlie rajahs.
