about fra or six months after it is removed in large stalactitic 
masses. It is used in India for many small purposes, such 
as the manufacture of bottling wax, varnishes, &c. Dr. Bidie

Description.—the resin is transparent and of a deep 
brownish yellow to amber colour when held between the eye 
and the light, but when adhering to the tree it has a bright

about 78 per cent. of oil, ee that obtained from 
common colophony. . 
Commerce.—The high price of black dammar, about Rs. 32 
per cwt. (Beddome), precludes its use as a substitute for. 
colophony, nor can it compete with olibanum as a plaster 
material.

growing at Ceram and in the neighbouring large islands 
which produces resin so abundantly that it hangs in large 
pieces and conical tears from the trunk and principal 
branches. The resin is at first white, liquid and sticky, but
