OLEUM CAJUPUTI. 277 



have before us an excellent sample of it collected for Messrs. Wallace 

 Brothers of Statesville, N. Carolina.^ 



In Central America this exudation is far more freely produced ; 

 an authentic specimen from Guatemala in our possession is a pale 

 yellow, opaque resin of honey-like consistence, becoming transparent, 

 amber-coloured and brittle by exposure to the air. It has a rather 

 terebinthinous, balsamic odour. In the mouth it softens like benzoin 

 or mastich, and has but little taste. Another specimen also from 

 Guatemala, a thick, fluid oleo-resin, of a golden brown hue, was contri- 

 buted to the Paris Exhibition in 1878. 



The resin of L. styraciflua L. has been ascertained by Procter' to 

 contain cinnamic, but not benzoic acid. Harrison' found it to contain 

 styracin and essential oil (styrol ?). 



Resin of I/iquidambar formosana Hance — This tree, which we 

 suppose may be the Sty rax liquida folio minor e, which Ray names* as 

 occurring in a collection of plants from Amoy, is a native of Formosa 

 and Southern China, where it affords a dry terebinthinous resin, of 

 agreeable fragrance when heated. Of this resin, which is used by the 

 Chinese, a specimen collected in Formosa by Mr. Swinhoe has been 

 presented to us by Dr. Hooker. A tree figured under the name of 

 Fung-heang in the Pun-tsao^ is, we presume, this species. 



Resin of AUingia excelsa Noronha (Liquidavibar AltingianaBl.) 

 Rasamala of the Javanese and Malays — The Rasamala is a magnifi- 

 cent tree of the Indian Archipelago, Burma ^and Assam. In Java it 

 yields by incisions in the trunk an odorous resin, yet only very slowly 

 and in very small quantity ; this resin is not, or at least not regularly, 

 collected. In Burma, on the other hand, the tree affords a fragrant 

 balsam, of which according to Waring^ there are two varieties, the one 

 pellucid and of a light yellowish colour, obtained by simple incision ; 

 the other thick, dark, opaque, and of terebinthinous odour, procm-ed by 

 boring the stem and applying fire around the trunk.
