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 broM'n 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 ?). 



licsm of Liquidamhar formosana Hance — This tree, which we 

 suppose may be the Sty rax liquida folio niinore, 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 Pmi-tsao^ is, we presume, this species. 



Hesm of AUlngia exceJsa Noronha {Liquidamhar AltingianaBl) 

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

 cent tree of the Indian Ai^chipelago, 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, procured by 

 boring the stem and applying fire around the trank.
