Professor Wyiidham R. Duustau, f.r.s.. Director of the Im])erial 

 lustitute, furnished the following report on this substance in 1905. It 

 is printed in the " Bulletin of the Imperial Institute," Vol. III., No. 2, 

 p. 1-49 : 



"GARCINIA KESIN FROM PEKAK, FEDERATED MALAY STATES. 



"This material was forwarded to the Imperial Institute on Ijehalf 

 of the Grovernmenl oi the Federated Malay States by Mr. Leonard 

 Wrav. Curator of the Perak Museum. The specimen was accompanied 

 Ijv a letter, giving the following information with regard to the extrac- 

 tion and preparation of the resin : 



"The resinous substance is the dried sap oi a Garcinia. The sap 

 is obtained bv making incisions in the bark of the trees. It is then 

 boiled until it is as thick as cream, when a little turpentine is added, 

 and it is ready for use as varnish, being applied to the wood by means 

 of a pad of cloth. 



" As pi-epared, it is an emulsion of a jjale yellow colour ; if boiled 

 till all the Avater is evaporated it solidifies, and cannot be dissolved 

 ai'ain with turpentine ; Ijut if w^ater is added at once it may again be 

 made into an enudsiou. It will only keep in good condition for a few 

 days, fermentation of the watery portion of the sap readily setting in. 



•• This Malay varnish is, Avhen dry, nearly white, very hard and 

 l)rilliant. Ijeing ([uite ecpial to the Japanese lacquer. The tree which 

 vields it is a wild one, and as it fruits freely there should be no difficulty 

 in planting it. 



• CHEMICAL EXAMINATION. 



" The sample of this product forwarded has been examined in the 

 Scientific and Technical Depai-tment of the Imperial Institute. The 

 specimen weighed about 4 ounces, and. consisted of a semi-solid resin 

 contained in a porticm of a bamboo stem. Internally tlie material was 

 soft and opa(j[ue, and had a pale yellowish colour, and an odour re- 

 sembling that of "t'ung" oil: but externally it was dark-brown in 

 colour, and was covered by a \ery thin layer of brittle material, prob- 

 ablv produced by the action of the atmosphere on the resin. This hard 

 outer layer, which is probably identical with the insoluble resin pro- 

 duced by evaporating the whole of the water from the sap, constituted 

 oulv a minute proportion of the whole: it was insoluble in turpentine 

 oil and the usual solvents, but the small amount obtainable precluded 

 its further investigation.
