Fusanus acuminatus, R. Br. (Santalum Preissianum, Miq.; 5. acuminatum, A. DC; 5. cognatum, Miq.; 5. lanceolatum, Schlecht.), known as "Quandong" in Australia, bears edible fruits which are known as native peaches6). The wood of the tree is dark brown in color, exceedingly dense and tough as to texture, and very hard and heavy. It contains 5 p.c. of a viscid, cherry-red oil, the sp. gr. of which is 1,022 at 15°. Its odor is agreeably balsamic reminding one of roses. Upon standing, the oil separates crystals which, upon re-crystallization, are obtained as colorless prisms melting at 104 to 10501).

Composition. The crystalline constituent of the oil has been examined by A. Berkenheim2). He found its melting point to be 101 to 103° and proposed C15H2402 as its formula. The substance is an alcohol, the acetic ester of which crystallizes in hexagonal plats that melt at 68,5 to 69,5°. With phosphorus trichloride a derivative C15H230 CI is obtained that melts at 119 to 120,5. Phosphorus pentachloride does not act on the alcohol. The methyl ether obtained with the aid of the sodium compound is liquid. By means of potassium permanganate the alcohol is oxidized to the acid C7H1402 which also is liquid.
