The wood of Fusanus spicatus, R. Br. (Santalum cygnorum, Miq.) is shipped from Fremantle, Western Australia, and is sold in the Singapore market as Swan river sandal wood. In India and China it is used as a substitute for Indian sandal wood from Santalum album. According to E. j. Parry3), at least three other closely related species come into consideration, viz., Santalum lanceolatum, S. acuminatum and 5. persicarium. The wood contains 2 p.c. of oil of an unpleasant resinous odor: d15o0,9534) to 0,9653); aD + 5°20'.

Hence West Australian sandal wood oil differs considerably in properties, and presumably also in its composition from East Indian sandal wood oil and can never be used as a substitute for the latter. .

As early as 1875 the oil was distilled by Schimmel & Co. in Leipzig. Later the distillation was taken up in Fremantle5).

As saponification numbers Parry3) found 1,1 to 1,6. After acetylation he obtained saponification numbers corresponding to a santalol content of 75 p.c. Whether the alcohol of the West Australian sandalwood oil is identical with santalol or not must, however, first be ascertained.
