Wood, yellow inside (heartwood), white outside (sapwood). The heartwood only should be used, which natively is obtained by felling trees of .3 M. (12') diameter, hacking off sapwood, or allowing these trunks to remain on the ground until sapwood is eaten away by ants, thereby becoming 10-20

Oil of Santal. - This volatile oil, distilled from the wood, is a pale yellow, somewhat thick liquid, characteristic odor and taste of sandalwood, soluble in 5 vols. of 70 p. c. alcohol, solution being slightly acid, sp. gr. 0.972, laevorotatory; contains alcohols, calculated as santalol (most important constituent), C15H26O, 90 p. c., and santalal, C15H24O, both being decomposed by distillation over P2O5 - santalol yielding santalene, C15H24, and santalal giving C15H22; also present sesquiterpene, possibly acids. Tests: 1. Australian oil, sp. gr. 0.953,
