From a lot of sandalwood from Guiana, about the botanical origin of which nothing could be ascertained, P. Jeancard and C. Satie1) distilled several oils the constants of which fluctuated between the following limits: d15o 0,9630 to 1,0122; a + 0°30' to - 6°; S. V. 13 to 65; E. V. after acetylation 65 to 117; soluble in 1,5 to 12 vol. of 75 p. c. alcohol and in 0,8 to 1,1 vol. of 80 p.c. alcohol. The oils contained from 59 to 80 p.c. of a fraction that boiled between 155 and 160° (20 mm.) (d26o1,024 to 1,037; a _ 4°20' to - 6°; soluble in 1,8 vol. of 70 p.c. alcohol).

The properties of the oil depends very largely on the nature of the material from which it is prepared. For this reason oils were distilled from the branches (1), the trunk wood (II) and from pieces of the bark (III), the constants of which are herewith tabulated.

Fraction 155 to 160° (20 mm.) contained a constituent which boiled between 155 and 159° (20 mm.) (d23ol,0378; aD - 6°; soluble in 1,6 vol. of 70 p.c. alcohol, in 2,7 vol. of 65 p.c. alcohol and in 6,5 vol. of 60 p.c. alcohol) which jeancard and Satie have named maroniol and which probably is a tertiary alcohol. The alcohol cannot be acetylated according to the ordinary method. When heated with acetic acid anhydride for an hour, a saponification value of 147 was found, after three hours one of 168, and after five hours one of 189.

In 1910, Schimmel & Co.1) also distilled Guiana sandalwood. According to Dr. Giessler, Custodian at the Botanical Institute of the University of Leipzig, the wood belongs to the family Lauraceae and is probably derived from one of three species of Acrodiclidium or Ocotea. The constants of the oils were:
