Origin and Production. In addition to Acacia Fames/ana, described on p. 588, Acacia Cavenia, Hook, et Arn.2) is likewise cultivated in southern France. This species demands less care and yields a larger harvest of flowers the odor of which, however, is not so delicate. The trade name of A. Ca-venia is Cassier Romain, presumably because this shrub was brought to Cannes from Italy about 100 years ago. As stated, one of the advantages is that A. Cavenia is less sensitive and demands less care than A. Farnesiana, which must be trimmed annually in March, whereas A.davenia demands no such treatment.

The plant is reproduced by cuttings. As soon as these have taken root they are transplanted3). During the first summer after transplanting, the shrubs bear flowers. In 1910 the price of 1,5 fr. pro kg. was paid for these in Grasse4).

The perfume is obtained according to the same method by which that of A. Farnesiana is produced.

Composition6). The extract investigated had been obtained by extraction of the flowers with petroleum ether. From this the oil was obtained by distillation with water vapor and shaking out the aqueous distillate with ether. When shaken with dilute sodium hydroxide solution the oil yielded 5,5 p. c. phenols, 8,8 p.c. non-phenols and 1,1 p.c. salicylic acid, computed with reference to the extract. In another instance 3 p.c. of phenols, 4,5 p.c. of non-phenols and 1,66 p.c. salicylic acid were obtained.

2) In Grasse the perfume of Acacia dealbata, Lk., known there as mi-mose, is extracted and utilized, whereas A. floribunda, Willd. (A. longifolia, Willd.) and A. Melanoxylon, R. Br. are not suited to this purpose. Berichte von Roure-Bertrand Fils April 1904, 60.

The mixture of phenols consists of 90 p.c. of eugenol (m. p. of benzoyl compound 69 to 70°). The salicylic acid found (m. p. 156°) is present in the oil as methyl ester. The following substances were also identified; benzaldehyde (m. p. of semicarbazone 214°), benzyl alcohol (m. p. of phenylurethane 77 to 78°), geraniol (m. p. of diphenyl urethane 81°), anisic aldehyde (m. p. of anisic acid 184°; of semicarbazone 203 to 204°), eugenol methyl ether (m. p. of veratric acid 178°), and a ketone with a violet-like odor. Presumably linalool and decylic aldehyde are also present.
