The oil of Mastigobryum trilobatum, L. (Fam. Jungerman-niaceee or liverworts) was first prepared by C. E. Lohmann4), later in somewhat larger amount by K. Mueller5). The latter examined it somewhat more carefully.

When air dried, the plant lost 90 p. c. of its weight. When correctly distilled with water vapor, the dry plant yielded 0,93 p. c.

of an orange-yellow volatile oil, the odor of which reminded not only of that of sandal- and cedarwood, but also of pine needle oil. d16.0,945 to 0,947 (a distillate with a poor yield showed d15 0,975); [a]D +12,88° (ascertained in connection with diluted oil); S. V. 5,4. Upon saponification a semi-solid mass of acids, melting at 16°, was obtained which yielded an ether-soluble lead salt. The bulk of the oil distilled between 260 to 270°. The distillate was bluish-green in color, d20 0,946; [a]D + 25,59°; it contained 87,06 p. c. C and 12,65 p. c. H. Upon oxidation of this principal fraction with chromic acid and glacial acetic acid, a substance C10H16O (b. p. 260°) was obtained. Hence the formula C10H16 was assigned to the hydrocarbon. The higher fraction of the oil (b. p. 270 to 285°) contained 5,4 p. c. of oxygen and revealed the specific angle of rotation [a]D + 42,21° (in a 3,9 p. c. alcoholic solution).
