Upon distillation of the needles of Sequoia gigantea, Torr. (Wellingtonia gigantea, Lindl.), the giant of California, obtained from a tree cultivated in Zurich, G. Lunge and Th. Steinkauler1) obtained a volatile oil which congealed in part at ordinary temperature and which consisted principally of a hydrocarbon C10H16 boiling at 155°. The sp.gr. of the hydrocarbon was 0,8522; [a]j + 23,8°. When hydrogen chloride was passed into the hydrocarbon, a white chlorhydrate (presumably pinene chlor-hydrate) consisting of white needles resulted.

Fraction 227 to 230° had a sp. gr. of 1,045, an angle of rotation of -+- 6° and its odor reminded of that of peppermint oil. The results of the elementary analysis corresponded with the formula C10H20O3. Between 280 and 290° a small amount of heavy yellow oil passed over that had an empyreumatic-aromatic odor.

Furthermore, the oil contains a hydrocarbon, named sequo-jene, that boils between 290 and 300° (uncorr.), is odorless, crystallizes in small lamina? and melts at 105°. Its composition is probably expressed by the formula C13H10, an isomer of fluorene.
