    CIII.—Dibenzoylglucoxylose: A Natural Benzoyl Derivative of a New Disaccharide. By Frederick Belding Power and Arthur Henry Salway. In a previous communication (this vol., p. 767) it was shown that the bitter taste which characterises the leaves and stems of the Australian shrub JJaviesia latifolia, It. Br., is due to the presence of a considerable proportion of a crystalline substance, dibenzoyl¬ glucoxylose, which melts at 147—148°, and possesses the empirical formula CgsH^O^HoO. This substance appears to represent an entirely new type of naturally occurring compounds, and, since a comparatively large amount of it was available, the opportunity has been utilised of subjecting it to a complete examination. Properties of Dibenzoylghicoxylose. Dibenzoylglucoxylose is only sparingly soluble in cold water, ether, or chloroform, but readily so in alcohol or hot water. In the nearly pure condition it is best crystallised from the latter solvent, when it separates in welhformed prismatic needles, contain¬ ing one molecule of water of crystallisation. It possesses an
