    CCXVI.—The Constitution oj Eriodictyol, oj Ilomoerio- dictyol, and of Hesperitin. By Frank Tutin. In a paper communicated to the meeting of the American Pharmaceutical Association, held at Indianapolis, Ind., in Septem- ber, 1906, Dr. F. B. Power and the present author described the isolation of two crystalline substances of phenolic nature from the leaves of Eriodictyon Californicum (Hooker and Arnott), Greene (Proc. Amcr. Pharm. Assoc., 1906, 54, 352). These two compounds were designated eriodictyol and homoeriodictyol respectively, the former having been proved to possess the formula C15H1206, whilst the composition of the latter was shown to be C16H1406. In a subsequent communication (Trans., 1907, 91, 887) it was noted that there are certain similarities in the properties of homoeriodictyol and its isomeride, hesperitin, which suggested that those two compounds were structurally related. Experiments sup- ported this view, for, whilst hesperitin yields isoferulic acid (3-hydroxy-4-methoxycinnamic acid) and phloroglucinol on hydrolysis (Tiemann and Will, Bcr., 1881, 14, 970), homoeriodictyol, when
