    easimiroic acid, C23H2g04(0H)'C02H (m. p. 207°; [a]D — 86'8°). The following derivatives of this acid were prepared: silver casi- miroate, C23H2905-C02Ag; methyl casimiroate, C^HoaOj-CCMJHg (ra. p. 108—110°); and acetylcasimiroic acid, CogHjgO^O • COCHg) • COoH ; (v) a yellow, phenolic substance, ClflH12Oe (m. p. 215—218°). It may finally be noted that the results of the present investiga- tion of Casimiroa seed have afforded no evidence of the presence of a definite glucoside or a so-called “ glucoalkaloid,” as has previously been affirmed, and physiological tests conducted with animals have likewise failed to confirm their reputed hypnotic or toxic properties.
