From Prof. Heckel, of Marseilles, Schimmel & Co.2) obtained a small lot of fruits with an anise-like odor. They were reported as coming from Madagascar and as being probably derived from Pelea madagascarica, Baill.3) (family Rutaceae). From these seeds 4,05 p.c. of a yellowish oil were obtained. Unlike the odor of the fruits, that of the oil reminded of anisic aldehyde rather than of anethol. This observation was verified, for, even when the oil was subjected to the temperature of a freezing mixture and inoculated with a crystal of anethol, but little anethol crystallized out, whereas the oil reacted strongly with acid sodium sulphite. The aldehyde regenerated from the bisulphite addition product appeared to consist in the main of anisic aldehyde though the presence of other aldehydes is not excluded. For a positive proof the amount was too small, only a few grams being available. The constants were: d15o0,9553; aD + 32°22'; nD20o 1,51469; soluble in 4 vol. or more of 80 p.c. alcohol.
