    0* 1145 neutralised 2'8 c.c. iV/10 KOH. Neutralisation value = 137. C26H5202 requires a neutralisation value of 142. This substance was undoubtedly cerotic acid. Summary. The preceding investigation of a genuine expressed oil of nutmeg has shown its composition to be approximately as follows : Essential oil . Trimyristin . Oleic acid, as glyceride . Linolenic acid, as glyceride. Formic, acetic, and cerotic acids Unsaponifiable constituents. Resinous material. 12'5 per cent. 73-0 (very small amounts 8 5 per cent. 99‘5 per cent. The unsaponifiable constituents consisted of a new compound, Ci8H2205 (amounting to about 5 per cent, of the expressed oil), together with some myristicin, CuH1208, and a very small amount of a phytosterol, C20H34O (m. p. 134—135°). Although the myristicin is a constituent of the essential oil, it was not practicable to effect its complete removal by the preliminary treatment of the fat with steam.
