Lemarie (_Bulletin Imp. Inst._, 1903, p. 206) states that this fat is used in the place of cocoa-nut oil in the manufacture of soap. Lewkowitsch (_Analyst_, 1905, p. 395) examined a large sample of dika fat obtained from seeds of _Irvingia bateri_ (South Nigeria) and gives the following data:-- ____________________________________________________ | | | | | | Saponification | Iodine | Titre, | Unsaponifiable, | | Equivalent.[9] | No. | deg.C. | Per Cent. | |________________|________|________|_________________| | | | | | | 229.4 | 5.2 | 34.8 | 0.73 | |________________|________|________|_________________| _Baobab-seed Oil._--Balland (_Journ. Pharm. Chem._, 1904, p. 529, abstracted in _Journ. Soc. Chem. Ind._, 1905, p. 34) states that the natives of Madagascar extract, by means of boiling water, from the seeds of the baobab tree, a whitish solid oil, free from rancidity, and possessed of an odour similar to Tunisian olive oil. He suggests that it may, with advantage, replace cocoa-nut oil in soap manufacture. _Persimmon-seed Oil._--Lane (_J. S. C. Ind._, 1905, p. 390) gives constants for this oil which he describes as semi-drying, of brownish yellow colour, and having taste and odour like pea-nut (arachis) oil. The following are taken from Lane's figures:--
