_Mowrah-seed Oil._--The mowrah-seed oil now offered for soap-making is derived from the seeds of _Bassia longifolia_ and _Bassia latifolia_. It is largely exported from India to Belgium, France and England. The following are the results of some analyses made by us:-- _________________________________________________________ | | | | | | Saponification | Acidity | Titre, | Refractive | | Equivalent. | (as Oleic Acid) | deg.C. | Index at | | | Per Cent. | | 60 deg.

The following is a typical sample:-- _____________________________________ | | | | | Saponification | Acidity | Titre, | | Equivalent | Per Cent. | deg.C. | |________________|___________|________| | | | | | 280.2 | 5.24 | 52.5 | |________________|___________|________| The seeds of the "tallow tree" yield an oil (stillingia oil) having drying properties. _Borneo Tallow._--The kernels of several species of _Hopea_ (or _Dipterocarpus_), which flourish in the Malayan Archipelago, yield a fat known locally as Tangawang fat. This fat is moulded (by means of bamboo canes) into the form of rolls about 3 inches thick, and exported to Europe as Borneo Tallow. A sample tested by one of us gave the following data:-- ___________________________________________ | | | | | Saponification | Acidity | Titre, | | Equivalent. | (as Oleic Acid) | deg.C. | | | Per Cent. | | |________________|_________________|________| | | | | | 292 | 36 | 50.8 | |________________|_________________|________| _Kapok oil_ is produced from a tree which is extensively grown in the East and West Indies. The Dutch have placed it on the market and the figures given by Henriques (_Chem. Zeit._, 17, 1283) and Philippe (_Monit. Scient._, 1902, 730), although varying somewhat, show the oil to be similar to cotton-seed oil. VARIOUS NEW FATS AND OILS SUGGESTED FOR SOAP-MAKING.
