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:—

Chinese vegetable tallow is the name given to the fat which is found coating the seeds of the "tallow tree" (Stillingia sebifera) which is indigenous to China and has been introduced to India where it flourishes. The following is a typical sample:—

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:—

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.
