kapok oil in Marseilles for soap making, the American Per- 
fumer * states: 
* * * The seed is treated in two mills, both of which are chiefly 
devoted to the crushing of other seeds. Only one pressing is the rule, 
although in some cases hot water is poured over the residue, which is then 
pressed again. The oil is then filtered, but it requires neither bleaching, 
deodorizing, nor any other treatment. In the Marseilles mills the average 
yield in oil from this seed is about 15 per cent. The price of the oil 
follows closely that of industrial peanut oil. It takes about 16% pounds 
of kapok to make a gallon of oil. 
Lewkowitsch + says the seeds have the following average 
composition :
