The impure acids are next distilled in copper stills heated by steam injected at a temperature of 600. The dark residue in the retorts is made by pressure to yield further portions of oil at the close of the distillation, and the black solid mass which remains is used for fuel. The distilled fat, when cooled to 50 or 54, is broken into cakes 18 in. square and about If thick, which are distributed upon squares of coir or cocoanut matting, and these being piled upon each other are submitted to the action of a hydraulic press at a temperature of 75. The fat thus obtained may be run at once into candles for the European markets ; but for tropical climates it is again submitted to pressure at a temperature of 120. The soaps made with palm oil retain the natural agreeable odor of the oil. In Africa palm oil is eaten to some extent by the natives as a sort of butter. In medicine it is recognized as an emollient, and employed sometimes in friction or embrocation, though possessing no specific virtue over other oleaginous substances. PALM SUNDAY. See HOLY WEEK.
