 have meant the ricinus seeds. The seeds of the Palma Christi, too, have been frequently found in sarcophagi; evidence that they had acquired a high reputation of some kind.

Hippocrates apparently tried to reduce the acridity of the seeds so as to make them more useful as purgatives. Dioscorides alludes to their purgative properties, but only contemplates the external employment of the oil in medicine. Pliny, however, is more explicit. Chapter xli., of Book 23 begins with the sentence: "Oleum cicinum bibitur ad purgationes ventris cum pari calidæ mensura." The whole passage is of interest. The following is the translation of it given in Bohn's "Classical Library" (Dr. Bostock): "Castor oil taken with an equal quantity of warm water acts as a purgative upon the bowels. It is said, too, that as a purgative it acts particularly upon the regions of the diaphragm (precordia). It is useful for diseases of the joints, all kinds of indurations, affections of the uterus and ears, and for burns, employed with the ashes of the murex; it heals itch, scabs, and inflammations of the fundament. It improves the complexion also, and by its fertilising tendencies promotes the growth of the hair. The cicus or seed from which this oil is made no animal will touch, and from these grape-like seeds wicks are made which burn with a peculiar brilliancy. The light, however, that is produced by the oil is very dim, in consequence of its extreme thickness. The leaves are applied topically with vinegar for erysipelas. Fresh gathered they are used by themselves for diseases of the mamillæ and defluxions. A decoction of them in wine with polenta and saffron is good for inflammations of various kinds. Boiled by themselves and applied to the face for three successive days they improve the complexion."
