According to Athenæus, a good physician ought to be a good cook. (Deipnos. vii.) Upon the authority of Daphnus, the Ephesian physician, he decides that night is the most proper time for taking the supper or principal meal, because, says he, the moon promotes putrescency, and digestion is a species of putrefaction. (vii, 2.) The processes which food undergoes in the body from its first introduction to its complete assimilation are stated in a very scientific manner by Macrobius. In the first place, he says, it is dissolved in the stomach, as much of it at least as is digestible, and that which is not soluble passes down to the intestine, while the chyme, or portion which has been dissolved, passes to the liver, there to undergo the second process of digestion, namely, sanguification, or conversion into blood. It then passes into the arteries or veins, where it undergoes its third species of digestion, namely, purification, by having its recrementitious particles sent off in the form of bile and urine. It is then conveyed to the different parts of the body where the fourth process of digestion is accomplished, namely, assimilation, by which it is converted into the different substances of which the body is composed. (Saturnal. vii, 4.) SECT. LXXIV.—ON POT-HERBS. The lettuce is manifestly refrigerant and moistening; it is therefore soporific, and, compared with other pot-herbs, nutritious, forming blood of a very good quality. The endive is refrigerant and moistening, but less so than the lettuce. The mallows cool but not obviously: they rather moisten and thereby loosen the belly; and this they do by means of the viscid juice which they contain. The beet is detergent, and thereby softens the belly; but when eaten in great quantity it occasions pain of the stomach: it removes obstructions of the liver and spleen. The cabbage, when twice boiled before it is eaten, binds the belly, but when only once boiled for a short time, it rather loosens, if eaten with oil, sauce, or salts; as its juice, still more than the dried lentil, is of a purgative quality; and in particular the sea-cabbage is laxative of the belly, being manifestly saltish and bitter. The sea-purslane tree, possessing stronger saline qualities, loosens the belly, and agrees better with the stomach than the cabbage, from having a moderate astringency; it is also fitted for forming milk and semen. The blite and orache (_atriplex hortensis_) and such like are succulent and laxative, but not nutritious. All the thorny tribe, such as the cardoons, the atractylis, and such like are stomachic, except the _cinara_, for, being hard, it forms bad chyme; and, therefore, it is best to take it boiled with oil, fish-sauce, and coriander. The parsley, the horse-parsley (_smyrnium olusatrum_), the water parsnip, and the allsander, are diuretic; but the allsander is aromatic, and more acrid, diuretic, and emmenagogue, whereas the parsley and horse-parsley are sweeter, and,
