* Ebers Papyrus, pl. lxxviii. 1. 22--lxxix. 1. 1: "To relieve a child who is constipated.--An old book. Boil it in oil, and apply half to the stomach, to provoke evacuation." It must not be forgotten that, the writings being on papyrus, the old book in question, once boiled, would have an effect analogous to that of our linseed-meal poultices. If the physician recommended taking an old one, it was for economical reasons merely; the Egyptians of the middle classes would always have in their possession a number of letters, copy-books, and other worthless waste papers, of which they would gladly rid themselves in such a profitable manner.
The medicaments compounded of these incongruous substances were often very complicated. It was thought that the healing power was increased by multiplying the curative elements; each ingredient acted upon a specific region of the body, and after absorption, separated itself from the rest to bring its influence to bear upon that region. The physician made use of all the means which we employ to-day to introduce remedies into the human system, whether pills or potions, poultices, or ointments, draughts or clysters. Not only did he give the prescriptions, but he made them up, thus combining the art of the physician with that of the dispenser. He prescribed the ingredients, pounded them either separately or together, he macerated them in the proper way, boiled them, reduced them by heating, and filtered them through linen. Fat served him as the ordinary vehicle for ointments, and pure water for potions; but he did not despise other liquids, such as wine, beer (fermented or un-fermented), vinegar, milk, olive oil, "ben" oil either crude or refined, even the urine of men and animals: the whole, sweetened with honey, was taken hot, night and morning. The use of more than one of these remedies became worldwide; the Greeks borrowed them from the Egyptians; we have piously accepted them from the Greeks; and our contemporaries still swallow with resignation many of the abominable mixtures invented on the banks of the Nile, long before the building of the Pyramids.
It was Thot who had taught men arithmetic; Thot had revealed to them the mysteries of geometry and mensuration; Thot had constructed instruments and promulgated the laws of music; Thot had instituted the art of drawing, and had codified its unchanging rules. He had been the inventor or patron of all that was useful or beautiful in the Nile valley, and the climax of his beneficence was reached by his invention of the principles of writing, without which humanity would have been liable to forget his teaching, and to lose the advantage of his discoveries. It has been sometimes questioned whether writing, instead of having been a benefit to the Egyptians, did not rather injure them. An old legend relates that when the god unfolded his discovery to King Thamos, whose minister he was, the monarch immediately raised an objection to it.
