In this, as in many other documents, the testimony required is very remarkable, sixteen witnesses being thought necessary for the sale of a moiety of the sums collected on account of a few tombs, and for services performed to the dead, the total value of which was only 400 pieces of brass; and the name of each person is introduced, in the true Oriental style, with that of his father. Nor is it unreasonable to suppose that the same precautions and minute formulas were observed in similar transactions during the reigns of the Pharaonic kings, however great may have been the change introduced by the Ptolemies and Romans into the laws and local government of Egypt. The Egyptians paid great attention to health, and "so wisely," says Herodotus, "was medicine managed by them, that no doctor was permitted to practice any but his own peculiar branch. Some were oculists, who only studied diseases of the eye; others attended solely to complaints of the head; others to those of the teeth; some again confined themselves to complaints of the intestines; and others to secret and internal maladies; accoucheurs being usually, if not always, women." And it is a singular fact, that their dentists adopted a method, not very long practiced in Europe, of stopping teeth with gold, proofs of which have been obtained from some mummies of Thebes. They received certain salaries from the public treasury; and after they had studied those precepts which had been laid down from the experience of their predecessors, they were permitted to practice; and, in order to prevent dangerous experiments being made upon patients, they might be punished if their treatment was contrary to the established system; and the death of a person entrusted to their care, under such circumstances, was adjudged to them as a capital offence. If, however, every remedy had been administered according to the sanitary law, they were absolved from blame; and if the patient was not better, the physician was allowed to alter the treatment after the third day, or even before, if he took upon himself the responsibility. Though paid by Government as a body, it was not illegal to receive fees for their advice and attendance; and demands could be made in every instance except on a foreign journey, and on military service; when patients were visited free of expense. The principal mode adopted by the Egyptians for preventing illness was attention to regimen and diet; "being persuaded that the majority of diseases proceed from indigestion and excess of eating;" and they had frequent recourse to abstinence, emetics, slight doses of medicine, and other simple means of relieving the system, which some persons were in the habit of repeating every two or three days.
