 much valued by the Romans, who attached pieces of it by ribbons to their children's necks, in the belief that it would protect them against the designs of sorcerers; and Paracelsus adopted the same view, recommending necklaces of coral to be worn as a preventive of epilepsy, "but such impostures," says Quincy (1724), "are now deservedly laughed out of the world." Some old writers insisted that coral worn on the person changed colour, becoming dull and pale when the wearer's health failed.

In the seventeenth and eighteenth centuries coral and pearls were considerably used in medicine in the form of magisteries, tinctures, syrups, and arcana. Lemery says coral was given to infants in their mothers' milk as soon as they were born (he does not explain how) to prevent epilepsy, and he names a multitude of other disorders for which it was good. Boyle, too, in his "Collection of Remedies," recommends it in drachm doses to "sweeten the blood and cure acidity." The largest and reddest obtainable was to be chosen.

Pearls were used in medicine until the eighteenth century, when it began to be suspected that chalk had the same effect. The tiniest pearls, known as pearl seeds, ground to a fine powder, were prescribed as an absorbent, antacid, and cordial. This powder was also used, says Pomet, "by ladies of quality to give a lustre and beauty to the face." It was superseded before long by Lemery's magistery of bismuth, which, however, retained the name of pearl white. Pomet further states that a magistery of pearl was made (apparently by quacks) by combining the ground pearl with acids; an arcanum, spirits, flowers, and tinctures were also prepared and credited with marvellous virtues, "to pick fools' pockets."
