On the Sabbath one may carry a grasshopper's egg as a charm against
earache, the tooth of a living fox to promote sleep, the tooth of a dead
fox to prevent sleep, and the nail of one crucified (as a remedy) for
inflammation or swelling. For cutaneous disorders he is to repeat Baz
Baziah, Mass Massiah, Cass Cassiah, Sharlaii, and Amarlaii (names of
angels), etc.... As the mules do not increase and multiply, so may the
skin disease not increase and spread upon the body of N., the son of the
woman N., etc.

THE TALMUD, _Shabbath_, fol. 67, col. 1.
