When a Chinese is put in the witness-box, he says: If I do not speak the truth may my soul be cracked and broken like this saucer. So saying, he dashes the saucer on the ground. The Roman Catholic imprecation, known as Bell, Book, and Candle (q.v.), and the Jewish marriage custom of breaking a wine-glass, are of a similar character.
