ABSTRACT
That thou mayest know whether-a woman hath conceived a boy or a girl. Find out what day of the moon it is, [reckon up the numerical values of the letters in the name thereof,] and reckon up the numerical values of the letters in the name of the woman, and add to it twenty-eight, and then divide each by two. If the remainder be one, the child is a boy, and if it be two, the child is a girl.
