THE theory of numbers has an appeal to general interest, not shared by other branches of mathematics, in that most of the great unsolved problems of the subject are formulated in terms intelligible to everybody. There must be many people of limited mathematical attainments who have felt attracted to the subject, but whose interest has died away for the want of just such a book as this to stimulate it.
