Choice and Chance. By the Rev. William Allen Whitworth. (Bell'

and Daldy.)--An amusing collection of arithmetical puzzles, as well as an instructive manual on the subject of chance and selection. In how many ways can a set of chess-men be placed on a chess-board ? How many changes can be rung upon eight belle ? If two letters are selected at random out of the alphabet, what is the chance that both are vowels ?

These are the questions which Mr. Whitworth enables us to answer.
