Amusements in Mathematics 

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In-issuing this new volume Of my Mathematical Puzzles, Of which some have appeared in the periodical press and others are given here for the first time, I must acknowledge the encouragement that I have received from many unknown correspondents, at home and abroad, who have expressed a desire to have the problems in a collected form, with some Of the solutions given at greater length than is possible in magazines and newspapers. Though I have included a few Old puzzles that have interested the world for generations, where I felt that there was something new to be said about them, the problems are in the main original. It is true that some Of these have become widely known through the press, and it is possible that the reader may be glad to know their source. On the question Of Mathematical Puzzles in general there is, perhaps.
