Originally published in 1892. A fascinating book containing an account of certain Mathematical Recreations followed by some Essays on subjects most of which are directly concerned with historical mathematical problems. The illustrated contents include: Arithmetical Recreations - Geometrical Recreations - Mechanical Recreations - Chess Board Recreations - Magic Squares - Unicursal Problems - Kirkman's School Girls Problem - The Mathematical Tripos - The Parallel Postulate - Insolubility of The Algebraic Quintic - Mersenne's Numbers - String Figures - Astrology - Cryptographs and Ciphers - Hyper Space - Time and Its Measurement - Matter and Ether Theories. Etc. Many of the earliest science books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive.
