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.
