Récréations mathématiques at problèmes des temps ancien et modernes. 2. éd. française traduite d'après la 4. éd., anglaise et enrichie par J. Fitz-Patrick
A French translation of W. W. Rouse Ball's mathematical recreations and problems, published in Paris in 1907 by J. Fitz-Patrick for general readers of puzzles and maths. The page shows typeset algebra: fractions, a substitution x − y = z, and a quadratic equation, set in a plain serif face on yellowed paper. A designer might take from it the dense, unillustrated look of early twentieth-century mathematical typesetting, useful for textured backgrounds or scientific layouts.
