About The Cover

Cover pages from three French popular works of (from left) 1903, 1860, and 1893. The illustrations are from La Science pour tous (reviewed on page 976), an account of French efforts to bring science to a popular audience in the period 1850 to 1914. Our expanded book review section also includes reviews on topics ranging from Darwin's illnesses to cold fusion, Halley's comet to urban archeology, and macromolecular thermodynamics to endangered ecosystems.
