Leonardo da Vinci, Artist, Thinker, and Man of Science, by Eugene Muntz, 2 vols., New York, 1892, is perhaps the most complete treatment of all phases of Leonardo's work as a scientist as well as an artist. The older French work, Essai sur les ouvrages physico-mathematiques de Leonard de Vinci, by J. B. Venturi, Paris, 1797, is excellent. In German, H.

Grothe's Leonardo da Vinci als Ingenieur und Philosophy Berlin, 1874, is good.
