Trans, for 1683; and that of the discovery of the capillary circulation of the blood in Phil. Trans, for 1790.

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.

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