Baden Powell, an English author, born in London in 1796, died there, June 11, 1860. He graduated at Oxford in 1817, and from 1827 till his death was Savilian professor of geometry in that university. He was in holy orders, but held no living.' His writings are either strictly scientific, or treat of the connection between science and theology. Among the former are a "History of Natural Philosophy" (1834); "A General and Elementary View of the Undulatory Theory of Light" (1841); and a large number of papers in the transactions of various scientific societies, of which the most remarkable were " Reports on Luminous Meteors," " On the Repulsive Power of Heat," " On the Dispersion of Light," "On Elliptic Polarization of Light," and " On Irradiation." Of the second class are " The Connection of Natural and Divine Truth, or the Study of the Inductive Philosophy considered as subservient to Theology " (London, 1838); " Essays on the Spirit of the Inductive Philosophy, the Unity of Worlds, and the Philosophy of Creation" (185.5; 2d ed., 1856); " The Order of Nature considered with reference to the Claims of Revelation" (1859); and " On the Study of the Evidences of "Christianity," in " Essays and Reviews " (1860). The purpose of the works of the latter class was to maintain that the rejection of ideas generally prevalent upon theological subjects, which in the progress of modern science have been called in question, or at least modified, is in no way a hindrance to a sincere belief in the cardinal truths of religion.
