Wallace, Alfred Russel, English naturalist, born at Usk, in Monmouthshire; was devoted to the study of natural history, in the interest of which he spent four years (1848-52) in the valley of the Amazon, and eight years after (1854-62) in the East India Archipelago, from the latter of which expedition especially he returned with thousands of specimens of natural objects, particularly insects and birds, and during his absence he wrought out a theory in the main coincident with Darwin's natural selection in corroboration thereof; he has since devoted much of his time to the study of spiritualism, and in spite of himself has come to be convinced of its claims to scientific regard; he has written on his travels, “Contributions to the Theory of Natural Selection,” “Miracles and Modern Spiritualism,” &c.; (b. 1823).
