Darwin, Charles Robert, iii, 95, iv, 173. Born 

 at Shrewsbury, England, Feb. 12, 1809; died at

 the "Beagle" expedition, 1831-36, and made 

 many important contributions to zoology and 

 geology. Announced his theory of natural se-

 the same idea independently, in 1858. Published 

 "Origin of Species" in 1859. This revolutionized
