D ARWIN revealed himself so largely in his books,

that a vivid picture of much of his life can be extracted from them. Thus it has been found possible to combine much biographical interest with sketches of his most important works. Like other biographers of Darwin, I am much indebted to Mr. Woodall's valuable memoir, contributed to the Transactions of the Shropshire Archæological Society. But original authorities have been consulted throughout, and the first editions of Darwin's books quoted, unless the contrary is explicitly stated. I am greatly obliged to Messrs. F. Darwin and G. J. Romanes for kindly permitting me to quote from Mr. Darwin's letters to Mr. Romanes. I must also express. my thanks to my friends, Mr. Romanes and Prof. D'Arcy W. Thompson, for doing me the great service of looking over the proof-sheets of this book.
