The Effects of Cross and Self Fertilization - DARWIN, Charles - 1876. 
London: John Murray,, 1876. Octavo. Original green cloth, covers blocked with a blind panel, spine lettered and decorated in gilt. Errata slip inserted at p. 1; diagram at p. 53; 109 letterpress tables. Spine slightly darkened, a couple of black marks to front cover, very minor wear to spine ends and lower tips, hinges cracked but holding. A very good copy. First edition. Darwin's research on fertilisation in plants was an offshoot of his work on evolution and natural selection. To demonstrate that genetic variation gave organisms an advantage in the struggle for survival, he performed experiments demonstrating that self-fertilisation weakened plants in comparison with those that had been cross-fertilised. Darwin considered this volume to be a compliment to his 1862 book, Fertilisation of Orchids, though this one was more technical and the initial print run was low, with only 1,500 copies selling in the first year.
