REGISTER OF WRITERS REFERRED TO IN THE TEXT OF THE ORIGIN
Works by a considerable number of the people referred to are listed in Darwin's reading notebooks which he kept during the years he was preparing the Origin. See The Correspondence of Charles Darwin, eds. Frederick Burkhardt and Sydney Smith, 4 ( Cambridge, 1988), pp. 434-573. Some of the people to whose work Darwin refers in the Origin later took strong positions for or against his theories; where known, this is indicated below.
JEAN LOUIS AGASSIZ ( 1807-73). Swiss zoologist and geologist, later Professor at Harvard; he became one of Darwin's inveterate critics, continuing to hold a polygenist view (that races were separate creations) and that creation was divided by an ice-age: see "A Period in the History of Our Planet", Edinburgh New Philosophical Journal ( 1843) and An Essay on Classification ( London, 1859).
JOHN JAMES AUDUBON ( 1785-1851). American ornithologist and natural history artist; his observations are cited by Darwin both in The Voyage of the Beagle and the Origin. See his Ornithological Biography, or an Account of the Habits of the Birds of the United States of America, and Interspersed with Delineations of American Scenery and Manners ( 5 vols.; Edinburgh, 1831-49).
CHARLES C. BABINGTON ( 1808-94). Botanist, taxonomist, and beetle collector; worked in the Channel Islands; Darwin's contemporary at Cambridge, later Professor of Botany there.
ROBERT BAKEWELL ( 1725-95). By experimental breeding produced new and more profitable strains of sheep and cattle; his endeavours are a striking example of the power of 'artificial selection'. The attempt by Buckley and Burgess to keep Bakewell's strain pure and consistent over fifty years
