set it up as a reasonable working hypothesis.  Prof.  A. R. Wallace claims for Darwin “that he is the Newton of natural history, and has ... by his discovery of the law of natural selection and his demonstration of the great principles of the preservation of useful variations in the struggle for life, not only thrown a flood of light on the process of development of the whole organic world, but also established a firm foundation for the future study of nature.”  He was buried in Westminster Abbey (1809-1882).

DARWIN, ERASMUS, physician and natural philosopher, born in Nottinghamshire; studied at Cambridge and Edinburgh; practised medicine in Lichfield, and finally settled in Derby; occupied his mind with the study of fanciful analogies in the different spheres of nature, and committed his views, often not without genuine poetic sentiment and melody of expression, to verse, while in the views themselves there have been recognised occasional glimpses of true insight, and at times a foreshadow of the doctrine developed on strict scientific lines by his illustrious grandson.  His chief poetic works were the “Botanic Garden” and the “Zoonomia; or, The Laws of Organic Life,” deemed, in the philosophy of them, not unworthy of criticism by such sane thinkers as Paley and Dugald Stewart (1731-1802).

DARWINIAN THEORY, the theory established by Darwin that the several species of plants and animals now in existence were not created in their present form, but have been evolved by natural law of descent, with modifications of structure, from cruder forms.  See DARWIN, C. R.
