Principles of Geology: Being an Inquiry how Far the Former Changes of the Earth's Surface are Referable to Causes Now in Operation.
Two works in six volumes. "Principles..." third edition. Four volumes. Small 8vo. Publisher's green moiré cloth backed drab boards, printed paper spine labels, early ownership inscription of an "R. Burdon" to the upper board of three volumes, contemporary small circular ticket of the bookseller "S. Simms" of 12 George Street, Bath to the front pastedown of volume I. Frontispiece and 12 mostly folding plates, including 2 hand coloured views and 2 hand coloured geological maps plus numerous illustrations in the text. "Elements..." second edition. Two volumes. Small 8vo. Publisher's green beaded cloth backed drab boards, printed paper spine labels. Handcoloured frontispiece, 2 handcoloured folding maps and 5 folding plates (1 colour, 4 black and white). Some darkening and wear to the spine labels, superficial split to the lower joint of volume I of the "Principles" though it remains sound, occasional scattered foxing, a very good unsophisticated set. "...Lyell probably accomplished more in the advancement of geological knowledge than any other one man. The world wide influence of his treatises and textbooks definitely established the principles of uniformitarianism" (Mather and Mason p. 263). Donovan, pp. 89-90. The first edition of the "Principles" appeared in three volumes published between 1830 and 1833, with second editions of volumes I and II appearing in 1832. The fourth volume here concludes Lyell's text and is thus the first complete edition. The "Elements" was first published in one volume in 1838 and was continually expanded and revised over the succeeding decades. Lyell intended the work to be a more accessible description of the science than provided by the overarching tenets of the "Principles", seeking to "explain his conception of geology at an introductory level, and thereby propagate it more widely...". He "reviewed the whole stratigraphical record, from the most recent formations back to the most ancient, interpreting it in terms of the 'uniformity' of terrestrial processes through time" (ODNB). Unusual to find both of Lyell's principle works in the original, near matching, bindings.
