Hardcover. Zustand: Fine. 1st Edition. A fine copy of the first edition of Playfair's "well-known masterpiece of geological literature" (Challinor, p.70). "Playfair's principal mathematical work was his Elements of Geometry, 8vo, Edinburgh, 1795 . but the work which will always be most prominently associated with his name is the Illustrations of the Huttonian Theory of the Earth, 8vo, Edinburgh, 1802, on which he spent five years. This work is a model of purity of diction, simplicity of style, and clearness of explanation. It not only gave popularity to Hutton's theory, but helped to create the modern science of geology" (DNB). Playfair distilled Hutton's theory into three sections taking up the first 140pp. of the present work. Dean (p.103-4) believes that this was derived from two papers delivered to the Royal Society of Edinburgh in 1799. The remainder of the book, some 388pp., is entitled "Notes and additions". From these, Dean (pp.109-114) analyses 26 points by which Playfair directly counters Richard Kirwan's arguments. Moreover, Playfair adds his own modifications to Hutton's theory in this section (cf. Dean pp.115-6). This is important, since it was in Playfair's form that Hutton's theory was mostly digested. Indeed, Gould has suggested Hutton's theory "required Playfair's recasting to gain acceptability" (p.63). For instance, one of Playfair's major changes was to accommodate the idea of extinction, and with it a unique prehistoric past. This latter was bound up with Playfair's insistence that incessant processes, rather than Huttonian cycles, are at work. In other words, Hutton's famous line "The result, therefore, of this physical inquiry is, that we find no vestige of a beginning, - no prospect of an end" no longer holds true. Hutton argued in both his 1788 paper (p.209) and 1795 book (pp.175-6) that: "we have but to examine the strata of our earth, in which we find the remains of animals. In this examination, we not only discover every genus of animal which at present exists in the sea, but probably every species, and perhaps some species with at which at present we are not acquainted . Therefore the system of animal life, which had been maintained in the ancient sea, had not been different from that which now subsists". In other words, the cyclical nature of the destruction and rebuilding of continents in his physical system also extends into the animal kingdom. Yet this is not the picture of Hutton's theory that been projected over the last 200 years, mainly because Playfair modified this view in Note XXII (p.458 ff.). Rudwick makes the point that Playfair offered a "bowdlerized version that reduced [Hutton's theory] to a purely mechanical system of physical processes interacting in dynamic equilibrium. This was closely analogous to the dynamic steady state attributed to the Newtonian cosmos" (pp.465-466). Octavo (211 x 132mm). Pp. xx (title, advertisement, contents), 528.

Wrappers. Zustand: Fine. Original article disbound from Volume VII of Transactions of The Royal Society of Edinburgh (not a reprint, facsimile reproduction, or photocopy). Roman numerals preceding title refer to order of sequence as published in the Transactions. Demy 4to (273 x 210mm): 269-278pp, complete with three full-page plates. Recently bound by Fitterer in stiff marbled wrappers. An excellent wide-margined example, tightly bound and clean throughout. Playfair's paper is drawn from a series of letters written by Captain Basil Hall, a British naval officer and the second son of geologist James Hall, after a visit to the Cape of Good Hope and an excursion to Table Mountain in July, 1814. The letters describe the granitic intrusions within the sedimentary sandstone structures that Hall saw in the Platteklip Gorge near Table Mountain. Playfair provides a general description of Table Mountain, which (is now known) was once was part of the ocean bed off the coast of South Africa. Forces from an underground volcano sent magma rushing to the surface, lifting sand and mud from the ocean bed to form the mountain. Playfair is best known for his book Illustrations of the Huttonian Theory of the Earth (1802), which summarized the work of James Hutton and his Theory of the Earth. It was through Playfair's efforts that Hutton's principle of uniformitarianism, later taken up by Charles Lyell, first reached a wide audience. N. B.

Roman numerals preceding title refer to order of sequence as published in the Transactions. Demy 4to (273 x 210mm): 303-375pp, complete with five folding plates and folding map showing Glen Tilt. Recently bound by Fitterer in stiff marbled wrappers. An excellent wide-margined example, tightly bound and clean throughout. The river Tilt is a principal branch of the Tay, which rises on the borders of Aberdeenshire and runs towards the southwest, through the northeastern part of the county of Perth. A portion of the valley along its course, for about ten miles above Blair of Atholl, is called Glen Tilt, which Seymour and Playfair visited to study the geology of the rugged, mountainous terrain. In 1785, Hutton had examined outcrops in Glen Tilt, noting "contact relationships between Precambrian metasedimentary rocks and Paleozoic granite bodies, although he had no knowledge of their true ages." These breccias "were very influential, because they sparked a long, and at times acrimonious, debate about the origins of igneous rocks and especially granite."
