Horology.- D[erham] (W[illiam]) The Artificial Clock-maker. A Treatise of Watch, and Clock-work..., first edition, errata slip pasted in at end of Preface, folding woodcut plate of musical notation and chimes, woodcut diagrams, Addenda leaf at end, title with contemporary ink signature on verso (erased), another signature at head of Preface partly erased causing hole with loss of a few letters from first line on verso, rather soiled and stained, plate torn along fold, contemporary mottled calf, rubbed, upper joint split, [Baillie p.123; Clockmakers' 255; Tardy p.74; Wing D1099], 8vo in 4s, for James Knapton, 1696. ⁂ Rare; the first comprehensive and scientific treatment of the art of horology, with far greater detail on clock & watch movement and construction than given by John Smith in his Horological Dialogues of 1675. Derham also produced the earliest, reasonably accurate estimate of the speed of sound. In his preface to the present work he admits to having had help "in the History of the Modern Inventions" from Hooke and Tompion.
