Derham, William THE ARTIFICIAL Clock-maker. A Treatise of Watch, and Clock-work... First edition printed for James Knapton 'at the Crown in St Pauls Church-yard', London 1696, with folding woodcut plate of musical notation and chimes (loss to edge margin), woodcut diagrams and Addenda leaf at end, 8vo in 4s, contemporary tooled calf, (title with ink signature Jacob Mefsing, some soiling and staining). A rare first edition of the first comprehensive and scientific treatment of the art of horology, with far greater detail on clock and 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. See Baillie, G.H.
