Containing his new principles of gunnery, with several subsequent discourses on the same subject, the greatest part never before printed. Vol. II. Containing his discourse on the methods of fluxions, and of prime and ultimate ratios, with other miscellaneous pieces London: J. Nourse, 1761. FIRST EDITION. Two volumes. 8 vo. Contemp. speckled calf. xlvi, (2, contents), 341, (3, pub. ads); (2), 380 pp. Three engraved plates, one folding + text woodcuts. Vol. I joints cracked and one corner bumped, vol. II joint partially cracked; a good to very good set, internally very good. With his 'New principles of gunnery', 1742, Robins became the real founder of the science of gunnery. Therein Robins introduced the ballistic pendulum which he employed to determine the muzzle velocity of bullets. That advance, and others, caused Euler to issue his German translation in 1745. Robins' second volume contains an important work on fluxions which first appeared in 1735. Commenting on the original edition, the Newton/Babson Catalogue has: "In this little book, Robins was the first to give an exceedingly clear explanation of Newton's theories of fluxions." The polemics on the vis viva controversy and other published and unpublished articles complete the set. Biblio. mechanica, pp. 279-280. F. Cajori, 'Hist. concepts, limits and fluxions in Gr.

Edition : First edition, Contemporary speckled Full Calf. Spine in six compartments of five raised bands, with gilt motifs, and gilt title on two and three. , The first edition of this posthumous collection of tracts by Benjamin Robins (1707-1751) includes his significant work on artillery and gunnery as well as more abstract work on fluxions. Robins?s substantial accomplishments in mathematical theory, scientific discovery, technical practice and literary production place him at the forefront of the British Enlightment. As a British artillery officer wrote in 1789, Robins ?was in gunnery what the immortal Newton was in philosophy, the founder of a new system deduced from experiment and nature?

2 volumes, 8vo, pp. xlvi, (ii), 341, (3) adverts, 2 engraved plates (1 folding); (viii), 7?380, 1 engraved plate. Half-titles. Contemporary speckled calf, spines ruled in gilt with red morocco labels. Joints rubbed, heads of spines slightly worn and crack at top of upper joint of vol. 2, but a very good and clean set. With the engraved armorial bookplates of Ramsey Abbey. FIRST EDITION of Robins? collected works, including some published for the first time. The first volume is entirely concerned with gunnery; it includes Robins? description of the ballistic pendulum, invented by him, studies on the pressures in a gun-barrel, rockets for signalling purposes, the resistance of fluid media to high-speed objects, etc. This last aspect applied Newtonian mechanics to artillery, and brought about ?an epoch-making improvement in the accuracy of field guns? (Prof. Niall Ferguson, ?Civilisation: is the West History??). The second volume is mathematical, including his discourse on Newton?s fluxions, of whom Robins was a staunch supporter. The editor James Wilson, in the long appendix, appraised Newton?s Method of Fluxions, and first revealed Newton to be the author of the Account of the Book entitled Commercium Epistolicum, Newton?s fullest account of the development of his own mathematical ideas.
