Modern cloth, spine label; with the exception of minor browning and the repair of the last 3 leaves, a very good copy. First editions of both the first treatise and the supplement. Bashforth, a British applied mathematician, invented a chronograph to measure the effect of resistance of air on ballistics. He includes numerous tables of mathematical values related to his experiments. After explaining the limitations of experiments on ballistics undertaken by Galileo, Newton, Bernoulli, Euler, Legendre, Lambert, Poisson and others, Bashforth relates how he undertook to construct a chronograph in order to obtain a "satisfactory solution of any question in gunnery." The use of the chronograph in experiments, especially with long shots, is detailed.Bashforth (1819-1912), who studied at Cambridge University and became a professor of mathematics at the Royal Military Academy, Woolwich, received an award from the British government in the amount of 2000 pounds for his invention. He is also known for his work studying liquid drops and surface tension; the Adams–Bashforth method (a numerical integration method) is named after him and John Couch Adams. Bookseller Inventory #
