A text-book of physics
A college physics textbook edited by A. Wilmer Duff with Guthe, Hallock, and Lewis, published in Philadelphia by P. Blakiston's Son & Co. in 1908 for undergraduate students. The 182 figures are line-drawn diagrams: ray paths and wavefront interference patterns, labelled force and angle constructions, field lines around a magnet, and sectioned apparatus, useful as spare geometric linework and lettered annotation.
