Animal locomotion or walking, swimming, and flying : with a dissertation on aëronautics
A scientific treatise by anatomist James Bell Pettigrew, published in London in 1873 for naturalists and early aeronautics researchers, analysing how animals walk, swim and fly. The line engravings diagram wings, fins and limbs in motion, with dotted arcs, lettered reference points and arrows tracing stroke paths, useful for motion-study graphics, technical annotation styles and bird and insect wing silhouettes.
