Animal locomotion, or Walking, swimming, and flying, with a dissertation on aëronautics
A scientific treatise on animal locomotion by anatomist James Bell Pettigrew, published in New York by D. Appleton in 1874 for naturalists and early aeronautical experimenters. Wood-engraved figures show birds with wings spread, wingbeat paths traced in dotted lines and arrows, and lettered diagrams of flight geometry, useful as motion notation and labelled anatomical line art.
