‎---- BEL EXEMPLAIRE ---- Cinquième édition REVUE ET AUGMENTEE DE PLUSIEURS CHAPITRES NOUVEAUX ---- "After 1868, Marey turned to what was then a more novel area for the application of recording devices, the study of human and animal locomotion. Using traces of the motions of bird and insect wings, Marey showed that changes in the form of the wing modify its air-resistance properties ; rather than contracting the wing flexor and extensor muscles, this surface change accounts for much of the upward and forward motion of the flying animal. By this means Marey determined the mechanical requirements for the physiological apparatus of flight...". (DSB IX pp. 101/102)**6678/D4-6679/CART.8-3519/CART.9‎
