Several carcasses of animals lay scattered about close at hand, partly hidden by the snow- among them two or three skeletons of horses, picked clean by birds of prey; their long heads, at the end of the slender vertebral columns, peering out horribly at them, and their ribs, like the sticks of an open fan stripped of its covering, appearing above the smooth white surface, bearing each one its little load of snow.- "Captain Fracasse", Theophile Gautier.
He ventured on a defence of the Nebular Hypothesis and a criticism of Owen's Vertebral Theory of the Skull; and he was working at the question of the form and symmetry of animals, which he interpreted as " determined by the relations of the parts to incident forces."- "Herbert Spencer", J. Arthur Thomson.
