Now the Odynerus, the Anthidium, the Eucera, the Ammophila, and all the hymenoptera which Fabre has observed sleeping at the fall of night, "suspended in space solely by the strength of their mandibles, their bodies tense, their limbs retracted, without exhaustion or collapse"; and the larva of the Empusa, "which for some ten months hang

Above all we need an ardent and interested sympathy, for "we penetrate farther into the secret of things by the heart than by the reason," as Toussenel has said; and "it is only by intuition that we can know what life truly is," adds Bergson profoundly. (7/13.) Now Fabre loves these little peoples and knows how to make us love them. How tenderly he speaks of them; with what solicitude he observes them; with what love he follows the progress of their nurslings; the young grubs wriggling in his test-tubes, with doddering heads, are happy; and he himself is happy to see them "well-fed and shining with health." He pi

For example, to establish the curious relations which exist between the wasps and the Volucellae, what long and repeated experiments were needful!
