‎ Première édition. C'est le premier ouvrage d'un des pères de la biologie moderne. Il y met en évidence la parthogénèse chez les pucerons. Ses expériences, rigoureusement menées, sont ici minutieusement décrites: Car "nous devons nous défier de ce qu'indique le raisonnement & consulter l'expérience autant que nous le pouvons." La seconde partie est consacrée à ses "Observations sur quelques espèces de vers d'eau douce qui coupés par morceaux, deviennent autant d'animaux complets." Très bel exemplaire. /// 2 volumes in-12 de (4), XXXII, 228 pp., un tableau et 4 planches h.-t. / (12), 232 pp., un tableau et 4 planches h.-t. Veau marbré, dos à nerfs orné, tranches rouges. (Reliure de l'époque.) //// First edition. It is the first work of one of the fathers of modern biology. He demonstrated the existence of parthenogenesis in the plant louses. Its experiments, rigorously undertaken, are thoroughly described here: For " we must defy ourselves of what the reasoning indicates & to consult the experiment as far as we can it. " Well before Claude Bernard, Bonnet attributed a preponderant role in scientific research to the "art of observing". The second part is devoted to its " Observations on some species of fresh water worms which crossed per pieces, become complete animals as many." "This pioneering work on experimental entomology incorporates Bonnets most important discoveryparthenogenetic reproductionbased on his study of aphids. Bonnet used the result of this and other discoveries as a basis for speculation about life on earth. This work presents in tabular form his version of the great chain of being. Bonnets concept of the essential continuity of life, a consequence of his discovery and preformationist interpretation of parthenogenesis, was a major force in the shaping of later evolutionary opinion."
