‎---- PREMIERE EDITION FRANCAISE ---- BEL EXEMPLAIRE ---- "Arnold Lang, (1855/1914), was professor of zoology and comparative anatomy at the University of Zurich and at the Eidgenössische Technische hochschule where he took over the directorship of the zoological collections and founded a zoological institute. His interest in zoology was awkened in Geneva by Karl Vogt. At the latter's suggestion Lang translated Lamarck's philosophie zoologique into german. In later writings he repeatedly discussed Lamarck's theory and questions pertaining to the history of the theory of evlution. His zoological works grew out of his research at Naples under the direction of Dohrn and were devoted to such topics as sessile crustaceans and the comparative anatomy and histology of the nervous system of the platyhelminths... In his popular Lerhbuch der vergleichenden Anatomie der wirbellosen Tiere (dont nous proposons la traduction française), Lang provided a critical account of the results of his own work and of other original papers on the subject. Through his studies on annelid phylogeny, and especially through his derivation of metamerism and his trophocoel theory of the formation of the entire alimentary canal, Lang participated vigorously in the debate over the problem of the origin of the bodily cavities in general. Moreover, his hybridization experiments with species of the genus Helix confirmed Mendel's results...".(DSB VIII p. 3) ---- Des animaux uni-cellulaires - De la cellule considérée comme point de départ du développement des animaux supérieurs et des cellules qui composent le corps de ces animaux - Protozoaires - Zoophytes ou célentérés - Cestodes et trématodes - Platodes - Vers - Arthropodes (branchiata, tracheata) - Mollusques - Echinodermes - Entéropneustes - Cephalodiseus et rhabdopteura**3088/A7AR‎
