The second part of Mr. Cox's _brochure_ is devoted to a consideration of the spontaneous generation theory, and its relation to the general theory of evolution. Mr. Cox's personal conclusion is, that, to the better part of the scientific authorities, "the spontaneous generation theory is a necessary part of the general theory of evolution, but that no experimental evidence has as yet been produced in support of the belief in the occurrence of abiogenesis, and that therefore the evolution theory hangs upon a link of pure faith." Mr. Cox finds in the gap between lifeless substances and living forms the veritable "Missing Link." Ω. NOUVEAUX APERÇUS SUR LA PHYLOGENIE DE L'HOMME. By _Madame Clémence Royer_. Extracted from the Bulletin de la Société d'Anthropologie for 1890. Madame Royer, in this admirable memoir, taking for a text the fact that an Australian lizard was seen by M. de Vis walking on its hind feet, criticises severely Haeckel's genealogy of man, whose line of descent she declares to be distinct from that of the apes. The first terrestrial ancestors of man and of other anthropomorphous animals issued from pelagic forms of distinct origins, whose evolution had been parallel, but the human ancestors acquired the upright position in a phase of amphibious ichthyophagy, while the ape ancestors adapted themselves directly to an oblique position. This original difference of attitude adapted men from the first to an entirely pedestrian motion, and the apes to a life more or less arboreal, but neither men nor apes have had any terrestrial ancestor adapted to the horizontal position. Ω. LE MONDE COMME VOLONTÉ ET COMME REPRESENTATION. Par _Arthur Schopenhauer_. Traduit en Français par _A. Burdeau_. Tome troisième. Paris: Félix Alcan. M. Burdeau's translation of the chief work of the renowned philosopher of pessimism is the only perfect translation into the French language. It is made with a scrupulous exactness, and its style is said to be as clear as that of Schopenhauer himself, "by which he is distinguished from all other German philosophers and is recognised as a disciple of Voltaire, Rousseau, and Chamfort." The present volume contains important appendices in which Schopenhauer recapitulated and developed various points treated of in the first edition of his work. We may refer particularly to the chapters on Instinct, Genius, Insanity, the Metaphysic of Music, and the Metaphysic of Love. DIE HYPNOSE UND DIE DAMIT VERWANDTEN NORMALEN ZUSTAENDE. Vorlesungen gehalten an der Universität Kopenhagen im Herbste 1889. By _Alfred Lehmann_, Ph. D. Leipsic: O. R. Reisland.
