L'HOMOGENEITE MORALE. By _G. Fonsegrive_. CONTRIBUTIONS PSYCHO-PHYSIQUES A L'ETUDE ESTHETIQUE (fin). By _G. Sorel_. LA FOLIE DE J. J. ROUSSEAU. By _H. Joly_. LA PERCEPTION DES LONGUEURS ET DES NOMBRES CHEZ QUELQUES PETITS ENFANTS. By _Alfred Binet_. ANALYSES ET COMPTES RENDUS. M. Fonsegrive in _L'Homogénéité morale_ points out the necessity of a proper system of education for developing in the mind of the young a moral homogeneity to replace the heterogeneity which psychologists find in the nature of man. In _Contributions psycho-physiques a l'Etude esthétique_, M. G. Sorel continues his studies on the psychology of æsthetics, and concludes that experimental psychology and especially psycho-physics form the base of practical æsthetics. M. H. Joly in _La Folie de J. J. Rousseau_ points out that the problem of the agreement of genius with insanity, so far as concerns Rousseau, is reduced to small dimensions. _La Perception des Longueurs et des Nombres ches quelques petits Enfants_ by M. Alfred Binet, describes certain original experiments which indicate that young children have an accurate perception of differences in length, but that their perception of number is very limited.

In _Les Origines de la Technologie_ M. Espinas aims at giving a history of philosophy in action. The present paper is devoted to physico-theological technology, and concludes with the observation that it was undoubtedly a progress to conceive the technical arts as a whole, as a divine gift in like manner as the fruits of the earth and the beneficent phenomena of _nature_, since this conception by opposition gave rise to the idea of _art_, that is of human initiative acting differently according to diversity of circumstances. In _L'Inhibition dans les Phénomènes de Conscience_ M. Alfred Binet explains certain phenomena by showing that under various circumstances certain images and sensations cannot coexist with others in the same field of consciousness; the presence of one excludes that of another. Antagonism and exclusion are the two simple facts which explain the phenomena in question.
