Abstract
THESE two volumes belong to the Encyclopédie scientifique des Aide-Mémoire, and, like most of the volumes in this series, they contain concise statements of the subjects with which they deal. M. Dumont examines the various systems of horseless traction in use. He begins with steam motors, and then in successive short chapters describes compressed air motors, gas and oil motors, motors driven by carbon dioxide and by ammonia, cable traction, and electric motors. The descriptions are not detailed enough to be entirely satisfactory, nevertheless the volume contains a useful survey of the condition and methods of automobile traction.
