Manchester Science Lectures. Ninth and tenth series. (Manchester, J. Heywood.)—Again

wo have to welcome the appearance in a cheap form of two fresh series of " Science Lectures for the People."

Seventeen lectures, popular in the best sense of the word, having been first delivered in the Hahne Town Hall, Manchester, are here reproduced with illustrations. The lecturers include such masters of their several subjects as Professors Martin Duncan, Huxley, Barrett, and Abel. A dis- course on animal intelligence, by Mr. G. J. Romanes, is the last iu the list, but it is one which will provoke as much attention as the rest, perhaps

bringing up a brood of ferrets, and of the mistakes that the latter made, particularly their attempts at sucking their foster-mother! The other lectures include many subjects belonging to biology and physics, the titles of some of them being,—" Modern Discoveries in Sound ; " "Edison and Some of his Inventions ; " " Flame ; " " Gun- Powder ; " "Our Earliest Ancestors in Britain ; " "Insectivorous Plants ; " and "Harvey's Discovery of the Circulation of the We commend this volume as most suitable, like its predecessors, for general perusal.
