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.
