Dictionary of Statistics, by Michael G. Mulhall (Roatledge and Sons),
is a book the usefulness and interest of which are sufficiently declared by its title. Mr. Mnlhall's previous works have proved his competence to deal with the subject, and we need do little more than record the appearance of this very complete book of reference. Any one who should carry it about in his pocket would prove a most dangerous antagonist in social and political discussions. The late Dr. Irons bad a way of thus producing printed authority for any statement which one was rash enough to controvert, and he was treated with corresponding respect. If Mr. Mulhall would print a more " pocketable " edition, though indeed this volume is not bulky, he would be furnishing controversialists with a most formidable weapon.
