We have received the first part of an attractive encyclopaedia,

Cassell's Children's Book of Knowledge, which is to be published in about forty-eight fortnightly parts (1s. 3d. net each). The contents are arranged alphabetically ; they are copiously illustrated. The first part deals with a wide selection of A's ranging from Aachen, the Academie Francaise, the Aeroplane, down to Air Plants, and Alaric the Goth. The notes are freshly and entertainingly written. The section devoted to Africa contains some remarkable photographs of wild animals, while several Maps, showing the natural conditions of the continent, are printed in vivid reds and greens and blues and purples and oranges—infinitely more romantio than the pale colours of the ordinary geography book. This alone shows that the compilers have approached their task in the right spirit.
