So good a judge as Prof. Virchow wrote of this work on its first appearing 

 that since the time of Pritchard and Waitz no such extensive attempt had been 

 made to represent our knowledge of the lower races of mankind, immensely 

 augmented as this has been by the researches of travellers, the exhibition of 

 savages in Europe, and the information opened to the public by the great 

 museums. 



In this volume (Vol. II.) the description of the American-Pacific Group of 

 Races is concluded with an account of the Americans, i, The Cultured Races 

 of America ; 2, The Ancient Civilised Races of America ; and 3, The Arctic 

 Races of the Old World. Book III. treats of the Light Stocks of South and 

 Central Africa ; and Book IV. , The Negro Races.

 Unwin. 1897.) Price 3/6. 



Those who have read Mrs. Brightwen's charming little books, "Wild 

 Nature Won by Kindness" and " More about Wild Nature," will be charmed 

 with the one now before us, in which she tells us about the life-history of 

 the different plants. Here she helps us to enjoy spending hours in a garden, 

 learning to understand the structure of plants, and enabling us, when we 

 see a bud, or a root, or a twig, to know what the history of that object is, how 

 it comes to have the shape it takes, how it developes into its present condition, 

 and what its next form will be. The careful reading of this book will help to 

 turn a country walk from a useless lounge to a lively object-lesson, delightful 

 from beginning to end. There are nearly 100 good illustrations.
