Groom, P., Trees and their Life Historie s. Illustrated 

 trom Photoe:raphs by Henry Irving. (Cassel & Co., Lon- 

 don, 1907. 407" pp. and 517 figs. 4^ Price £ 1.5.0.) 



Unlike many of the large illustrated works prepared for the 

 tree- and garden-lover and other dilettanti. this book makes a direct 

 appeal to the Botanist. The subject-matter consists of the native and 

 principal cultivated trees of the British Isles and includes 21 Gym- 

 nosperms and 49 Dicotyledons. Following on a general introduction, 

 the different trees are taken seriatim and their structural biological 

 characters adequately described in language studiously free from 

 technicalities. The great feature of the book is the wealth of beauti- 

 ful Photographie illustrations from negatives by Mr. H. Irving. 

 These include, in almost every case, "füll page illustrations of the 

 same tree in its summer and winter aspects. In addition, the bark, 

 buds, foliage, flowers and fruits are represented on an adequate scale, 

 The result of the collaboration is an attractive book which will be 

 decidedly useful to Botanists. F. W. Oliver.
