whole of wliich have been drawn Ijy his own hand, and in order that the 

 learner should not find it too technical, the common names of plants have been 

 used as far as practicable, and tlie most familiar plants have l^een selected to 

 illustrate structure. A very copious glossary has also been added.

Mycetozoa, and Bacteria. By A. de Bary, Professor in the University of

 illustrations. Royal Svo, pp. xviii. — 425. (Oxford : Clarendon Press. 1887.) 

 Half morocco, price 22s. 6d. 



In this fine work the author tells us that he has endeavoured to make his 

 remarks intelligible even to those who are only beginning the study of the 

 Fungi, but has assumed that his readers are masters of such a general know- 

 ledge of botanical science as is to be obtained by a course of study in a uni- 

 versity or by the use of good text-books. The first portion of the volume 

 treats of the General Morphology, the Course of Development, and The Mode 

 of Life of Fungi ; the second part. The Morphology and Course of Develop- 

 ment and Mode of Life of the Mycetozoa ; the third, Morphology and Mode 

 of Life of the Bacteria or Schizomycetes. Eleven pages at the end of the 

 book are occupied by an Explanation of Terms. There is also an exhaustive 

 index. The illustrations throughout are exceedingly clear and good.

 pared. 



Zoological Photographs, being Short and Interesting Chap- 

 ters on Natural History. By Joseph Hassell, A.K.C.Lond. Crown Svo, pp. 

 166. (London: Sunday Scliool Union.) 



The subjects in this book are treated in a thoroughly interesting manner, 

 and at the same time the scientific has not been sacrificed to the popular. 

 Modern classification has been kept to throughout, and one or more of tlie 

 leading creatures in each sub-kingdom have been taken as a type of the whole. 

 For the assistance of teachers and the instruction of older scholars, a general 

 view of the sub-kingdom is given at the end of each group. The book con- 

 sists of 15 chapters, commencing with the History of a Sponge as told by 

 itself up to the Story of the Cuttle Fish. The illustrations are numerous and 

 good. ■

This useful work is planned upon the same lines as Hooker and Baker's 

 " Synopsis Filicum," and the two taken in connection cover the whole series 

 of the Vascular Cryptogamia. The synopsis proper occupies the first 150 

 pages, and is followed by a valuable key to the (Orders and Genera, beyond
