[Vol. Ill in the Press. 



Revue Scientifique. Nous ne pouvons entrer dans le detail ; mais il est 

 evident que M. Seward, praticien distingue lui-meme, est tres au courant 

 des travaux des autres, il les cite et utilise abondamment ; et ceci est fait 

 pour inspirer confiance. Au total, son oeuvre est appuyee sur des bases 

 solides, et elle restera sans doute longtemps le breviaire, le manuel de ceux 

 qui veulent, non pas seulement s'initier a la paleobotanique, mais retrouver 

 les renseignements qui sont epars dans des centaines de monographies qu'on 

 a souvent peine a se procurer. Le livre de M. Seward fait partie des 

 Cambridge Natural Science Manuals, et il est digne de cette collection, qui 

 est elle-meme digne du foyer scientifique universellement repute, ou il a vu 

 le jour.

Pall Atall Gazette. Precisely the sort of book which, if it came into a 

 thoughtful boy's hands, would turn him from a smatlerer into a student.... 

 One of the most instructive and attractive books that could be put into the

Nature. The clear and simple way in which the author treats the 

 subject is sure to inspire many with interest and enthusiasm for the 



study of forest botany The work will be found indispensable to those 



students who wish to make an expert study of forest botany. At the same 

 time it is expressed in language so clear and devoid of technicalities that 

 the amateur who wishes to know something about our trees and shrubs will 

 find this one of the most useful guides to which he can turn The work is 

 a many sided one, acting not only as a guide to the naturalist in the field, 

 but also as a laboratory handbook, where the use of the lens and 

 microscope may be employed to amplify the study of objects already 

 observed in their natural habitats. Botanists generally, and especially 

 forest botanists, will welcome the appearance of this book as supplying 

 a decided want, and filling a distinct gap in our literature of forest 

 botany.

Field. The work is essentially suited to the requirements of those 

 desirous of studying the grasses commonly grown in this country, and 

 it can fairly be said that it furnishes an amount of information seldom 

 obtained in more pretentious volumes.
