Nature. It is not necessary to recommend the perusal of the book to 
all interested in the subject since it is indispensable to them, and we will 
merely conclude by congratulating the Cambridge University Press on 
having added to their admirable series of Natural Science Manuals an 
eminently successful work on so important and difficult a theme, and the 
author on having written a treatise cleverly conceived, industriously and 
ably worked out, and on the whole, well written.

Revue Scientifique. N ous 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 br6viaire, 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 sou vent 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. 
Guardian. We have already alluded to the spirit of caution which 
characterises the book, and we may add that it promises to be most helpful 
to the botanist who would extend his researches into the past. 
Natural Science. A most successful treatment of a difficult subject. 
All of importance is brought forward and impartially discussed.... Such a 
book has long been a desideratum. Mr Seward’s style is clear and concise, 
and the many pitfalls into which beginners are apt to stumble are clearly 
pointed out. 
American Naturalist. Both the botanist and geologist will find 
Mr Seward’s work of the greatest value — quite indispensable, indeed, in 
a study of the fossil flora of the earth. 
Science. The reader must go to its well-laden pages if he is to obtain 
any adequate idea of the wealth of information that it contains.
