Reviews — Prof. Bonneifs Story of Our Planet. 87 



The chapters on economic geology, treating of Lime and Cement, 

 of Artificial Stone and of Building Stone, Ornamental Marble, of 

 Iron Ore, etc., of Agriculture, Soils, and Water Supply will be read 

 with interest by all those who, as landed proprietors, have a stake 

 in the prosperity of the areas embraced in this Memoir. The 

 Chalybeate Springs of Bath, Cheltenham, and the surrounding 

 country are extremely numerous and many of them of great 

 historical antiquity and virtue. 



The fauna of the Lias formation is one of the richest of the 

 British Islands, not only in Flying, Walking, and Swimming Reptiles, 

 but in Fishes and Mollusca; and especially in that remarkable group, 

 the Cephalopoda, by aid of which the various zones of the Lias 

 have long been characterized, the Brachiopoda, Crustacea, Worms, 

 Echinodermata, Corals, and Foraminifera are also well represented, 

 whilst remains of Plants, numerous Insects, Flying Pterodactyls, 

 Dinosaurs, and Crocodiles proclaim the pi-esence of a contiguous 

 continent, the shores of which were washed by the Liassic seas. 



Owing to the inferior quality of the paper on which it is printed, 

 this valuable Memoir is presented to the public under great dis- 

 advantage ; for, notwithstanding the fact that numerous illustrations 

 have been lent to adorn its pages, they are mostly so poorly printed 

 as to fail to express clearly the objects which the artist has drawn. 

 This censure on the printing in no wise detracts the vast amount of 

 arduous scientific labour, the results of years of patient field-work 

 by Mr. Woodward, which this Memoir has involved ; nor must we 

 omit to commend the admirable list of fossils, with their respective 

 horizons, occupying just 50 pages of small print, drawn up by the 

 author with the assistance of his colleagues, Messrs. Sharman and 

 Newton. Unfortunately this catalogue does not include all the 

 Liassic fossils of England and Wales, because the species from 

 Yorkshire are given in the Memoir by Mr. Fox- Strang ways (above 

 referred to), and only those Yorkshire fossils which occur south of 

 the Humber are mentioned in Mr. Woodward's list. 



To obtain a full record of the Liassic fossils of England and Wales, 

 it will be necessaiy, therefore, to combine the catalogues given by 

 Mr. Fox-Strangways with that contained in the present volume. 

 Surely this might have been done by the officers of the Survey' — 

 by mutual agreement — and so the public-at-large, or at least the 

 scientific public, instead of grumbling, would have had reason to 

 laud and magnify the Director-General and his staff for ever ! We 

 shall look with interest for the appearance of volume iv. with the 

 Lower, and of volume v. with the Middle and Upper Oolitic 

 divisions of the Jurassic rocks.
