Beviews — Loivrys Charts of Natural History. 465 



lated, however, to afford education of a still higher character, and 

 to pupils of all ages : they are, therefore, not only fitted for the 

 school and class-room, but every lecturer on Natural History should 

 possess a copy of each, and no museum can be complete without 

 these admirable and instructive guide-maps. 



In recent Natural History, Mr. LoAvry's task is drawing to com- 

 pletion, the last of his charts — that to contain the Mammalia — being 

 announced to appear this year. 



In Paleontology a good deal more it is hoped will be done ; but 

 we wish especially to allude to his latest labour. 



The Chart of British Fossils is, as it were, a general outline of 

 British organic remains, arranged according to the strata. 



The Chart of Fossil Crustacea, by Messrs. J. W. Salter and H. 

 Woodward, gives a conspectus of a single class, arranged not only in 

 stratigraphical series, but in zoological order. It contains nearly 

 600 figures, and is, moreover, accompanied by a short descriptive 

 catalogue.^ 



That of Characteristic British Tertiary Fossils is an elaborated view 

 of the topmost or newest section of the Chart of British Fossils, and 

 holds the same relation to it which a map of Europe does to a m.ap 

 of the World. It contains upwards of 800 figures of characteristic 

 shells and other organisms found in the series of formations of 

 Cainozoic or Tertiary age, which have been engraved by Mr. Lowry 

 expressly for this work, and selected by him with great care, assisted 

 by Messrs. Kobt. Etheridge, Searles V. Wood, Fred. E. Edwards, and 

 other geologists of eminence, and contains a mass of information 

 never before collected in so compact a form for reference. Every 

 specimen is not only named, but has its natural size indicated against 

 it, if it be enlarged or reduced. Those Crag species which occur in 

 more than one bed are also marked by the initial letter of the beds 

 in which they have been found, thus giving the range of each. 

 Very much interest is no'w taken in Tertiary geology, because we 

 see that the fauna and flora of our present earth is really only a 

 modified remnant of the previous age, and that, both on land and in 

 the sea, there exist numerous descendants of all the lower forms of 

 life which are found fossil in these later formations ; but instead of 

 their all now living on our shores, some have gone further south, 

 whilst others have retreated in a more northerly direction according 

 to their arctic or tropical tendencies, thus revealing to us a wonderful 

 history of alternations of climate, further confirmed by the presence 

 of scratched boulders and Glacial Drift, teUing of glaciers and ice- 

 bergs over all the land, but which are now happily melted. 



We strongly recommend these charts to all lovers of Natural 

 History, but would especially call the attention of geologists to this 

 new and interesting Chart of Chakactebistic British Tertiary 

 Fossils.
