Eenews—Prof. Blake's Annals ofrSxitish Geology. 89 



Part 3 is devoted to the consideration of changes from within ; 

 commencing with movements of the crust of the earth, illustrated by 

 the well known example of the Columns of the Temple of Serapis 

 and the terraces on the Coast of Norway ; and by faults and flexures 

 of the strata; by volcanic action and its effects, on earthquakes, 

 and the internal changes produced upon rock-masses withm tlie 



crust itself. , , , ^c 



Part 4: deals with the earth's story in past ages, and treats ot 

 meteors and the earth's beginning; of the eras and subdivisions in 

 geological history, and the processes of reasoning by which they have 

 come to be recognized; and so we pass from the Archi^an era, to 

 "the building of the British Isles," of Europe, and other continents ; 

 and, following the author, discuss the earth's life-history. ^ 



Part 5 embraces some theoretical questions, such as the ' Age ot 

 the Earth :" " the permanence of ocean-basins and land-areas^; on 

 " climatal changes," and " the distribution and descent of life. 



This work is essentially, what its author intended it should be, 

 a pleasant readable book. Most of its facts are the common property 

 of many other such volumes on Physical Geography and Geo ogy, 

 such as Elisee Reclus' "La Terre," with a little more geology added, 

 after the manner of " Lyell's Principles." The smallest possible 

 space is given to the so-called Life-History of our globe, a subject 

 which appears to us to be worthy to hold a place of far greater im- 

 portance in the History of our Planet. If we except the figures ot 

 some of the fossils given, the illustrations are, as a rule, ot a Uigli 

 class and will render the book attractive to the general reader, tor 

 whom it is intended. , , 



We think this is a volume which will have many readers, both 



amongst young and old. 



V.-Annals op British Geology, 1892. A Digest of the Books 

 AND Papers Published during the Year-with Occasional 

 Notes. By J. F. Blake, M.A., F.G.S. 8vo. pp. 310, with 100 

 Illustrations. (London : Dulau & Co. 1893.) 



PKOFESSOR BLAKE is to be greatly congratulated on the 

 third annual appearance of this most usetul work. Whilst 

 the volume is arranged almost precisely on the same lines as last year 

 (vide Geological Magazine, 1893, p. 134), certain changes have been 

 introduced. The critical notes are no longer dispersed amongst^ tlie 

 text, but wisely gathered together in the form of an Introductory 

 Eeview, " which," says the author in his preface, " can scarcely be 

 obiected to if we admit the principle that ' thou shalt not muzzle the 

 ox that treadeth out the corn,'" especially, we might add, it he 

 treadeth not on the corn— of another. .■,-,■ j • f 



The illustrations are now, as far as possible, of full size and inter- 

 spersed in the body of the text. All new British species, save those 

 in the Pala^ontographical Society's volume, are figured, with some 

 few others of special interest. i t i i • 



We are still of opinion that the "Foreign Geology (published in
