ATTENTION has been drawn in the Geological Magazine (for 

 May, 1905, and July, 1906) to the first and second volumes of 

 the English edition of Suess's great work. The present volume 

 constitutes part 4, or vol. iii, part 2, of the original German edition. 

 It is divided into seven chapters, and Professor Sollas, who has 

 continued his labours as editor, has been assisted in the revision of 

 the translator's rendering by Sir Archibald Geikie, Dr.Teall, Professor 

 Edgeworth David, Professor Watts, Mr. E. D. Oldham, Professor T. C. 

 Chamberlin, Professor Lapworth, and Professor Bonney. We give the 

 names in sequence according to the chapters revised by them ; but 

 Professor Sollas remarks in his preface, " The reverence due to a great 

 classic has restrained us in this, as in previous volumes, from taking 

 any liberties with the text, whether by comment or emendation." 



The footnote references have been extended so as to include 

 researches published during the present century, but we miss 

 a reference to the Geological Survey Memoir on " The Geological 

 Structure of the North-West Highlands of Scotland," 1907, which 

 might have been given on p. 387. Britain, however, occupies but 

 little space in the present volume, and only in connection with the 

 Caledonian lines of disturbance. 



An interesting outline of the contents is given in the introductory 

 chapter, where we find remarks on the folding of the oldest rocks and 

 the trend of the systems of folds which form the mountain chains ; on 

 the distinction between longitudinal volcanic lines and independent 

 volcanic lines, and the impossibility of considering folds and volcanoes 

 apart from one another ; and on the need of studying the structure of 

 mountain chains in plan as well as in section. 



In reference to the subjects under discussion, it is remarked that 

 " In the Southern Hemisphere the space covered by the sea is so great, 

 and our knowledge so incomplete, that we can scarcely expect to arrive 

 at any important conclusions. The present investigation is therefore 

 almost exclusively confined to the Northern Hemisphere, and more 

 especially to that region which lies north of the southern boundary of 

 Eurasia and of the Caribbean Sea." The map appended to the volume 

 does not include the entire area. It is a "Diagrammatic Representation 

 of the Vertex of Eurasia," and it takes in the country between Lakes 

 Balkhash and Baikal, the Thian-Shan, and the upper regions of the 

 Hoang-ho. The region around Lake Baikal is described as " the most 

 ancient vertex of the Eurasian folds." 



In the Introduction it is pointed out that " all the Archaean rocks of 

 the earth have suffered folding or an equivalent compression," and 

 that "folded ranges had been already levelled down in times preceding
