LAST year the first instalment of the new edition of " Phillips's 

 Manual of Geology," by Prof. Seeley, was reviewed in the 

 Geol. Mag. We have now to welcome the companion volume from 

 the pen of Mr. Eobert Etheridge, for many years Palaeontologist to 

 the Geological Survey, and quite recently President of the Geological 

 Society of London. Owing to the great amount of matter contained 

 in this work, the publication has been somewhat delayed, and 

 students of geology have been anxiously waiting for the appearance 

 of the long-promised volume. It is only right to remark that, 

 although bearing the name of Phillips, Part II. contains very little 

 of the original text — less indeed than the part edited by Prof. 

 Seeley. This circumstance arises from the nature of the subject, 

 and from the great advances which have been made in stratigraphical 

 geology, both at home and abroad, no less than in palaeontology, 

 during the last 30 years. The original illustrations of organic remains 

 have been culled and added to, and these now form a series of 33 

 plates, which contribute much to the instructive character of the 

 work before us. 



The publishers have been fortunate in securing the services of Mr. 

 Etheridge for this great task, requiring qualifications which he 

 probably possesses to a greater degree than any of his con- 

 temporaries. He has had immense experience as Palaeontologist 

 to the Survey, whose valuable collections it was his duty to sift 

 and in part arrange during the many years he was at Jermyn 

 Street. His two addresses from the Chair of the Geological 

 Society afforded also an intimation of the great stores of knowledge 

 which he had accumulated. Moreover, his well-known industry 

 and peculiar aptitude for arranging facts in a tabular form eminently 

 fitted him for the work he has undertaken. The records of geological 

 literature are becoming so vast that it requires an almost gigantic 

 industry to deal with them. Hence the size of publications, nowadays, 

 is almost more portentous than their number, and in this case it has 

 evidently been a difficult matter to condense the subject within the 

 limits of a single volume. 



A bird's eye view of the geology of the British Isles in the shape 

 of a small map constitutes the frontispiece. The general result is 

 sufficiently accurate considering the smallness of the scale, but in 

 one or two cases (Cornwall for instance) the colours denoting Granite 

 and Basalt respectively have got transposed. The author still depicts 

 the great mass of the Scotch Highlands as Lower Silurian ; and 

 indeed who shall gainsay him in the present state of the controversy ?
