Reviews — Brief Notices. 377 



owing to omissions in the last volume necessarily made up in this. 

 Several improvements have been made, notably in the attempt to 

 give bibliographic exactness to authors' names and in having a more 

 definite plan in the Index. It is not too much to say that the 

 publication reflects the highest credit on the new Librarian, 

 Mr. C. P. Chatwin. Few people realize the incredible labour it is for 

 one man to compile such a book, with the pressing duties of a library 

 and its visitors to contend with, even when assisted by a competent 

 junior, and. we must all feel profoundly thankful that in this volume 

 we recognize that the most valuable publication of the Geological 

 Society of London has entered on a new lease of life with renewed 

 vigour. It is by far the best Eecord of Geological Literature that is 

 published, and is as useful to the amateur as to the professional. 



VII. — Brief K"otices. 



1. The Crust of the Earth. — The crust of the earth comes 

 in for a good deal of study in the Journal of Geology, vol. xxii, 

 No. 2, 1914. W. H. Hobbs continues his papers on the mechanics 

 of formation of Arcuate Mountains, Joseph Barrell continues his 

 on the strength of the earth's crust by writing on " The Regional 

 Distribution of Isostatic Compensation", and T. C. Chamberlin 

 continues the diastrophism and the formative processes by " The 

 Testimony of the Deep-sea Deposits". Important preliminary 

 results of measurements of the Ptigidity of the Earth are contributed 

 by A. A. Alichelson. The first and last papers are well illustrated 

 and can be easily followed. 



2. Lancashire and Cheshire. — The Proceedings of the Liverpool 

 Geological Society, toI. xi (4), 1913, contain papers of markedly 

 local interest. Excavations at Liverpool and Birkenhead have been 

 watched and recorded by C. B. Travis and T. A. Jones, and plants 

 and other remains are recorded from Seaforth. W. T. Walker writes 

 on the Boulder-clay of Jforth Wirral, and H. C. Beasley describes 

 the Storeton find of 1912 and reproduces Morton's map of the faults 

 in the Storeton area. Numerous references occur throughout to the 

 variety of rocks found in the Lancashire-Cheshire Boulder-clay, but 

 we do not remember any special paper deuling with the subject 

 which would probably be worth working up. 



3. Chalk of Suffolk. — Mr. P. G. H. Boswell has given a sketch 

 of the Chalk of Suffolk in the Journ. Ipswich Field Club, vol. iv, 

 1913. He records the successive zones from that of Belemmtella 

 mucronata to Holaster plamis, and although he does not give a list 

 of his fossils, the few he quotes are sufficiently convincing. The 

 thickness of Eocene beds to the east and south of the count}' may 

 hinder the publication of a zonal sketch-map of the county, but 

 Mr. Boswell's paper is based on field work and personal observation 

 and will be a sufficient guide to any one familiar with the Chalk 

 and its fauna, especially when read in conjunction with his paper 

 "On the Age of the Suffolk Valleys" issued in vol. Ixix of the 

 Quarterly Journal of the Geological Society, 1913 (1914).
