The prices of the 1-inch maps are from Is. 6c?. to 8s. Qd. for Eng- 

 land (a few detailed drift maps at higher prices) ; \s. 6d. to 3s. for 

 Ireland ; 4s. to Qs. for Scotland ; of the 6-inch maps, 4s. to 6s. 



The 'Memoirs' of the Geological Survey date from 1845. Four 

 volumes were consecutively numbered ; vol. 1 and vol. 2 (in two 

 parts) contain several papers. The other two volumes and all later 

 ' Memoirs ' are each confined to one subject or district. There are 

 twenty-four volumes in all. 



Memoirs or Explanations of sheets of the map have been issued 

 since 1859; those published are — for England 49; Ireland, 92; 

 Scotland, 17. 



British fossils are described in 'Decades' (thirteen published, from 

 1849) and 'Monographs ' (four published, from 1859). 



' Mineral Statistics ' have been published annually from 1853 to 

 1882; but in 1883 the Mining Eecord Office, in which these were 

 prepared, was removed to the Home Office, and the statistics will in 

 future be issued as parts of the Eeports of the Inspectors of Mines. 



No official general map has been issued by the Survey, but the 

 following maps, on scales varying from seven to eleven and a half 

 miles to the inch, have been published by the directors of the respec- 

 tive surveys ; they are reductions of survey work to date ; British 

 Islands, by A. C. Ramsay, 1878 ; England and Wales, by A. C. 

 Eamsay, 4th ed, 1879; Ireland, by J. B. Jukes, 1867; Ireland, by 

 E. Hull, 1878 ; Scotland, by A. Geikie, 1876.

I. — The Student's Handbook of Physical Geology. By A. J. 

 Jukes-Browne, B.A., F.G.S. pp. 514. (London : George 

 Bell & Sons, 1884.) Price Qs. 



THE present volume, dealing with dynamical, structural, and 

 physiographical geology, is intended to occupy an intermediate 

 place between the elementary manuals of geolog}^ and the elaborate 

 treatises of Dr. A. Geikie and Prof. A. H. Green. The subjects of 

 paleeontological and historical geology are left to form another 

 volume, after the plan adopted by Prof. Green ; let us hope, how- 

 ever, that the author will not wait for that perfection which never 

 comes, but complete his work without allowing a very long interval 

 to elapse. 



The work before us bears evidence of great care and extensive 

 research, while the definitions are clear and amply illustrated by 

 diagrams and references to phenomena exhibited in various parts of 

 the world. Seeking inspiration, with due acknowledgment, from the 

 works of De la Beche, L^'ell, Jukes, Eainsay, and A. Geikie, and 

 making good use of his own experience, the author has produced an 

 excellent introduction to the principles of geology, combined with 

 an account of rocks and rock- structure, and of the methods by which 

 the surface-features of the land have been sculptured.
