1917. 
THIS valuable work forms the first section of the third volume of 
the Handbuch der regionalen Geologie. The manuscript appears 
to have been completed by 1914, but the War delayed its publication, 
and the date of issue 1s given on the cover as 1917. Even now it is 
difficult to procure the volume in England. 
The first twenty-four pages are devoted to the Morphology of the 
British Isles, England and Wales being dealt with by Dr. A. M. 
Davies, Scotland by Professor Gregory, and Ireland by 
Professor Cole. Then follows a short note on British Karthquakes by 
Dr. C. Davison, and the remainder of the work, more than 300 pages, 
is devoted to stratigraphy. All the sections relating to Ireland are 
written by Professor Cole, and in most of the geological systems the 
igneous rocks are discussed by Mr. Harker. In the case of the 
Ordovician and Silurian systems, however, the volcanic rocks are 
described along with the sedimentary deposits, while the intrusive 
rocks are dealt with separately by Mr. Harker. With regard to the 
other sections, Professor Gregory describes the pre-Cambrian of 
Scotland, Professor Watts the pre-Cambrian of England and Wales 
and the Cambrian and Ordovician of Great Britain; Professor O. T. 
Jones takes the Silurian, and Dr. Evans the Devonian, while 
Professor Kendall is responsible for the Carboniferous, Permian, 
and Quaternary. The Trias and Rheetic, in accordance with German 
custom, form two distinct sections, which are written by Mr. Linsdall 
Richardson and Professor Boswel!. The Jurassic and Lower 
Cretaceous are dealt with by Dr. A. M. Davies and Professor Boswell, 
and the Upper Cretaceous and Tertiary by Mr. Osborne White. 
Finally there is an appendix on the Channel Islands by Mr. Parkinson. 
In the GEoLtocicaL MAGAZINE it is not necessary to add that these 
names are a sufficient guarantee of accuracy. 
‘The space allotted to morphology is too small to allow of 
an adequate treatment of so complex a subject; but the strati- 
graphical section is a very complete account of British stratigraphical 
sclence as it was a year or two before the War. It is approximately 
on the same scale as Jukes-Browne’s Stratigraphical Geology, but 
local detail is not so strongly emphasized as in that work. It is 
not that the local detail is omitted, but that it is more subordinated
