Reviews—New Geological Map of Ireland. 43 
IV.—A New Geotocicat Map or I[retanp. 
ESSRS. J. BARTHOLOMEW & CO. have just published a ‘‘ Map 
showing the Surface Geology of Ireland, reduced chiefly 
from the Ordnance and Geological Surveys under the direction of 
Sir Archibald Geikie, D.Sc., LL.D., F.R.S., late Director-General 
of the Geological Survey.” Scale, 10 miles to l inch. Price 6s. 
The map is on the same scale as Sir A. Geikie’s maps of England 
and Wales and Scotland, issued by the same publishers, and is executed 
with even greater attention to detail; in fact, where the covering of 
drift is absent, the amount of detail shown is wonderful. At the same 
time, from the point of view of those who are neither agriculturists. 
nor glacialists, it is a great pity that the map has not been issued as 
a solid-geology map, like its English and Scotch companion maps. 
The explanation is as follows :—The map was printed at the suggestion 
of the Department of Agriculture for Ireland, whose original intention 
was to have two maps, one showing solid geology and the other drift. 
geology. Subsequently, however, they decided to have only one map, 
and chose the dritt map as best suited to their requirements. It is to 
be hoped that Sir A. Geikie and Messrs. Bartholomew may see their 
way to issuing, at the earliest possible date, a solid-geolovy map, as 
the geological structure of the country is very much obscured by the 
drift, although it should be mentioned that the boundaries of the 
underlying formations beneath the drift are given. Tio make them 
out, however, requires minute study, so that a far better general idea 
of the structure of the drift-covered country is obtainable from 
Professor Hull’s map, in spite of its less detailed character.

(J\HIS little work is one (No. xi) of a series of illustrated geological 
guidebooks to various districts in Europe. They have all been 
prepared by thoroughly qualitied writers, among whom are to be 
found such well-known names as those of E. W. Benecke and 
A. Tornquist. 
The volume before us is devoted to that beautiful and much 
frequented part of Switzerland known as the Bernese Oberland, which 
will conjure up for many a reader the most delightful recollections of 
long rambles among its mountains and valleys. It is divided into 
a number of routes and branch routes, and under each of these the 
physical and geological features are described with as much detail as. 
the limits of space will permit. Some of the illustrations are in 
outline, others are reproductions from photographs, the latter mostly 
provided with key-plates, the different classes of rocks being indicated 
by the usual methods. There are also two plates, slightly tinted, 
from drawings made by the author to illustrate the Aletsch laccolith.
