has been covered and the mass of material which they 
have had to bring within the compass of their little 
book, the authors have produced an excellent and very 
readable popular account of the peoples of the later 
prehistoric ages in North-Western Europe and, in 
particular, of Britain. Without entering into detailed 
criticism, it may be suggested that more stress might 
have been laid upon early trade connexions between 
Britain and the Baltic and their bearing upon the 
archeological and ethnological problem. The synoptic 
chronological chart of ancient civilisations in parallel 
columns will be invaluable to those who have not madea 
special study of prehistoric archeology. 
Der fossile Mensch. Von E. Werth. Zweiter Teil. 
Pp. 337-576. (Berlin: Gebriider Borntraeger, n.d.) 
12s. 8d. 
Tus is the second part of a comprehensive treatise on 
the handiwork of early man. It begins with the middle 
of a sentence on p. 337 and ends in a similar way on 
p. 576, and the reviewer has not seen what went before 
or came after these broken sentences. The volume 
consists of a very detailed and exceptionally well. 
illustrated account of paleolithic flint implements, and 
gives information relating to the extinct fossil animals 
and plants associated with the various types of im- 
plements and to the problems of the glacial periods. 
Throughout the book very full bibliographical 
references are given to memoirs written in the German 
language, and occasionally to those written in French ; 
but works written in English and information which 
can only be obtained at first hand in English memoirs, 
such, for example, as that relating to the discoveries at 
Piltdown and elsewhere in Britain, are wholly ignored. 
Moreover, the views expressed in the book are strictly 
orthodox, and the author is very cautious in referring to 
matters which do not fall into the old scheme of inter- 
pretation adopted by him. 
Although the work is called ‘‘ Der fossile Mensch,” 
there is, at any rate in this part, no reference to the 
fossilised remains of man. The book is a valuable 
work of reference for flint implements and for German 
ideas regarding problems of chronology. The author 
.refers Pithecanthropus to the oldest interglacial period 
and assigns the Cromer Forest-bed to the same horizon.

Mr. CRAwrorb’s memoir covers an area which, as he 
points out, is not particularly well adapted to treat- 
ment on the lines of natural regions. In the main he 
contents himself with indicating the larger divisions, 
and has taken his units chiefly on a geological basis. 
On these lines he divides the area into three main 
natural regions—Andover, the belt of high ground 
between Basingstoke and Savernake, which is crossed 
by the Winchester and Newbury Road, and the Vale 
of Kingsclere. In addition, a portion of the London 
Tertiary basin and of the Vale of Pewsey come into the 
north-east and north-west corners respectively. Each 
of these is studied in detail in respect of its physical 
NO. 2795, VOL. 111] 
and economic aspects. In the latter section Mr. 
Crawford deals with a subject which in part he has made 
‘peculiarly his own, and his analysis of the relations of 
prehistoric Roman and modern settlements and of 
early and recent lines of communication in this area 
will be highly appreciated by archeologists and 
students of topography. 
A number of useful appendices deal with such 
subjects as measurements, grouping of parishes, pre- 
historic sites, Anglo-Saxon bounds, forest regions, 
place-names, and the like. The volume is well illus- 
trated by photographs and numerous plans prepared 
from the Ordnance Map.

Tuts book is prepared exclusively for the use of navi- 
gators and seamen who keep a record of the weather ; 
it is especially intended for the mercantile marine. 
There are many essentials in the keeping of the Meteoro- 
logical Log for the Meteorological Office, among which 
may be mentioned the uniformity of scales, much of 
which is new to the ordinary navigator. Instruments, 
if required, are loaned by the Meteorological Office, which 
in return for the instruments supplied claims possession 
of the Meteorological Log. Among the observations 
required are wind direction and force, barometer, 
temperature of air and sea, cloud, weather, state of 
sea, the set and rate of current, and other features of 
interest. The handbook shows how the observations 
should be made, and how the results are used for the 
advantage of seamen and others. 
The present-day navigator has many advantages 
quite unknown to navigators in bygone days, especially 
with respect to wireless reports, which enable any 
captain afloat to make for himself by the aid of 
messages from other adjacent vessels a synchronous 
chart showing the weather conditions by which he is 
surrounded. Storms may thus be avoided, and ad- 
vantage can be taken of favourable weather conditions.

Cours de chimie inorganique. Par Prof. Fréd. Swarts: 
Troisiéme édition, revue et augmentée. Pp. iv +734. 
(Bruxelles : M. Lamertin, 1922.) 50 francs. 
Tue third edition of Prof. F. Swarts’ “‘ Cours de chimie 
inorganique ” includes new matter dealing with the 
constitution of the atom, isotopes, and catalysis. It 
is perhaps the best book of its type that has appeared 
in French, but English students would probably prefer 
to learn chemistry from text-books of similar scope 
published in their own language.

H. Getman. Third edition, thoroughly revised and 
enlarged. Pp. xi+625. (New York: J. Wiley and

Pror. GeTMan’s “ Outlines of Theoretical Chemistry,” 
which appeared just before the War, received a drastic 
revision in 1918. The third edition has been brought 
up-to-date by the inclusion of recent work on isotopes 
and on atomic structure, but retains most of the 
features of the preceding edition.
