lurched forward, bowed majestically over, and, almost 
before we knew what was happening, went hurtling 
down the cliffs and gullies. It cleared some hundreds 
of feet at a leap ; then striking a projection, bounded 
off, leaving an ugly sear behind, and thundered on down 
the crags, smashing off corners, crashing into the screes 
in the gullies and splashing up the snow like water.

Pretty pastime ! yet landowners are but human after 
all, and might not unreasonably demur to much of this 
kind of thing. There is no evidence that in his scrambles 
Dr. Baker took any notice of geology, botany, or any-

S implied by the title, Dr. Brown’s ‘“‘ Suggestion 
and Menta] Analysis” brings together the 
widely divergent views of the two principal schools 
of psychotherapy. It is an attempt to harmonise 
the theory and practice of the hypnotists, suggestion- 
ists, and autesuggestionists, on one hand, and of the 
psycho-analysts on the other. It is generally claimed 
by the partisans of each school that its method is 
_ exclusively the best suited for the treatment of those 
forms of psychoneuroses in which mental therapy is 
Indeed, as Dr. Brown points out, extremists 
of both schools agree in disclaiming any possibility 
of a synthesis of their methods. In practice, however, 
it not seldom works out that such disclaimers are 
ignored, even by the purists. Dr. Brown argues that 
the various methods of psychotherapy can be advan- 
tageously employed in combination. He bases his 
views upon a very large number of typical clinical 
cases which have passed through his hands both in 
civilian practice and as a result of the special con- 
ditions due to the War. With regard to the latter 
eases, Dr. Brown worked mainly by suggestion and 
hypnosis, and with marked success. He now advocates 
a judicious use of all the methods, some of which are 
more especially adapted to one type of case and some 
to others. He thus, on empirical grounds, declares 
himself to be an eclectic. 
The book is elementary—even popular—but it 
touches upon most of the points which are treated 
at length in the large and continually growing literature

of psychotherapy. The first chapters deal with 
generalities on suggestion and the subconscious, and 
sketch briefly the theories and methods of the analysts. 
Several interesting case-histories are given in some 
detail to illustrate the dissociation due to hysteria 
and hysterical epilepsy. Hypnosis is contrasted with 
suggestion, and is itself declared to be a form of dis- 
sociation ; in consequence of which the conclusion 
is—rightly—drawn that frequent hypnotising of a 
patient is dangerous. Nevertheless, hypnosis is a 
valuable procedure to employ in certain cases. Indeed, 
all proved-methods are valuable. This is the general 
conclusion of the book, in which such divergent views 
as those of Charcot, Bernheim, Freud, Jung, Coué, 
and others are considered. 
The more scientific and therapeutic part of the 
volume is supplemented by three chapters on the 
“philosophical background,” which consist of a sum- 
mary exposition and criticism of the philosophy of 
M. Bergson. It is true, as Dr. Brown remarks, that 
“every revolution in scientific theory synchronises 
closely with the development of new ideas, and even 
new systems, within the domain of philosophy” ; 
and no doubt Bergson’s philosophy synchronises to 
some extent with the rise and growth of recent psycho- 
therapeutic theory and practice. There are obvious 
similarities in both. But it is not obvious why these 
chapters should have been included in a book on 
psychotherapy ; and their inclusion makes it appear 
rather overweighted with speculation. The present 
is the third edition of the book ; and it is clear that 
this excellent elementary presentation of the theory 
and practice of “ mind cure ” meets the good reception 
it deserves at the hands of the public. There is a 
good index.

Tue collections brought together by the zealous care 
of Mr. Watson in the Sedgwick Museum have been 
of great service in technical geology. Probably much 
may still be added to the samples of cement and 
artificial stone described in the present volume, as 
these materials become still more favoured by architects 
and engineers. The labour and art of the mason may 
decline, but the production of durable cements for 
covering walls, the colouring of them until they surpass 
in brilliance the painted surfaces of Roman times, and 
the imparting of increased delicacy to moulded work 
in stucco, are alike honourable and artistic occupations. 
The materials of artificial slabs are largely natural
