Waterbound Macadamised Roads, Tar Treatment of Road Surfaces, Bituminous 
Roads, Bituminous Carpets, Waves and Corrugations, Paved Streets and Con- 
crete Roads. Mr. Boulnois points out that the attempts made in Great Britain 
to construct hard-surfaced conerete roads have not met with much _ success, 
although in the United States of America, Canada, and elsewhere many millions 
of square yards of roads of this form of construction have been laid. It is esti- 
mated that upwards of 50,000,000 square yards of such roads exist in America 
alone, and that, with few exceptions, they are a success. He ascribes the failure 
of these roads in England to lack of accurate knowledge of the behaviour of 
concrete and of methods of manufacture to suit the conditions. The book con- 
tains numerous definitions and specifications for various road-making materials. 
It is exceptional in that it contains neither cost data nor reproductions of high- 
way photographs, The former are excluded owing to the present fluctuation in 
material and labour costs, and the latter because “they are of little practical 
value.” The volume is well printed and the contents are clearly articulated. It 
forms a valuable contribution on a subject which is of very great interest and 
importance in Australia. 
Foot Care and Shoe Fitting—By W. L. Mann, M.D., and S. A. Folsom, M.D., 
pp. 124, with 58 illustrations. P. Blakiston’s Son & Co. Philadelphia. The close 
association of the authors with the United States Navy has enabled them to 
_ draw-their data from a variety of sources, and the result is a useful book 
of reference for officers interested in the marching capacity of their troops, The 
care of the feet is of no less -importance than the fit of the boots, and both 
aspects of the problem are fully discussed. ‘The treatment of the different ail- 
ments of the feet is an important section of the book. 
Animal Life and Human Progress —kKdited by Arthur Dendy, D.Sc., F.RB.S. 
(Professor of Zoology in the University of London), pp. ix. + 227, Constable’ 
and Co. Ltd., London. The volume comprises nine lectures delivered at King’s 
College, London, in 1917-18 under the auspices of the Imperial Studies Com- 
mittee of the University of London. ‘The joint purpose of the contributors 
was to emphasize and illustrate the importance of zoological science from the 
point of view of human progress, and judging by the results it is doubtful 
whether this could have been better accomplished. The subjects chosen are 
of intense interest ‘and most attractively written. As Professor Dendy, in his 
article on “‘ Man’s Account with the Lower Animals,” points out, the zoologist 
plays a great part, not only in the amelioration of the conditions of human 
life, whether in war or peace, but also in the education of the’ public with 
regard to many matters which have a very direct bearing’ upon the future of 
the human race. The utilitarian aspect of the study of zoology is, of course, 
emphasized, so that the vast material resources of the animal kingdom might 
be fully exploited in the interests of mankind, but the various contributors 
have invested their subjects with a live interest which cannot fail to open the 
eyes of any reader to the value of biological studies, the investigation of which 
alone renders possible the scientific study of man himself in all his manifold 
relations. The doctrine of organic evolution looms large in several of the 
lectures, and a certain advance is to be observed from the position held by 
Charles Darwin. However, if, as explained in a prefatory note, some of the 
views appear in some cases to be subversive of modern biological doctrine, it 
must be remembered that biological thought is progressive. Were it otherwise, 
the claims of biological science to a foremost place in our educational system 
might well be considered questionable. It is unnecessary to more than give 
the titles of the lectures, and their distinguished contributors, to reveal the 
pleasure and the profit to be derived from a study of the volume. The com- 
plete series is—‘* Man’s Account with the Lower Animals,” by Arthur Dendy,
