in its treatment, and not only cites many instances of animal development 

 and repression gleaned from other countries, but throughout impresses the 

 reader with the fact that the author is dealing with world-wide principles 

 and problems. 



The author is to be congratulated on successfully having undertaken an 

 enormous task. The general plan of the volume is best illustrated by a 

 citation of the chapter headings, of which there are nine, the first intro- 

 ductory, the last conclusive, and the remainder being grouped, four and 

 three respectively, in still larger divisions, Part I dealing with man's deliberate 

 interference, and Part II with his indirect interference with animal life. 

 The four chapters of Part 1 bear the following legends — " The Domestication 

 of Animals " ; " Deliberate Destruction of Animal Life " ; " Protection of 

 Animal Life " ; " Deliberate Introduction of New Animals " : those of 

 Part II — "The Destruction of the Forest " ; " Influence of Cultivation and 

 Civilisation " ; " Animals Introduced Unawares." All of these are sub- 

 divided still further into sections. Chapter V, for instance, including three 

 under the headings " Animals Introduced for Utility," " for Sport," " for 

 Amenity." It will thus be readily seen that the book deals with all possible 

 phases of the main subject in a comprehensive, scholarly, and able manner. 

 There is, moreover, an excellent and complete index. 



The maps form an important feature of the book, graphically illustrating 

 such features as the shrinkage in the distribution of the red deer, the spread 

 of the squirrel, or the influence of man-made obstructions on salmon rivers. 

 Of other illustrations many are good, but some are so poor that they might 

 well have been omitted. 



This authoritative treatise should find a place in every reference library.

Wasp Studies Afield. By Phil and Nellie Rau. [Pp. 372, with 68 figures.] 

 (Princeton : University Press, N.J. Price $2.00 net.) 



This is an interesting little book, dealing mainly with the field habits of 

 some of the solitary wasps. There is a single chapter on certain sociable 

 species. Altogether some sixty species are dealt with, the habits of the 

 majority being here described for the first time. 



A large portion of the book goes to the description of experiments carried 

 out to test the homing instincts, etc., of various selected wasps. In con- 

 clusion, there is a chapter, entitled " General Considerations," devoted to 

 summarising and discussing the results obtained. There is a short but fairly 

 complete index. 



The book is written in a rambling style, but makes very interesting 

 reading and suppUes the wasp specialist with a great deal of new information.

AIt.CH.3:OLOGY 



Pre-Palseolithic Man. By J. Reid Moir, F.R.A.I. [Pp. 67, with 29 plates.] 

 (Ipswich : W. E. Harrison.) 



Of the original work in prehistoric anthropology which has been carried 

 on during the last ten years, none has been more important than that of the 

 author of this book. As is now well known to all those who follow the 

 advances of natural science, Mr. Reid Moir has been studying for years 

 certain flints which are found below the Red Crag of East Anglia, which are 

 therefore of Pliocene date, and are well known as Rostro-Carinate imple- 

 ments. Mr. Reid Moir has always beheved that these peculiar flints were 

 artificially chipped, and he has succeeded in convincing the majority of 

 those competent to form an opinion that some, at least, of the specimens
