HOST-PARASITE RELATIONS BE- 

 TWEEN MAN AND HIS INTESTINAL 

 PROTOZOA. 



By Robert Hegner. The Century Company 



$3 -50 5! x 8f ; xiii + 2.31 New York 



This is the first volume in the Century 

 Biological Series, of which Dr. Hegner is 

 general editor. The purpose of the book 

 is "to gather together the more relevant 

 ■data regarding the host-parasite relations 

 of the intestinal protozoa of man and to 

 present them in logical order in such a 

 ■way as to bring out the state of our 

 knowledge with special reference to the 

 desirability of further studies." The 

 treatment is excellent, but there is a sparse- 

 ness of illustrations for which there seems 

 no compelling reason. There is a bibliog- 

 raphy of 15 pages, and author and sub- 

 ject indices. We extend a hearty welcome 

 to the series which this volume inaugu- 

 rates at a high level of excellence. 



ECONOMIC BIOLOGY FOR STUDENTS 

 OF SOCIAL SCIENCE. Part I. Harm- 

 ful and Useful Animals. 

 By Philippa C. Esdaile. 



University of London Press 

 js. 6d. 5! x 8|; xv + 175 London 



Specialization goes ever further and 

 finer. Here we have an elementary zool- 

 ogy for students of what we call in this 

 country "domestic science." It picks out 

 for description and illustration (both ex- 

 cellent) those animals and plants "which 

 are, or may be, closely associated with 

 man and his household." The present 

 Part I deals with animals, such as bath 

 sponges, pin-worms, bed bugs, cock- 

 roaches, spiders, etc. Part II will dis- 

 cuss "Animal and Vegetable Products." 

 The book should serve extremely well the 

 class for which it is intended. And fur- 

 thermore every householder will find it 

 an interesting book to have about. 



SEASHORE ANIMALS OF THE PACIFIC 

 COAST. 



By Myrtle R. Johnson and Harry J. Snook. 



The Mac-mil I an Co. 

 $7. 50 6 x 0)\; xiv + 659 New York 



This stately and beautifully illustrated 

 volume is intended to furnish those 

 interested in natural history, whether 

 professionally or as amateurs, with non- 

 technical accounts of the structure and 

 habits of the common seashore animals of 

 the west coast of North America. The 

 arrangement of the book is according to 

 the taxonomic series. It covers only the 

 invertebrates, with a short final chapter 

 on the Chordata. It is very well done, 

 and will have an even wider field of use- 

 fulness than that contemplated in its plan. 

 There is a bibliography of 14 pages, a 

 glossary, and a detailed index.

 $3 .50 5^ x 9; xx + 1x5 Boston 



This is a popular, but at the same time 

 soundly scientific treatise on reptiles and 

 amphibians, with special emphasis on 

 their ecology, habits, and behavior. It 

 is beautifully and extensively illustrated, 

 contains a short selected bibliography, 

 and is well indexed. It is an example of 

 the highest type of popular natural his- 

 tory writing. A part of the material 

 was used as a series of Lowell Lectures.
