physical and chemical elements of the animal to produce the 

 results. He points out the significance of such reactions as the 

 basis for the psychology of the animal. In all there are ten of these 

 essays. They are exceedingly interesting and stimulating. Dr. 

 Loeb's style is simple so that the methods of procedure, the 

 results and the conclusions, are perfectly clear even to one who 

 has not had biological training. He makes apparent that many 

 of the so-called vital processes are explicable on a physical and 

 chemical basis. Judgments will differ as to how far it is safe to 

 conclude from such evidence that all vital phenomena are to 

 be so explained. 



Seeing Nature First, by Clarence M. Weed, 309 pages; J. B. 

 Lippincott Co., $1.50. 



This book has almost the charm of the writings of William 

 Hamilton Gibson. Mr. Weed has facility of expression, a keen 

 sight, and the artistic sense that made Gibson's books take first 

 rank as nature-studies. The title of the book indicates its pur-

 such a deluge of nature books, especially nature readers, that the 

 nature enthusiast is afraid constantly people will read about 

 nature rather than study nature herself. This book, however, 

 makes you really want to get out-of-doors and see some of the 

 things that Weed has seen and described so enticingly. The book 

 is seasonal, divided into spring, summer, autumn, and winter, with 

 most of the space devoted to summer. 



The illustrations are partly photographic, partly pen and ink 

 sketches. The frontispiece is in color. The descriptions include 

 both animals and plants, the animal material predominating.

 $2.25. 



This book is an evidence of the tendenc}^ now to be noticed 

 amongst all of the sciences towards rearranging the materials of 

 science in terms of education through subjects that are vocational, 

 industrial, agricultural and related to the home. Much of the 

 material found in the book is identical with that already published 

 in books upon bacteriology, botany and hygiene. The n^w
