NOTES ON NEW BOOKS 



Biological Projection. Professor A. H. Cole, of the Chicago Normal 

 School, has for many years been experimenting with projection apparatus 

 as a means of illustrating the study of living plants and animals. His 

 results are incorporated in a book entitled "Manual of Biological Projec- 

 tion," published by the Neeves Stationery Company, Chicago. The book 

 gives very complete accounts of the various kinds of projection apparatus 

 and their management, and also very complete directions for exhibiting 

 living animals and plants. Especially interesting are the suggestions for 

 anesthetizing animals which are so active that in the normal condition 

 they could not be exhibited by means of projection apparatus. Very 

 many of these suggestions would be useful for work with an ordinary 

 microscope. Mention should also be made of the chapter which gives 

 directions for collecting many species of animals or plants and for keeping 

 them alive in aquaria. This chapter will be of value to many teachers 

 who do not use a projection microscope. 



General Physiology. The tendency in recent years has been to teach 

 human physiology in close connection with the biological sciences in our 

 high schools, rather than as an isolated topic concerned solely with the 

 human body. In other words, physiology is being taught as general phy- 

 siology, drawing a large, part of its material from various animals and 

 plants. To meet the demand for such a general treatment of physiology, 

 Dr. W. H. Eddy, of the New York High School of Commerce, has prepared 

 a text-book, which has been recently published by the American Book 

 Company. Throughout this book he has laid special stress upon the 

 physiological processes; and while retaining the human body as the main 

 subject of application, he has attempted to teach the universal application 

 of these processes to all diving matter. It would be possible to use the 

 book not only for the study of the human body, but also for a supplemen- 

 tary text in the study of zoology and botany. It is intended to be used as 

 supplementary to laboratory study, such as is outlined in the "Experi- 

 mental Physiology and Anatomy" by the same author. Such a book 

 deserves very careful trial by good teachers, because its general arrange- 

 ment indicates that in practice it will be found far superior to the usual 

 treatises limited to human physiology and anatomy. 



New Elementary Physiologies. In an article published in this magazine 

 in February 1906, page 67, it was pointed out that the great difficulty 

 with our present instruction in physiology and hygiene for elementary 

 schools arises from the fact that in presenting the subject every year, be- 

 ginning with the Third Grade, there is a large amount of useless and tire- 

 some repetition in all of the series of text-books which have been prepared 

 to meet the legal requirements. Especially has there been much repeti- 

 tion because authors have attempted to cover the entire subject in each 

 book. Professor L. H. Gulick, Director of Physical Education in the 

 New York City Schools, has attempted to overcome this difficulty by pre- 

 paring a new series of text-books, published by Ginn & Company. In
