KELLOGG'S INSECT STORIES 



By Vernon L. Kellogg, Professor in Leland Stanford University. Illustrated. 

 298 pp. Large 12mo. $1. .SO, net. By mail, $1.02. 



Professor Kellogg has, in this volume of strange, true stories, sueceed- 

 ed in describing the habits of certain insects in so fascinating a way that 

 there are few people, either old or young, who will not be held by its 

 charm. 



The Nation: — The author is among the few scientific writers of distinction 

 who can interest the popular mind. No intelligent youth can fail to read it with 

 delight and profit. 



C. A. Stkbkins, Chico (Cal.) Normal School: Keilogg's "Insect Stories" is the best 

 book of its kind that I have ever seen. Our student teachers use it continuously. 



RUSSELL & KELLY'S LABORATORY 

 MANUAL OF FIRST YEAR SCIENCE 



By W. S. C. Russell, Director of Science in the Central High School, Springfield, 

 -Mass , and H. C. Kelly, Instructor in Science in the same. 4to. 75 cents. 



A collection of 35 experiments based upon the widely known First 

 Year Science Course in SiJringfield, which aims to lay a broad founda- 

 tion for later more specialized work in science and to furnish a fund of 

 useful information for pupils who do not intend to carry on their scien- 

 tific studies. The wide range and practical character of the experi- 

 ments are indicated by a few of the titles of exercises: Meter Read- 

 ings, Coffee Tests, Home Heating, Hot Water Tanks, The Electric Bell, 

 Constellations, Standard Time, Weather Report. Cost of Home Lights, 

 A Study of Mould, and Study of Building Stones. 



FITZ'S PHYSIOLOGY AND HYGIENE 



By Cieorge W. Fitz, M.D., formerly Assistant Professor of Physiology and 

 Hvgiene in Harvard University, and sometime Teacher of Science in Cook County 

 Normal School, 111. xiii + 357 pp. 12mo. $1.12. 



Community hygiene receives as much attention as personal hygiene. 

 Such matters as heating, ventilation, sewage, water supply, the com- 

 munication of disease (including tuberculosis), and the maintenar 

 the body's powers of resistance to infection, are treated with some 

 approach to adequacy for ■ almost the first time in an elementary text- 

 book. Physiological processes in the lower forms of life are constantly 

 used to illustrate corresponding processes in man. The pupil is thus 

 helped to review and apply his studies in botany and zodfi 



MOORE'S PHYSIOLOGY OF MAN 

 AND OTHER ANIMALS 



By Anne Moork, vii + 212 pp. 12mo. So i 



A very elementary treatment of pure physiology as distinguished from 

 anatomy. It emphasizes strongly the fact that physit .logical processes 

 in man, in the lower animals and in plants are governed by the same laws.
