ing and coating; and, while teaching the facts, to impart the spirit 

 of science, that is to say, the spirit of our civilization and progress. 



Alexander Macfarlane, Prof, of 

 Physics, University of Texas : I con- 

 sider that the principal features of 

 the book its clearness and accuracy 

 of statement, its information being 

 up to date, and the practical nature 

 of the instruction make it valua- 

 ble as a first text-book in Physics in 

 high schools and academies, and es- 

 pecially for those institutions that 

 prepare for the universities. 



I. Thornton Osmond, Prof, of 

 Physics, State College, Pa. : For 

 selection of matter and method of 

 treatment, for comprehensiveness, 

 brevity, clearness, and accuracy, for 

 the simplicity and value of experi- 

 ments, it was, and yet is, unrivalled 

 as a text-book for high school and 

 academic work. 



George E. Gay, Prin. of High 

 School, Maiden, Mass. : With the 

 matter, both the topics and their pre- 

 sentation, I am better pleased than 

 with any other Physics I have seen. 



J. P. Naylor, Prof, of Physics, De 

 Pauw University; In its scientific 



spirit, and in accuracy and clearness 

 of statements of principles, I know 

 nothing that is its superior. The ex- 

 tent to which the work is carried is 

 also about what can be well done in 

 the time our schools usually have to 

 give to the subject. It is used in 

 preparatory work at this University 

 as the best we can get. 



0. C. Kinyon, Teacher of Physics 

 in High School, Syracuse, N. Y. : It 

 not only insures an interest in the 

 study but tends to thoroughly arouse 

 those powers of observation, the de- 

 velopment of which is the especial 

 province of scientific study. 



B. C. Hinde, Professor Natural 

 Science, Trinity College, N. C. : I 

 have used Gage's Introduction to 

 Physical Science for two years, and 

 I consider it the best book published 

 for its purpose. It is strictly in 

 accord with the best modern teach- 

 ing of Physics. I have made it a 

 point to call the attention of my stu- 

 dents to this book that they may use 

 it in their teaching.

manual has been prepared especially to accompany the 

 " author's text-books, but is adapted for use in connection with 

 any good text-book on the subject. The left-hand page contains 

 cuts of apparatus to be used, directions for performing experiments 

 (upwards of one hundred in number), and questions to be an- 

 swered in connection with the experiments. Suggestions to 

 teachers, the needed tables, etc., are provided at the beginning. 

 The right-hand pages are left blank for the pupil's notes.
