This Brief Course in General Physics is designed to 

 provide a text-book for High Schools and other Second- 

 ary Schools that can be completed, with a reasonable 

 amount of work, within an academic year. In its prepara- 

 tion the author's aim has been to present the essential 

 facts and phenomena of physics in a clear and concise 

 manner, and in such a way as to awaken the interest of 

 the student in the subjects treated, and by awakening this 

 interest to secure familiarity with the action of physical 

 forces, and the laws which govern those forces. 



The book is constructed on the principle that to in- 

 sure the greatest benefit from the study of Physics, there 

 should be a coordination of (i) a rehable text, (2) class 

 demonstrations of stated laws, (3) practical questions and 

 problems on the application of these laws, and (4) per- 

 sonal experimentation in the laboratory. 



Copies of the book will be sent, prepaid, on receipt of the price,
