General Physics 



A Treatise on Natural 

 Philosophy 



Published by The McGraw-Hill Book Co., 

 New .York, 1916; Price, $3.00 postpaid. 



This textbook, with its brevity and clearness, its 

 direotness of treatment and its freedom from tedious 

 repetition of the commonplaces of High School Physics, 

 was intended to do away with the usual excessive 

 amount of classroom coa<5iing which is the despair of 

 every physics teacher who aims to develop the power 

 of analytical thinking and who tries therefore to hold 

 his students accountable for mathematical ideas, 

 mathematical formulations (not mathematical form- 

 ulas, please note) and numerical calculations. And 

 the use of the book in the classroom seems to show 

 that it does in some measure accomplish what was 

 intended. The studente do read it, it tends to focus 

 their attention on fundamentals, it helps to an unpre- 

 cedented extent (in the author's experience) to form 

 precise ideas, and it enables the student to devour 

 numerical problems.
