The Principles of Physics aims to supply the demand for an 

 accurate, interesting, usable text-book of present-day physics, 

 suitable for high schools and elementary courses in college. 



The size and general features of the Introduction to Physical 

 Science in its present revised form have been changed little, 

 but numerous slight changes have been made throughout 

 the work which will be found improvements and which will 

 make it more acceptable to those using it. 



In general plan the revised Elements of Physics is similar 

 to the original book, though distinctly less inductive. Many 

 improvements in method of presentation have been intro- 

 duced as a result of the author's experience as a teacher 

 and a text-book maker. Recent advances in the industrial 

 applications of physical principles receive due attention. 

 The department of mechanics is given full treatment, and a 

 large number of problems and practical exercises is furnished 

 throughout the book. 



Physical Experiments contains the laboratory exercises 

 required for admission to Harvard University and to many 

 other colleges.
