A BRIEF COURSE IN 

 GENERAL PHYSICS 



.I.2O 



By GEORGE A. HOADLEY, A.M., C.E., 

 Professor of Physics, Swarthmore College 



A COURSE, containing a reasonable amount of work for 

 an academic year, and covering the entrance require- 

 ments of all of the colleges. It is made up of a reliable 

 text, class demonstrations of stated laws, practical questions 

 and problems on the application of these laws, and laboratory 

 experiments to be performed by the students. 

 ^j The text, which is accurate and systematically arranged, 

 presents the essential facts and phenomena of physics clearly 

 and concisely. While no division receives undue prominence, 

 stress is laid on the mechanical principles which underlie the 

 whole, the curve, electrical measurements, induced currents, 

 the dynamo, and commercial applications of electricity. 

 ^| The illustrative experiments and laboratory work, intro- 

 duced at intervals throughout the text, are unusually numerous, 

 and can be performed with comparatively simple apparatus. 

 Additional laboratory work is included in the appendix, to- 

 gether with formulas and tables. 



HOADLEY'S PRACTICAL MEASUREMENTS IN 

 MAGNETISM AND ELECTRICITY. $0.75 



THIS book, which treats of the fundamental measurements in elec- 

 tricity as applied to the requirements of modern life, furnishes a satis- 

 factory introduction to a course in electrical engineering for secondary 

 and manual training schools, as well as for colleges. Nearly 100 experiments 

 are provided, accompanied by suggestive directions. Each experiment is 

 followed by a simple discussion of the principles involved, and, in some 

 cases, by a statement of well-known results.
