NEW VOLUME. 



THE ELEMENTS OF PHYSICS. 



A College Text-Book. By Edward L. Nichols and William S. Franklin, both of the Department of Physics, Cornell Uni- 

 versity. Vol. II. Electricity and Magnetism. 8vo, cloth, $1.50 net. Already published. Vol. I. Mechanics and 

 Heat. 8vo, cloth, $1.50 neiS. In preparation. Vol. III. Sound and Light. 



The first volume, which was issued about January 1, 1896, is devoted to the subject of Mechanics and Heat, the second to 

 Electricity and Magnetism, and the third to Sound and Light. No attempt has been made in this work to produce a com- 

 plete manual or compendium of experimental physics. The book is planned to be used in connection with illustrated lec- 

 tures, in the course of which the phenomena are demonstrated and described. The authors have accordingly confined 

 themselves to a statement of principles, leaving the lecturer to bring to notice the phenomena based upon them. In stating 

 these principles free use has been made of the calculus, but no demand has been made upon the student beyond that sup- 

 plied by the ordinary elementary college courses on the subject.
