written much on the subject of science for young people, par- 

 ticularly, Thomas M. Balliet, Thomas H. Briggs, John Dewey,

 F. Woodhull. To the many science teachers who have been

 to its present state, the authors make full acknowledgment for 

 much help and inspiration. Acknowledgment for illustrative 

 material is made in the text. The drawings were nearly all

 the entire proof and made many valuable suggestions : Mr. 

 M. C. Leonard, Vice-principal, Dickinson High School, Jersey
