THE 



EXPERIMENTAL SCIENCE SERIES. 



In neat 12mo volumes, bound in cloth, fully illus- 

 trated. Price per volume, $1.00. 



This series of scientific books for boys, girls, and students of every acre, was de- 

 signed by Prof. Alfred M. Mayer, Ph. D., of the Stevens Institute of Technology, 

 Hoboken, New Jersey. Every t>ook is addressed directly to the young student, arid 

 he is taught to construct his own apparatus out of the cheapest and most common 

 materials to be found. Should the reader make all the apparatus described in the first 

 book of this series, he will spend only $12.40. The remaining books of the series will 

 treat in the same cheap and simple manner of Heat. Electricity, and Magnetism. 



The series appears as the joint work of two authors. Prof. Mayer performed every 

 experiment in the presence of Mr. Barnard, and Mr. Barnard wrote out and prepared 

 the book for the press. Prof. Mayer is well known, both here and in Europe, as one of 

 the leading physicists, and Mr. Barnard is well known as a writer in all the leading 

 magazines, and as the author of a number of juvenile books.
