" It would be difficult to find a better example of a pcries which is excellent 

 throughout. This little work is accurate in detail, popular in style, and lucid in 

 arrangement. Every statement is accompanied with ample illustrations. We 

 can heartily recommend it, either as an introduction to the subject or as a satis- 

 factory manual for those who have no time for perusing a larger work. It con- 

 tains an excellent description, with diagrams, of Faber's Talking Machine and 

 of Edison's Talking Phonograph, which can not fail to be interesting to any 

 reader who takes an interest in the marvelous progress of natural science." 

 British Quarterly. 



" The style of the book is very clear, and the experiments interesting. It can 

 not fail to have an important educational influence." Westminster Renew. 



"It would really be difficult to exaggerate the merit, in the sense of consum- 

 mate adaptation to its modest end, of this little treatise on ' Sound. 1 It teaches 

 the youthful student how to make experiments for himself, without the help of 

 a trained operator, and at very little expense. These hand-books of Professor 

 Mayer should be in the hands of every teacher of the young." New York Sun. 



"An admirably clear and interesting collection of experiments, described 

 with just the right amount of abstract information and no more, and placed in 

 progressive order. The recent inventions of the phonograph and microphone 

 lend an extraordinary interest to this whole field of experiment, which makes 

 Professor Mayer's manual especially opportune." Boston Courier.
