" The object of the volume is to present the leading phenomena of Sound in a 

 simple and entertaining manner, by the use of such materials as are almost every- 

 where at hand, and with apparatus which any ingenious student can construct 

 for himself. To present the elements of an abstruse subject in such a way as to 

 make the exposition easily comprehensible by a mind not specially trained in 

 it, and at the same time correct and satisfactory from a scientific point of view, 

 is one of the most difficult undertakings in the work of an instructor. Add to 

 this the task of bringing the experimental illustration of a science like that of 

 acoustics, which requires such refinement in the apparatus and its manipulation, 

 within the resources of every one, and we have the difficulty very greatly in- 

 creased. Professor Mayer's well-known experimental skill has enabled him to 

 accomplish the work in an admirable manner, and he has laid under obligation 

 to him not only the student and the amateur experimenter, but the teacher, who 

 will derive many valuable suggestions as to his own work from this little volume. 

 The subject is arranged in a very clear and methodical manner, and treated in a 

 vivacious and entertaining style. The experiments, many of which are novel, 

 unite extreme simplicity with elegance of conception and scientific precision, 

 and can not fail to interest and stimulate the minds of the students into whose 

 hands the volume may fall. The illustrations, which are numerous, are ex- 

 cellently done, and give the book a very attractive appearance. 11 American Jour- 

 nal of Science and Arts. 



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

 mate adaptation to its modest end, of this little treatise on 4 Sound.' 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 pro- 

 gressive order. The recent inventions of the phonograph and microphone lend 

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

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