"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 everywhere 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 com- 

 prehensible by a mind not specially trained in it, and at the same time correct and satis- 

 factory 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 

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

 plish 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 ex- 

 periments, 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 stu- 

 dents into whose hands the volume may fall. The illustrations, which are numerous, are 

 excellently done, and give the book a very attractive appearance." American Journal of 

 Science and Arts. 



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

 tion to its modest end, of this little treatise on ' 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 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."
