"Professor Mayer has invented a series of experiments in Light which are 

 described by Mr. Barnard. Nothing is more necessary for sound-teaching than 

 experiments made by the pupil, and this book, by considering the difficulty of 

 costly apparatus, has rendered an important service to teacher and student alike. 

 It deals with the sources of li-jht, reflection, refraction, and decomposition of 

 light. The experiments are extremely simple and well suited to young people." 

 Westminster Review. 



"This work describes, in simple language, a number of experiments illus- 

 trating the principal properties of li;_ r ht, by means of a beam of sunlight admitted 

 into a dark room, and various contrivance*. The experiments are highly in- 

 genious, and the young student can not fail to learn a great deal from the book. 

 As an example of the effective experimental method employed, we may specially 

 mention the device for illustrating the refraction or light. This book is specially 

 designed ' to give to every teacher and scholar the knowledge of (he art of experi- 

 menting.' " The Quarterly Journal of Science (London). 



"A singularly excellent little hand-book for the use of teachers, parents, and 

 children. The book is admirable both in design and execution. The experi- 

 ments for which it provides are so simple that an intelligent boy or girl can 

 easily make them, and so beautiful and interesting that even the youngest chil- 

 dren must enjoy the exhibition. The experiments here described are abundantly 

 worth all that they cost in money and time in any family where there are boys 

 and girls to be entertained." New York Evening Post. 



" The experiments are capitally selected, and equally as well described. The 

 book is conspicuously free from the multiplicity of confusing directions with 

 which works of the kind too often abound. There is an abundance of excellent 

 illustrations." New York Scientific Ameiican. 



"The experiments are for the most part new. and have the merit, of com- 

 bining precision in the methods with extreme simplicity and elegance of design. 

 The value of the book is further enhanced by the numerous carefally-drawfi cuts, 

 which add greatly to its beauty." American Journal of Science and Arts.
