Phenomena of Light, for the Use of Students of Every Age._

"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 light, 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
illustrating the principal properties of light, by means of a beam of
sunlight admitted into a dark room, and various contrivances. The
experiments are highly ingenious, 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 of light. This book is specially designed
'to give to every teacher and scholar the knowledge of the art of
experimenting.'"--_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 experiments 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 children 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 American._

"The experiments are for the most part new, and have the merit of
combining precision in the methods with extreme simplicity and
elegance of design. The value of the book is further enhanced by the
numerous carefully-drawn cuts, which add greatly to its
beauty."--_American Journal of Science and Arts._
