Mr. Bailey is one of the leading geniuses among American school men in the art of teaching physics with inexpensive apparatus and without laboratory equipment, making the study at once attractive and instructive. Any teacher of ordinary sense and a little tact can easily teach elementary physics in the upper grammar grade by the use of this book. The book is not only commended, but those who desire to teach physics in elementary schools or are expected to teach the subject are urged to examine the book and see for themselves how clear and simple instruction is made. —American Primary Teacher, Volumes 15 [1897]
