"We know of no book written with a set purpose better adapted to serve the 

 purpose for which it was written, nor any that the earnest student of optics will find 

 more interesting and profitable. The work itself, without the confession of the preface, 

 shows that Professor Schuster is a teacher, and every page bears evidence that he is a 

 master of his subject. . . . We heartily recommend the book to our readers."
