Light : a Course of Experimental Optics. By Lewis Wright.

(Macmillan and Co.)—The main characteristic of this well-written and amply illustrated handbook is its practicalness. Science teachers who are determined to teach optics as they should be taught ought to welcome this book cordially. It is original in method and material. The explanations of the phenomena of light here described are as full, as clear, and as precise as are the instructions for the making and using of the apparatus needed for their demonstration to a class. This book, moreover, can be read, used, and, we may add, enjoyed, by those students of optical phencimena who are not conversant with mathematics.
