PRESS NOTICES.

"A most fascinating volume, treating of phenomena in which all are interested, in a delightful style and with wonderful clearness. For lightness of touch and yet solid value of information the chapter 'Why Has Man Two Eyes?' has scarcely a rival in the whole realm of popular scientific writing."—The Boston Traveller.
