How to Use our Eyes. By John Browning. (Chatto and

Windus ) —We do not remember to have seen this little volume before, though it bears on its title-page, "fourth edition, seventh thousand." That is a fact which is more to the point than any criticism of ours could well be. We may say, however, that the success of the book seems thoroughly well deserved. There is an amazing amount of ignorance about the sight. One of the commonest delusions is that it is well to put off the use of sp3ctacles as long as possible. As a matter of fact, nothing could be more injurious. Most people who begin life with average powers of vision find them begin to fail before they reach fifty. They should seek aid the very first moment that they find themselves altering the focus of what they read to suit their eyes. This is, of course, only one of the common errors and mistakes. Mr. Browning deals in a simple, intelligible fashion with the subject. This is a most useful volume.
