The Ocean of Air. By A. Giberne. (Seeley and Co.)—Miss

Giberne in " Sun, Moon, and Stars " showed that she could pre- sent astronomy to her readers in a pleasant and chatty form. In The Ocean of Air we find the same ease in plating physical laws into ordinary and non-technical language. It is true that in doing so a writer has often to make statements of a somewhat general nature. But, with a few exceptions, Miss Giberne hits the mean between painful accuracy and too much breadth with sufficient skill. And we can be sure that none of Nature's laws lose their beauty or significance in her hands. Young people will find it interesting and the very reverse of dull. They have, in- deed, few books so really instructive as this should prove. The illustrations are capitally reproduced photographs, and amongst them are some really beautiful pictures of clouds, mists, lightning- flashes, and frozen torrents.
