Mud/and. By the Rev. W. Clement Ley. (E. Stanford.)— This

" study on the structure and characters of clouds" will be found full of interest. The subject is comparatively new ; at least, we do not remember to have seen it treated in such detail and with so much care as are exhibited in this volume. We can- not pretend to follow Mr. Ley in his discussion of the subject, but we may commend his volume to the notice of all who are interested in meteorology. It is a contribution of distinct value to a science of which the development is disappointingly slow and uncertain.
