rainfall, weather, and climate receive careful consideration. The text is illustrated by many maps and diagrams, of which a number are original. The generalized charts, showing the winds of the Atlantic and Indian Oceans, taken from the atlas of the German Naval Observatory, are particularly valuable. But a few of the diagrams, although showing clearly what they were intended to represent, fall short of the standard of artistic excellence set by the others.

The value of this book lies, if in some things more than in others, in the logical treatment of the subjects, the frequent turning aside from the discussion for the purpose of introducing additional facts in order to correct, modify or substantiate hypotheses, and the clear discrimination, between facts, well-established theories, and working hypotheses. The pupil, who uses this book intelligently, will learn, not only many things about meteorology, but what is far more valuable, true scientific methods of thought, study, and work.
