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 Obser- 

 vatory, 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 valu- 

 able, true scientific methods of thought, study, and work.
