he has set forth the subject with great clearness and beauty. His exhibi' 

 tion of the storms of the Southern hemisphere is full and satisfactory, and 

 entirely accordant with Mr. R.'s published statements. As Americans, 

 we can not but feel much gratified with the frankness with which he 

 attributes to our countryman the credit of establishing the true system, on

 where honor is due, are creditable alike to the head and heart of its author. 

 The volume deserves attentive study ; as the matters of which it treats,-, 

 and the results which it presents, are not only interesting to the theoreti- 

 cal philosopher, but also of immense importance to all who expose their 

 lives or their fortunes to the perils of the ocean.
