conditions. Conversely, the epoch is regarded as primarily due 

 to elevations, now measurable, with the consequent deflection of 

 the Gulf Stream. Even where some are indisposed to accept this 

 conclusion as to the cause of the Glacial Period, no other expla- 

 nation of the origin of these submarine channels has been shown 

 to obtain, Avhich interpretation has been given to them in this 

 country by Dana, Chester, Lindenkohl, Davidson, Branner, 

 Upham, and the reviewer, all who have investigated the prob- 

 lems at first hand. 



The data, shown in graphic form, are indispensable, both the 

 physiographic as well as the oceanographic, and the whole 

 constitutes a worthy monument of the labors of the author, 

 which must be lasting so long as interest in the Earth's studies 

 lasts. These studies had been almost passed over by the earlier 

 oceanographic writers, but they are so widespread that their 

 study constitutes a new brand of science, which Hull most gener- 

 ously attributes to the reviewer as the founder, by his work 

 on the Antillean region and off the American Coast. j. w. s.
