" The author has done good service to the glaciologist and glacial geologist 

 in bringing together his concise description and classification of existing 

 glaciers and ice-sheets in the present convenient form. Especially in the 

 parts devoted to Arctic and Antarctic ice he has made an exhaustive digest 

 of the scattered literature, and has presented a copiously illustrated summary 

 of the available information respecting the distribution and character of 

 the ice of these regions. To the end of each chapter he appends a full list 

 of his authorities, so that the book is in every respect a most useful work 

 of reference. . . . Every geographer and geologist interested in ice will 

 appreciate these clear descriptions and excellent illustrations of the earth's 

 great glaciers they make up into a most presentable book." Nature.
