598 The American Naturalist. [July, 
American glaciers, besides giving brief descriptions of glacial phenomena 
in general. The closing chapter presents a view of the life history of an 
alpine glacier, of which representatives occur in abundance and in great 
variety in North America. The author instances the Seward glacier, 
Alaska, as the largest of this type that has ever been discovered. 
The Malaspina glacier, the great ice sheet which intervenes between 
Mt. St. Elias and the Pacific, represents a second or Piedmont type, and 
the still larger, or Continental glacier, is typified by a single example 
in Greenland. 
The work is abundantly illustrated by maps, page plate pictures re- 
produced from photographs, and cuts in the text.
