same region reveals the extent and importance of the changes, 
which are so great as to make it apparent that the new map is 
really such, and not merely a corrected copy of the old. The 
modifications are so extensive that, were it not for the names, 
the new map and the last edition of the chart of the same region, 
issued by the Hydrographic Office, would hardly be taken to 
represent the same coast. In some places the general trend of 
the coast is altered many degrees. Many bays are mapped 
which have not hitherto found representation, and many inden- 
tations of the coast which have heretofore appeared on the 
charts, have been changed in position and size. Eleven islands 
which do not appear on the published charts referred to have 
been accurately located, and the position, shape and size of those 
heretofore represented have been corrected. A large number of 
glaciers, probably as many as 100, have been located with 
approximate accuracy, within the region where but ten were 
represented on the published chart referred to, and even these were 
in some cases in false positions and greatly exaggerated in size. 
Astrup’s map of Melville Bay, already published, should be men- 
tioned in this connection, since it was prepared while its author 
was a member of Mr. Peary’s corps. Geographers will not fail 
to appreciate the magnitude and the importance of this carto- 
graphic work. 
In addition to the map, Mr. Peary has kept a series of 
meteorological records, probably the most accurate and elabor- 
ate which have ever been secured in so high a latitude. Besides 
the more formal records, he has been observant of the behavior 
of winds about the ice-sheet, and in this way has come into pos- 
session of facts which are not without significance in connection 
with the problems of glaciology. He has made careful measures 
ments of the rate of motion of one of the most active glaciers of 
the region, and has carried them through a sufficiently long 
period of time to give them especial value. He has brought 
back two large and choice meteorites from the coast east of 
Cape York, the study of which will possess much popular as well 
as scientific interest. 
In quite another line important studies have been prosecuted
