western coast of Greenland, from an insular climate to the littoral 
climate of the western Polar archipelago, which latter, as we have 
seen, assumes itself a continental character. While the figure 90 may 
be taken as expressive of the Siberian continental climate, 02 is found 
for the North American Polar islands, and 45 for the western coast of 
South Greenland. This latter value is of course produced by the 
vicinity of the Atlantic Ocean. The high figures 62G and 00*7 for 
Rensselaer and Wostenhulm, point most conclusively to either a con¬ 
siderable northern expanse of Grinnell Land on one side and an eastern 
extent of Washington Land on the other, or to a considerable elevation 
of the interior on both sides of the channel above its level. Roth 
suppositions are supported by the highlands seen from the northernmost 
station reached, and by the location of a stupendous glacier, which, as 
is well known, requires extensive and elevated snow-areas as feeding- 
reservoirs. The above conclusion appears to be in opposition to the 
presence of water open to navigation; but the explanation offered can 
be reconciled with facts by supposing an unobstructed and broad con¬ 
nection of Kennedy Channel with the great Polar basin.
