3. Geographical Distribution of Greenlandic Mammalia. 



Similarity of physical contour, and a general uniformity of 

 climate, varying no doubt in degree, but still sufficiently inhos- 

 pitable throughout, with an abundance of the food on which all of 

 them subsist throughout the habitable tracks and in the sea wash- 

 ing the shores of Greenland, have failed, contrary to what might 

 have been expected, to produce a geographical distribution of the 

 Mammalia in a like universal manner, or at all corresponding to 

 the physical uniformity hinted at. It is only in the sea and on a 

 narrow strip of land skirting the shores of Greenland that animal 

 life has yet been found. The whole interior of the country appears 

 to be merely a frozen waste, overlain to a depth of many feet by a 

 huge mer de glace, extending, so far as yet known, over its entire 

 extent (with the exception of the strip named) from north to south 

 ■ — a sea of freshwater ice whereon no creature lives, a death-like 

 desert with nought to relieve the eye, its silence enlivened by the 

 sound or sight of no breathing thing. This is the Inlands lis of the 

 Danish colonists ; the outer strip, with its mossy valleys and ice- 

 planed hills, is the well-remembered Fastland. Dreary, doubtless
