The topography is taken from the chart accompanying the 

 Admiralty correspondence connected with the British arctic 

 expedition of 1875. The geological boundaries of Parry Islands 

 and the north coast of America from the determinations by 

 Conybeare, Murchison, Salter, and Haughton of the specimens 

 brought back by the expeditions of Franklin, Parry, Back, John 

 and James Ross, Sabine, Buchan, Beechsy, Sherard Osborn, and 

 McClintock. Those of West Greenland from the observations of 

 Giesecke, Nordenskiold, O'Heer, and Brown. Those of East 

 Greenland and Spitsbergen from the results of the various 

 Austrian, Swedish, and North German expeditions. Those of 

 Hall Basin, and the channels lying north of Smith's Sound, from 

 the labours of Kane and Bessels, which prove that the upper 

 Silurian rocks, noticeable along the southern fringe of the Arctic 

 archipelago reappear in this tract, the Lower Carboniferous coal- 

 bearing sandstones and overlying Carboniferous Limestones lying 

 in a basin.
