points of intermediate height from the littoral regions, and finally 

 the numerous almost equal altitudes showing the higher topography. 

 From the distribution of the points it may be ascertained whether a 

 locaHty is high or low, but we learn nothing about the various 

 erosion forms, such as the rounded formations due to the action of 

 the inland ice or the alpine formations caused by the local glaciers. 

 In nature the latter always seem higher than the former. By 

 connecting the highest points, a fine zigzag line will appear, showing 



the average elevation of 

 the peaks. In this I suc- 

 ceeded in constructing 

 the two profiles. Figures 

 I and 2, for the west 

 and east coast, respect- 

 ively. These, however, 

 call for a more detailed 

 explanation : 



The west coast profile 

 (Fig. i). — It will be seen 

 at once that the district 

 of Frederikshaab seems 

 to be remarkably low, 

 a single peak, however, 

 rising to the height of 

 the surrounding areas. 

 This appearance s not 

 due to the district being 

 low in fact, but is caused 

 by the defects of the map, as practically only the skerries are 

 charted. From a ship at some distance from land it is plainly seen 

 that the whole district is high, of the same elevation as the areas 

 to the north and south of it. Moreover, there are a number of 

 peaks near Holsteinsborg which rise above their surroundings and 

 show plainly in the profile. These peaks, however, consist of iron 

 gneiss, they are found only near the coast, and the regions behind 

 them are much lower. Special petrographic conditions have been 

 united to form an isolated high area, which must not be taken into
