here, iu comparison with that wiiicli they exercise on most of 

 tlie other samples. As far as we l^now, this particular tract is 

 rather free from ice in summer, so that proportionately few 

 icebergs would melt here. We are then obliged to suppose, 

 that the above-mentioned moraine bends inwards along this 

 tract, which may perhaps be explained by the high coast lying 

 inside it. It is strange that deposits from the land or from 

 the ice have not completely covered this moraine since the ice- 

 age, but no other explanation is probable. 



The complicated shape of the curves with respect to the 

 -i samples is thus connected with the fact that one part of the 

 sample originates from the original moraine — or stratified 

 material from the ice-age, the other and finer part, on the 

 other hand, from material conveyed hither at a later period. 



No. 9 is the most regular of all the samples. We cannot 

 imagine a better illustration of a sample consisting of two quite 

 different parts. The remarkable height of the curve between 

 8 and 16"*™, and the great slope towards both sides, indicates 

 that originally a gravel with grains of an unusually uniform 

 size was deposited in this locality. After the ice-age finer 

 material was deposited here, partly by transport from land, partly 

 by icebergs , this being also of a rather regular constitution, 

 with maximum between V32 and ^/б4^^. This material must 

 have been laid down among the coarser ingredients, or has at 

 any rate become mixed with them during the hauling up. 



The three following samples Nr. 10 — 11 and 13, are far 

 more difficult to account for. It seems as if the originally- 

 deposited rock , in these cases was in itself of a rather 

 irregular constitution. If we draw up curves for morainic 

 rocks we always get a rather irregular figure with more maxima, 

 and this is especially the case with such rocks in mountainous 

 parts. It will be impossible to determine with regard to these 

 samples how great a part emanates from later deposits. Prob- 

 ably however at least half of the finer ingredients was thus
