tion of the ingredients it will be found in all cases that the 

 real proportions are in accordance with the calculated ones. 

 The left side of the curve has everywhere been drawn evenly 

 downwards. It may be taken for granted that w'herever the 

 lower limit for the size of the grains be placed, the quantity 

 must gradually decrease towards this limit. 



The left part of the curves has been divided into two areas 

 of which the upper indicates the quantity of clayey substance, 

 while the lower which is connected with the main part of the 

 curve, indicates the finer sandv ingredients. The ratio between 

 the two parts has been found by direct microscopic examination. 

 The ratio of the ingredients between 0"01 and 0-05°i°i can be 

 determined fairly correctly by counting the grains ; that of the 

 finest ingredients can only be conjectured, as we cannot disting- 

 uish clearly between grains of clay and grains of quartz in the 

 case of such very fine particles. 



The curves for the samples which are of special interest 

 will further be given below. 



The deposits No. 1 — 7 he, as will be seen from the chart, 

 in a series along the shore outside the Sabine and Кар 

 Bor läse Warren; we notice in these samples the very 

 pecuhar fact that the outermost ones, as shown by the curves 

 for No. 1 and 3, are far coarser than the innermost ones 

 represented by No. 4 and 7, to which also No. 5 and 6 bear a 

 very great resemblance. It has been mentioned above that 

 this fact is in contrast with the general rules by which the 

 fineness of the samples increases with the increasing distance 

 from shore and with the depth , and both distance and depth 

 are greater in the case of the first three samples. The di- 

 stance from shore is, however, too great for their coarser 

 ingredients to have been transported directly thence, so they 

 must have been derived either from icebergs or from the 

 bottom of the sea. 



That the dilîerence in the deposits should be due to ice-
