coarser consistency, the maximum size of the ingredients being 

 between 0"05 and O'ô"™. This is most easily explained by the 

 fact that the lesser depth of deposition viz. 112 and 150 Danish 

 fathoms respectively* may produce a current which is strong 

 intermittently, and which will prevent the finer ingredients from 

 being deposited, whereas at other times other circumstances 

 may prevail. Though most of the material in the samples is 

 of a somewhat variable nature, we must yet suppose that it 

 originates for the most part directly from land. The coarsest 

 ingredients on the other hand seem to form a strongly marked 

 separate maximum to the right of the curve. These ingredients 

 are of a very different nature in the two samples. No. 31 con- 

 taining a mixture of granitic material and sediments , while 

 No. 32 contains only the former. This might indicate that the 

 material for the most part has its origin in rocks at the bottom 

 of the sea, at any rate it is unlikely that icebergs would be 

 able to deposit material of such a different nature in adjacent 

 places. At the same time part at least of the coarser material 

 may originate from moraines at the bottom of the sea. The 

 influence of this factor is, however, very difficult to account 

 for here, as also in several of the other samples. 



Sample No. 33 was obtained from very near the shore out- 

 side Кар Hodgson, and at a very small depth viz. 88 D. fa- 

 thoms. We should therefore expect the sample to be of a very 

 coarse consistency as is clearly shown by the curve to be the 

 case. This curve breaks up very conspicuously into two parts, 

 the left part somewhat flattened with maximum at about Vso"'^, 

 and a very steep part on the right with maximum between 8 and 

 16mm Possibly this last maximum ought to be placed even 

 farther to the right, as ingredients of over 16™"^ very rarely 

 enter into the samples. 



The finer part of the sample originates for the most 

 [»art directly from land. The small quantity of the ingredients 

 under О-О!'""' is partly due to the proximity of the shore, which
