largely dependent on other circumstances, which are not directly 

 connected with the depth. A brief survey of the above table 

 will show us, that there is no very direct connection between 

 the nature of the deposit and the depth of its formation. As 

 a rule it may be said that all the samples which contain the 

 largest amount of clay were obtained from a greater depth than 

 a hundred Danish fathoms, and thus may deserve the designa- 

 tion of grey deep-sea clay, but that the greater part of the 

 samples which contain a large proportion of sand and clay are 

 from very varying depths. 



The character of the samples depends not only on the depth 

 from which they are procured, for the greater or lesser distance 

 from the shore at which they have been formed also exercises an 

 influence on their composition. Generally these two influences 

 go pretty much together, so that it is not easy to make sure 

 whether one or the other plays the more prominent part, but 

 in many cases it is possible to see the direct effect of one of 

 these influences. It is thus fairly evident that the greater 

 number of samples from 14 — 22 are almost pure clays owing 

 to their having been obtained so much farther from the shore 

 than the other samples. The influence of the depth is seen 

 still more distinctly in some individual cases. Thus sample 

 No. 30, which was taken from the immediate neighbourhood of 

 the shore, is very fine-grained in comparison with its neighbours 

 and is consequently from a much greater depth. 



That the depth and the distance from shore combined are 

 not always sufficient to determine the general nature of the 

 deposits is proved in a very striking manner by samples 

 No. 1 — 7, which were taken in a continuous line at right angles 

 to the coast-direction. Here both the depth and the distance 

 from shore decrease from Nr. 1 to 7, and in spite of this, the 

 samples are rather finer at the beginning of the series. From 

 this we may certainly conclude, that the greater number of the 

 coarser ingredients in the samples cannot have been transported
