grain Nvliicli is found in the greatest numbers in these samples 

 has time to be deposited, while the coarser ingredients sink to 

 the bottom nearer land, and the finer ones are transported 

 still farther away. If the currents change in direction and 

 force, it will be seen that several ditferenl sizes of grains 

 will appear in the samples , and thereby the curve will 

 become broader and lower. Something like this is the case 

 witii sample No. 18, but as it is situated between two others 

 the difference between them is quite inexplicable, and likewise 

 the circumstance that in No. 18 is found a number of the coars- 

 est ingredients. This phenomenon can hardly be explained 

 otherwise than as a mere accident. 



Sample No. 22 shows , as is seen by the curve , the same 

 phenomenon as so many of the former samples , viz. that 

 it consists of two rather well-separated parts , viz. a smaller 

 one with the maximum between 2 and i^"^ and a larger one 

 with maximum at about Vioo^^"^. As it is not {згоЬаЫе that 

 the above-mentioned moraine comes so close to the shore, we 

 may suppose that the comparatively great amount of coarser 

 ingredients is due to icebergs, or possibly the two causes may 

 be acting in concert. The nature of these coarser ingredients 

 is rather mixed, and cannot explain anything for certain either 

 one way or the other. 



Sample No. 24, situated outside the mouth of Davys Sund, 

 is of a very fine-grained nature. The curve has a very regular 

 and symmetrical form with maximum between Vrjs and Voae™™, 

 and there is a comparatively large amount of clay-substance. 

 The most characteristic feature in the sample is, however, the very 

 small amount of larger ingredients, as it only contains 0*3 per Ct. 

 over ООо""™, which is less than in any of the other samples, 

 much less even than in any of the samples from the Ingolf- 

 Expedition, which are on the whole considerably finer than 

 the ones described here, and a great number of which were 

 obtained in deep water at a great distance from land. The
