these ingredients are not present in far larger quantities. The 

 main mass of the sample is also somewhat coarser than the 

 last-named with maximum at about Veé^^^. This is in agree- 

 ment with the fact that the sample was found in closer proxi- 

 mity to land, but also nearer the open sea. 



No. 46, which came from the mouth of Hurry Inlet, 

 without any closer indication of the locality, resembles the last- 

 named sample in the small amount of its ingredients between 

 V20 and 4™™. This sample contains the largest amount of 

 the ingredients under 0"01°i°i viz. 90*1 per Gt. The curve is an 

 exceedingly regular and symmetrical figure, with the exception 

 of the small quantity of material over 0'05°i°^ which was 

 derived probably from the ice. The regular shape indicates a 

 uniform and regular conveyance of the ingredients. The colour 

 of the sample is very characteristic compared with that of the 

 others, as it is of a very pronounced reddish-brown colour. 

 This is probably in some way connected with its fineness as 

 the two last-named samples were also of a brownish colour; 

 but no real explanation of the difference in colour has been 

 given as yet. 



The preceding pages will have shown that the various 

 samples differ greatly in their mechanical constitution. These 

 variations- are often very conspicuous , especially when they 

 occur in the case of two adjacent samples which we should 

 have imagined would be alike in everything. There can scar- 

 cely be many parts of the world where such great contrasts 

 are seen between adjacent deposits at the bottom of the sea. 

 In most cases therefore it will be very difficult to account 

 for the natural conditions which have determined the deposi- 

 tion of each deposit, moreover the various factors which must 

 be taken into consideration are only somewhat imperfectly 

 known. It is possible from the constitution of the samples to
