expedition, a fact which does not prove the Icelandic basalt 

 to be of another nature than the Greenland one, but merely 

 admits that in most of the Icelandic samples an unusually 

 large amount of volcanic glass is found, which has probably 

 fallen down as ash for the most part, and this changes the 

 percentage of the augite. 



In the sample No. 42, were found 5 basaltic stones out of 

 9, thus about 55 per Ct., while the amount of augite in the 

 sand is 35 per Ct. In the three last samples (Nos. 43 — 46) no 

 fragmental ingredients are found, so that it may be possible, 

 from the amount of augite, to form a judgment of the part 

 which the basalt has played in the formalion of these deposits. 

 No. 43, which is situated in Fleming Inlet, has 4 per Ct. 

 of augite; we should thus expect that about 10 per Ct. of the 

 ingredients of the sample were of basaltic origin, probably 

 originating from the country near Кар Moorsom. No. 45, 

 situated in Carlsberg Fjord, has 9 per Ct. of augite, but 

 probably only a part of it originates from the basalt, while the 

 rest must come from the above-mentioned rocks at the Liver- 

 pool Kyst. The same is probably the case with the augite 

 in No. 46, obtained from Hurry Inlet. 



The olivine is found everywhere in smaller quantities than 

 the augite, and generally stands in a certain relation to it with 

 regard to amount, wherefore it is of no special interest. 



Rutile, Zircon and Tourmaline, are, as might be expected, 

 only found in very small quantities in the sand, and the same 

 is the case with the mica which is even strikingly sparsely 

 represented. 



Nor is garnet present in very great amounts in any of the 

 samples at the highest the percentage is 6, while in a single of 

 the West-Greenland samples from the Ingolfexpedition it was 17, 

 and in the next East-Greenland one taken near Angmagsalik, 

 it was 9,5 per Ct. A large amount of garnet in the samples 

 generally indicates that these for a great part must have their
