Samples Nos. 4 — 7, which were obtained immediately on 

 the inland side of the preceding ones, show a quite different 

 constitution. If we leave out of consideration 8 pieces of clay 

 in No. 5, which may perhaps have been hardened at the bottom 

 of the sea, only 9 rock-fragments altogether are found in the 

 4 samples ; of these only one is granite, while 6 are sediments 

 and 2 basalt. Most of these must be supposed to have been 

 conveyed hither by icebergs. The proportionately large quantity 

 of sediments is somewhat remarkable. 



Samples Nos. 9 — 13 are, as above mentioned, some of the 

 coarsest of all, and contain a great number of fragments which 

 must be supposed to have originated from the moraine. The 

 composition also shows a certain analogy with that of the 

 three first samples, as 29 fragments out of 92, or about a 

 third part consists of granitic material. They also contain 

 fragments of 34 sediments, half of which are quartzite or hard 

 sandstone, the greater part of these originating from the De- 

 vonian ; 6 are loose sandstone, and 1 1 slate. These samples 

 differ, however, from the first in containing a large amount of 

 basalt, 29 fragments in all, this being due to the wide distribu- 

 tion of basalt in the country inland from Кар Broer Ruys. 



In samples 14 — 19 very small quantities of rock-fragments 

 are found, so that we can hardly draw any decided conclusion 

 from the ratio between them. Altogether in the 6 samples 

 there are 11 fragments, where of 4 are gneiss or granite, 

 6 sediments, and 1 basalt. These must presumably have been 

 derived from icebergs. They also show a somewhat similar 

 ratio in their rock-fragments as was seen in the samples 4 — 7, 

 the only difference being that these contain a somewhat smaller 

 amount of granite. The one bivalve found in sample 18 must 

 also have been derived from the ice, as it was found at a far 

 greater depth than that at which it could originally have lived. 



Sample No. 22 shows an equal mixture of the different 

 ingredients and here, as before mentioned, we must imagine
