2 g THE DEPOSITS OF THE SEA-BOTTOM. 



dicate a granulite-like rock; further some pieces of a black rock, possibly basalt; a few 

 grains of feldspar. 



Station 32. West of Greenland; Gray deep-sea clay; 1-15 per ct. Chiefly grains of quartz; further 

 were found some pieces of clay-slate, phyllite, biotite-schist, sandstone, and gneiss; a few 

 grains of feldspar. 



Station 33. West of Greenland; Sand; 0-64 per ct. About six seventh of the specimen grains of quartz; 

 the rest feldspar, perhaps a single piece of gneiss; some few indeterminable gray grains. 



Station 34. West of Greenland; Sand; 2-95 per ct. Far the greater part grains of quartz; further 

 feldspar, biotite, muscovite-schist, pieces of gneiss or granite; several indeterminable pieces. 



Station 45. West of the Faroe Islands; Globigerina clay; 1-84 per ct Chiefly not volcanic, being 

 mostly grains of quartz; besides feldspar, a single piece of sandstone; of volcanic material 

 was found black, compact or more or less porous basalt. 



Station 46. West of the Faroe Islands, southeast of Iceland; Transition clay; 7-64 per ct. The grains 

 rather rounded, reddish brown on the surface. Far the greater part not volcanic; in the 

 first instance an immense mass of grains of quartz; next sandstones some of which of a 

 very peculiar nature, consisting besides grains of quartz of a compound of brown, white, 

 and black grains; further mica-schist, clay-slate, and rocks of a gneiss- or granulite-like 

 nature; finally grains of orthoclase, plagioclase, and biotite; of volcanic material was found 

 a number of pieces of basalt, some of them more porous. 



Station 47. Southeast of Iceland; Globigerina clay; 1-31 per ct. The larger pieces almost angular. 

 Far the greater part not volcanic material, especially a large mass of quartz; besides grayish 

 sandstone, biotite, muscovite, and feldspar. Of volcanic material was found compact basalt, 

 black, vesicular glass, tufa; further augite and magnetite. 



Station 48. Southeast of Iceland; Globigerina clay; o - oi per ct. Chiefly not volcanic; of 12 small 

 grains 6 were quartz, 2 feldspar with a dark mineral; of volcanic material were found 2 

 grains of black, compact basalt, 1 of porous basalt, 1 of magnetite. 



Station 50. Southeast of Iceland; Transition clay; the percentage undetermined, rather small. Almost 

 exclusively volcanic material, that is to say basalt, partly compact, partly glassy, porous; several 

 pieces that were not to be defined, on account of their smallness. One single grain of quartz. 



Station 54. Southeast of Iceland; Transition clay; 14-26 per ct. Most of the grains rounded, disinte- 

 grated on the surface, sometimes with a brownish crust The large number of grains al- 

 most exclusively of volcanic material viz. primarily a black or dark gray, fine-grained basalt 

 forming all the larger pieces; further compact basalt; black, porous, volcanic glass, brownish 

 feldspar, obsidian, tufa. Of other ingredients were found some grains of quartz. 



Station 58. East of Iceland; Gray deep-sea clay; 0-05 per ct All the grains very small, chiefly com- 

 pact, grayish or black basalt; further black, porous glass. Of not volcanic material a number 

 of grains of quartz were found. 



Station 59. East of Iceland; Gray deep-sea clay; o-oi per ct. Only few and very small grains, chiefly 

 basalt; black, volcanic glass and tufa; a few grains of quartz and feldspar.
