GLOBIGERINA OOZE: dirty white, slightly coherent, 

 granular. 

 CALCIUM CARBONATE (67-16 per cent.):— pelagic and 

 bottom-living Foraminifera, fragments of Echi- 

 noid spines, coccoliths and rhabdoliths. 

 RESIDUE (32-84 per cent-): — 



Siliceous Organisms [2 per cent.]; Radiolaria, 

 Diatoms, fragments of arenaceous Foramini- 

 fera. 

 Minerals [less than 1 percent.); mostly angular, 

 m.di. 0-08 mm., only one or two particles 

 of volcanic glass (?) observed. 

 Fine Washings [29-84 per cent.]; amorphous 

 clayey matter with minute fragments of 

 minerals. 

 Note: The sounding-tube brought up a roll about 



6 inches in length, apparently uniform throughout. 



-Michael Sars" Station 93. 25th July, 1910. 

 Lat. 50°13'N., Long. 11 23'W.-; Depth— 1257 m. (688 fms.). 



GLOBIGERINA OOZE: grayish colour, coherent, granular. 

 CALCIUM CARBONATE (53-16 per cent.):— pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 coccoliths and coccospheres, one or two rhab- 

 doliths. 

 RESIDUE (46-84 per cent.):— 



Siliceous Organisms [1 per cent.] ; Sponge spi- 

 cules, Radiolaria. 

 Minerals [10 per cent.]; angular and rounded, 

 m.di. 0-08 mm., appear to be all quartz 

 and mica. 

 Fine Washing [35-84 per cent.] ; amorphous 

 clayey matter with minute mineral particles. 

 Note: The sounding-tube brought up a roll about 



7 inches in length, apparently uniform throughout. 



"Michael Sars" Station 95. 26th July, 1910. 

 Lat. 50°22'N., Long. 11 -irw.; Depth -1797 m. (981 fms.). 



GLOBIGERINA OOZE: gray, coherent. 



CALCIUM CARBONATE (63-17 pet Cent.): — pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 Ostracods, coccoliths. 

 RESIDUE (36-83 per cent.): — 



Siliceous Organisms (1 percent.]; Sponge spi- 

 cules, Radiolaria, imperfect casts. 

 Minerals [2 percent.]; angular and rounded, 



m.di. 0-09 mm.; quartz, felspar. 

 Fine Washings [33-83 per cent.]; amorphous 

 clayey matter with minute mineral particles. 



Note: The sounding-tube brought up a roll about 

 9 inches in length. From this station Dr. Peach records 

 over two hundred rock fragments, distributed probably 

 by natural agencies, as well as a large quantity of furnace- 

 slag, pieces of pottery, and the cannon bone of an ox, 

 probably thrown overboard from ships. Among the sedi- 

 mentary rock fragments are greywacke, sandstone, shale, 

 lydian-stone, quartzite, limestone, calcareous shale, chalk, 

 chalk-flint, dolomite, and vein quartz; of metamorphic 

 rocks there are gneiss, schist, slate, phyllite, felsite and 

 epidiorite; igneous rocks include granite, nepheline syenite, 

 lamprophyre, dolerite, and basalt. 



"Michael Sars" Station 98. 5th August, 1910. 

 Lat. 56°33'N., Long. 9''30'W.; Depth— 1360 in. (742 fms.), 



GLOBIGERINA OOZE: darkish gray, granular, slightly 

 coherent. 

 CALCIUM CARBONATE (40-73 pet Cent.): — pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 coccoliths and coccospheres. 

 RESIDUE (59-27 per cent.):— 



Siliceous Organisms [1 per cent.]; Sponge spic- 

 ules, imperfect casts. 

 Minerals [30 per cent.], mostly rounded, m.di. 

 01 mm.; almost entirely quartz and mica, 

 no other species being determinable. 

 Fine Washings [28-27 per cent.]; amorphous 

 clayey matter with minute mineral particles. 

 Note: Only a very small sample was available from 

 this Station.
