Abstract
ALTHOUGH no land débris of any kind was observed by us on the icebergs, there cannot be the slightest doubt that such is carried by them all over the region and distributed on the bottom. The samples brought up by the sounding instrument consist almost entirely of comminuted clays and sands, and the dredge always contained in considerable quantity, about the meridian of 80° E., chiefly basaltic pebbles, and, further to the eastward, pebbles and larger fragments of metamorphic rocks, granite, gneiss, mica-slate, hornblende-slate, clay-slate, and chlorite-slate.
