(50 '00 %), Radiolaria, Astrorhi- 
zidse, Lituolidae, numerous 
Piatoms. 
(15'00 %), m. di. O'lO mm., 
angular ; quartz sometimes 
coloured red, monoclinic and 
triclinic felspars, mica, horn- 
blende, tourmaline, garnet, 
magnetite, zircon, glassy vol- 
canic particles, glauconite. 
(12'53 %), a little amorphous 
matter, a few mineral 
particles, but principally 
fragments of Diatoms. 
The trawl came up fouled, but contained a few animals 
and pebbles, the latter varying in diameter from 5 mm. 
to 1 cm. ; one of the pebbles is a granitite, containing 
quartz, plagioclase, orthoclase, hornblende, black or 
green mica ; another is a fine-grained chloritic sandstone 
with felspar. The minerals, as well as the rock frag- 
ments obtained at this station, appear to indicate that 
they come from rocks belonging to older formations. 
(15 ’00 %), Eadiolaria, Sponge 
spicules, Astrorhizidae, Lituo- 
lidsB, Diatoms. 
(20'00 %), m. di. O'lO mm., 
angular ; quartz, felspar, 
plagioclase, hornblende, glau- 
oonite, garnet. 
(61 '50 %), amorphous matter, 
minute fragments of minerals 
and Diatoms. 
The dredge brought up many rocks and pebbles, to which 
an Ascidian and an Actinian were attached, and a few 
animals. The quartz grains are sometimes rounded and 
covered with limonite. Among the pebbles are granitic 
rooks, containing orthoclase, plagioclase, quartz, and 
black mica ; amjihibolite with large grains of green 
hornblende and quartz ; metamorphic quartzite speckled 
with black mica ; fine grained micaceous sandstone 
passing to a schist; and red sandstone. 
(3 "00 %), Radiolaria, Sponge 
spicules, Diatoms. 
(20'00 %), m. di. O'lO mm., 
angular; quartz, felspar, horn- 
blende, mica, epidote, garnet, 
glauconite. 
(76 '00 %), amorphous matter, 
fine mineral particles and 
Diatom remains. 
Some particles of ^(inerals attain a diameter of 1 or 2 
mm. ( 
(3 ’00 %), Radiolaria, Sponge 
spicules, Lituolidae, Diatoms. 
(20'00 %), m. di. 0'30' mm., 
angular ; quartz, plagioclase, 
hornblende, augite, magne- 
tite, mica, garnet, tourmaline, 
glauconite, fragments of 
granitic and amphibolic rocks. 
(65 '16 %), amorphous matter, 
minute mineral particles, 
fragments of Radiolaria and 
Diatoms. 
The dredge came up without showing any signs of having 
been at the bottom. It had to be hauled in soon, on 
account of a strong wind rising, and the ship being sur- 
rounded by iceberg.s. Some of the fragments of granitic 
and amphibolic rocks attain a diameter of 2 cm. 
i(60'00 %), many Radiolaria, a 
! few Lituolidae, chiefly Dia- 
i toms. 
(lO'OO %), m. di. 0'20 mm., 
angular and rounded ; quartz, 
orthoclase, rarely plagioclase, 
hornblende, mica, magnetite, 
a, few small glassy volcanic 
fragments. 
(27 '92 %), essentially composed 
of Diatom fragments, with a 
little amorphous matter and 
a few minute mineral par- 
ticles. 
The trawl brought up a number of animals, rocks, and 
pebbles. The rocks and pebbles include granite, con- 
taining orthoclase, plagioclase, quartz, hornblende, and 
mica ; gneiss composed of quartz, black and white 
mica, and garnet ; chloritic quartzite ; fine-grained mica- 
ceous sandstone ; slate formed of sericite with micro- 
liths of rutile ; trachytic pumice with sanidine and 
augite ; limburgite partially transformed into pala- 
gonite ; and some other ancient and recent volcanic 
rocks all very much altered. 
(50 00%), many Radmlaria, some 
Sponge spicules, Astrorhizidae, 
Lituolidae, principally Dia- 
toms. 
(3 '00 %), m. di. 0'07 mm., 
angular ; quartz, felspar, 
hornblende, a few magnetic 
particles, small fragments of 
palagonite, pumice, much 
altered volcanic rock with 
ophitic structure. 
(27 '71 %), composed es.sentially 
of fragments of Diatoms, a 
small quantity of amorphous 
matter and minute mineral 
particles. 
Only a small quantity of the deposit came up in the 
sounding tube. In the trawl there were several pebbles 
and one large piece of rock along with many animals. 
One fragment of grey gneiss weighed 20 kilogrammes, 
and some similar fragments had glacial markings there 
was a basaltic fragment 6 cpi. in diameter, and thirty 
pieces of pumice from 1 to 3 cm. in diameter. 
(10 ’00 %), Radiolaria, Astror- 
hizidae, Lituolidae, chiefly 
Diatoms. 
(I'OO %), m. di. 0'07 mm., 
angular ; quartz, felspar, 
pumice, glassy volcanic 
particles. 
(3 '69 %), a little amorphous 
matter, with minute mineral 
particles and fragments of 
siliceous organisms. 
The trawl brought up pumice stones, pebbles, and many 
animals. There were fifteen fragments of pumice, 
generally all rounded, and varying in diameter from 2 to 
5 cm., and also one flattened angular fragment of pala- 
gonite, 3 or 4 cm. in width, and 1 cm. in thickness. 
Some of the quartz grains are covered with limonite. 
(2 '00 %), Radiolaria, Sponge 
spicules, Lituolidae, Diatoms. 
(1'00%), m. di. 0'07 mm., 
angular ; felspar, hornblende, 
magnetite, pumice, red glassy 
volcanic fragments, manganese 
grains, quartz grains (rare). 
(9 '10 %), amorphous matter, 
fine mineral particles, and 
fragments of siliceous organ- 
isms. 
The trawl was put over, but came up without any of the 
deposit or any bottom-living animals to show that it 
had ever touched the bottom. The presence of Coccoliths 
and Rhabdoliths in this deposit is worthy of notice, as 
they have been absent in those to the south of lat. 55°. 
The greater abundance of Orbulinas and Pulvinulinas 
in the last two stations should also be remarked.
