(5 '66 %), amorphous matter, 
fine mineral particles, floccu- 
lent matter, and fragments of 
siliceous organisms. 
This deposit contains hut little fine calcareous of clayey 
matter and is almost entirely composed of i.solated 
white Foraminifera shells. There were in the dredge 
many small, irregular, phosphatic concretions, 1 to 
4 centimetres in diameter, coated with manganese, and 
containing glauconite and Foraminifera.

(I'OO %), m. di. 0'12 mm.,

clinic and triclinic felspars, 
augite, hornblende, magnetite, 
olivine transformed into ser- 
pentine, bronzite, fragments 
of volcanic glass and allied 
rocks, manganese grains, 
quartz. 
(5 ‘66 %), amorphous matter, 
with minute mineral particles 
and fragments of Diatoms. 
This deposit, like that obtained at Station 143, is remark- 
able for the small quantity of minute and amorphous 
particles. Some rolled fragments of quartz attain a 
diameter of about 1 mm. The pelagic Foraminifera 
are of the small and thick-shelled varieties peculiar 
to the colder waters of the ocean, although they 
are not of the typical Arctic and Antarctic varieties, 
Globigerina iulloides predominating.

(65’00 %), m. di. 0'15 mm., 
angular and rounded; plagio- 
clase, felspar, augite, olivine, 
magnetite, small lapUli of 
vitreous basaltic rocks. 
(7 ’87 %), minute fragments of 
minerals and Diatoms, amor- 
phous matter, vegetable mat-

Four hauls were taken with the dredge, two at 50, one 
at 75, and one at 100 fathoms. The bottom was 
covered with Polyzoa of several species, the swabs and 
dredge being filled with them, together with the 
remains of a great many other animals.

Two hauls of the dredge were taken, one in 85 and the 
other in 140 fathoms when a small quantity of deposit, 
similar to that described at Station 144 a, came up. 
The animals were similar to those obtained on the 
previous day when dredging nearer to Marion Island. 
A little mud in the dredge indicated the same kind of 
deposit as in the shallower depths on the same day. 
One of the most successful hauls of the cruise was made 
with the dredge, it being filled with animals.

lizidae, Lituolidae, many 
jtiatoms. 
(I'OO %), m. di. O'lO mm., 
angular ; felspar, plagioclase, 
microcline, hornblende, mag- 
netite, garnet, tourmaline, 
pumice. 
(9'64 %), fragments of Diatoms, 
a little amorphous matter 
and a few mineral particles. 
No Rhabdoliths or Orbulinas were observed in this 
deposit ; their southern limit seems to have been passed 
at this point. There was a fragment about 1 cm. in 
diameter chiefly formed of a lamellar mineral, probably 
bronzite, with metalloid lusti’e, extinction parallel to 
the direction of the cleavage, hardly fusible. It was 
attached to some pale green serpentinous matter. The 
trawl was used and one of the best hauls during the 
cruise was obtained, the bag being filled with animals. 
In the trawl were five irregular scoriaceous lapUli, 
from 1 to 5 centimetres in diameter ; they are more or 
less porous, like pumice, but the viti-eous substance is 
deep brown.
