Additional Observations. 
Siliceous Organisms. 
Minerals. 
Fine Washings. 
(1 ’00 %), fragments of Eadio- 
laria and Sponge spicules, 
Lituolidas. 
(2-00%), m. di. O'lO mm., 
angular ; pumice, felspar, 
magnetite, augite. 
(30 '57 %), amorphous matter, 
with minute fragments of 
minerals and siliceous organ- 
isms. 
The majority of the organisms in this deposit are in a 
fragmentary condition. 
(1 "00 %), one or two Eadiolaria, 
Lituolidse, Diatoms. 
(I'OO %), m. di. 0'07 mm., 
angular ; pumice, augite, 
felspar, magnetite, some small 
rounded grains of quartz 
covered with limonite, mica. 
(35 '62%), amorphous matter, 
with minute fragments of 
minerals, Eadiolaria, and 
Diatoms. 
The deposits at this and the preceding stations are 
remarkable for the relatively small number of perfect 
shells of pelagic Foraminifera ; those present are 
fragmentary. Pulvinulina menardii appears to be 
nearly, if not quite, absent in this part of the Atlantic. 
A quantity of ooze came up in the water-bottle. 
I'OO %), Eadiolaria and Sponge 
spicules, Lituolidae. 
(I'OO %), m. di. 0'06 mm., 
angular ; pumice, lapilli, 
felspar, magnetite, augite, 
olivine. 
(18'21 %), amorphous matter, 
with minute fragments of 
minerals and siliceous organ- 
isms. 
Note in these deposits the complete, or nearly complete, 
absence of the shells of Pteropods and Heteropods in 
the deeper soundings. 
I'OO %), Eadiolaria, Sponge 
spicules, AstrorhizidjE, Lituo- 
lidae, a few Diatoms. 
i 
(2'00 %), m. di. 0'08 mm., 
angular ; pumice, lapilli, 
monoclinic and triclinic fel- 
spars, magnetite, black mica, 
augite, olivine. 
(25 '91 %), amorphous matter, 
with fragments of minerals 
and siliceous organisms. 
The washings of the deposit, on being passed through 
sieves, contained many small round fragments of 
pumice, about 1 cm. in diameter, also a good many 
otoliths of fish and fragments of Pteropods and other 
Molluscan shells. Some of the pumice nodules are 
overgrown by Serpulx. 
I'OO %), Eadiolaria, Astror- 
! liizidae, Lituolidae, a few 
' Diatoms.

f 
(75 '00 %), m. di. O'lO mm., 
angular ; pumice, fragments 
of volcanic rocks, scoriaceous 
lapilli, monoclinic and triclinic 
felspars, magnetite, augite, 
olivine, palagonite, manganese 
grains. 
(17 '46 %), amorphous matter, 
with fragments of minerals 
and siliceous organisms. 
The washings obtained by passing a large quantity of the 
mud through sieves were almost wholly made up of the 
dead shells of Pteropods and Heteropods, with those of 
a few bottom-living Molluscs. There were several large 
fragments of a Gorgonoid Coral coated with manganese. 
All the coral was dead and in the same condition as at 
Station 3. There were in addition some fragments of 
volcanic rocks, about 1 cm. in diameter, also coated 
with manganese. 
I'OO %), a few Eadiolaria, 
j Haplophragmium, imperfect 
brown casts. 
(2 '00 %), m. di. 0'08 mm., 
angular and rounded; small 
rounded grains of quartz, 
felspar, hornblende, mag- 
netite, mica, volcanic glass, 
manganese grains. 
(39 '23 %), amorphous matter, 
with minute fragments of 
minerals and siliceous organ- 
isms. 
Pulvinulina menardii appears in this deposit ; it is 
absent in the soundings to the north of this station. 
' 
A piece of a Gorgonoid Coral covered with manganese 
came up in the sounding tube ; there were also some 
pieces taken in the dredge. There was nothing further 
to indicate the nature of the deposit (see Station 3). 
1 '00 %), one or two Eadiolaria, 
Sponge spicules, Lituolidae.

(I'OO %), m. di. 0'07 mm., 
angular and rounded ; small 
quartz grains covered with 
limonite, felspar, augite, 
hornblende, pumice, mag- 
netite, mica, a few grains of 
manganese. 
(33'62 %), amorphous matter, 
with minute fragments of 
minerals and siliceous organ- 
isms. 
The manganese in the last three soundings shows that it 
must be abundant over a large area. 
'•‘OO %)) Sponge spicules, 
Eadiolaria, a few arenaceous 
1 Foraminifera. 
(I'OO %), m. di. 0'07 mm., 
angular and rounded ; quartz 
grains covered with limonite, 
monoclinic and triclinic 
felspars, magnetite, augite, 
hornblende, volcanic glass. 
(39 '50 %), amorphous matter, 
with minute fragments of 
minerals and siliceous organ- 
isms. 
This deposit contains a considerable quantity of amor- 
phous clayey matter. The specimens of Pulviniduia 
menardii obtained here are very large, some macroscopic.
