Only a small quantity of ooze came up in the sounding 
tube and proved to be in all respects the same as that 
at Station 89. 
I'OO %), a few Radiolaria and 
Sponge spicules, Haplophrag- 
mium. 
(I'OO %), m. di. 0'08 mm., 
rounded and angular ; quartz 
grains covered with Umonite, 
monoclinic and triclinic 
felspars, augite, hornblende, 
mica, magnetite, pumice, vol- 
canic glass. 
(37'05 %), amorphous matter, 
with minute fragments of 
minerals and siliceous organ- 
isms. 
All the pelagic Foraminifera found in this deposit are 
large and well developed, especially Pulvinulina 
menardii. 
I'OO %), a few Radiolaria and 
Sponge spicules, Astrorhizidse, 
Lituolidae. 
(5 '00 %), m. di. O'lO mm., 
angular ; fragments of vol- 
canic rocks, monoclinic and 
triclinie felspars, volcanic 
glass altered to palagonite, 
magnetite, augite, hornblende, 
olivine. 
(36'85 %), amorphous matter, 
with fragments of minerals 
and siliceous organisms. 
Some of the shells are macroscopic. The dredge did 
not bring up any of the deposit. The increase in the 
minerals point to the approach to the island of St. 
Vincent. 
.'00 %), a few Radiolaria and 
Sponge spicules. 
(70 '00 %), m. di. O'lO mm., 
angular ; fragments of vol- 
canic rocks and volcanic glass, 
olivine, augite, hornblende, 
magnetite, felspar, black mica, 
quartz. 
(20 '71 %), amorphous matter, 
with minute fragments of 
minerals and siliceous organ- 
isms. 
A very great many particles of volcanic sand of a red, 
black, and yellow colour are present, derived from the 
disintegration of the rocks of the islands. 
■00 %), a few Sponge spicules. 
Diatoms. 
(65'00 %), m. di. O'lO mm., 
angular ; fragments of vol- 
canic rocks, some of them 
glassy, augite, magnetite, 
small crystals of olivine, horn- 
blende, black mica, palagonite. 
(20 '35 %), amorphous matter, 
with minute fragments of 
minerals and siliceous organ- 
isms. 
A few of the organisms are macroscopic. With the 
exception of the Foraminifera all the organisms are, 
more or less, in a fragmentary condition. 
•00 %), a few Sponge spicules. 
(70'00 %), m. di. 0'15 mm., 
angular ; fragments of vol- 
canic rocks, volcanic glass, 
lapilli, felspar, augite, mag- 
netite, olivine, black mica. 
(15 '37 %), amorphous matter, 
with many minute fragments 
of minerals. 
Some of the organisms are macroscopic, though chiefly 
fragmentary. Many of the lapilli are highly altered. 
(3 '00 %), m. di. 0'20 mm., 
angular; fragments of volcanic 
rocks, glassy particles, felspar, 
augite. 
(2'80 %), flocculent organic 
matter, with amorphous 
matter. 
This deposit is chiefly composed of calcareous Algae of a 
white and pink colour, which make up fully 40 per 
cent, of the carbonate of calcium. These white and 
pink particles measure from 1 to 7 mm. in diameter. 
(I'OO %), m. di. O'lO mm., 
angular; fragments of volcanic 
rocks, felspar, augite, volcanic 
glass, magnetite. 
(9 '53 %), organic matter, am- 
orphous matter, and minute 
fragments of minerals. 
The mean diameter of the particles making up this 
sand is 2 mm. Nearly two-thirds of these particles 
are made up solely of Arnphistcgina lessonii, the re- 
mainder of a few OrhitoliUs and other Foraminifera, 
fragments of Polyzoa, Echinoderms, and calcareous 
Algae. 
( 00 %), Sponge spicules, 
Radiolaria, Lituolidse. 
(25 '00 %), m. di. 0'15 mm., 
angular and rounded ; frag- 
ments of volcanic rocks and 
volcanic glass, felspar, olivine, 
magnetite, augite. 
(15'41 %), amorphous matter, 
green flocculent organic mat- 
ter, minute fragments of mine- 
rals and siliceous organisms. 
With the exception of the Foraminifera, the majority of 
the organisms are in a fragmentary condition ; some 
are macroscopic. The Gasteropods and Lamellibranchs 
appear to be chiefly larval forms.
