The sounding tube brought up about half a litre of the 
deposit. The trawl came up with the netting much 
torn, but in the bag there were a large quantity of red 
or chocolate clay, many manganese nodules and animals. 
The nuclei of the nodules are in some cases fragments 
of felspathic basalt, black and opaque; in others they 
arepiecesof basalt-glass coated with a pal agonitic reddish 
or yellowish zone of decomposition. The upper layers 
of the deposit from the sounding tube contained appa- 
rently many more Foraminifera than the lower. The 
clay mixed up with the nodules, most probably came 
from the surface layers on account of the large quantity 
of carbonate of lime as found by the analysis of a sample 
taken from the trawl. 
The major part of these deposits is made up of fragments 
of Polyzoa with fewer of the other organisms mentioned, 
the majority of the fragments being a little more than 
5 mm. in diameter. There were a few greenish casts 
of the carbonate of lime shells. 
Only a small quantity of the deposit came up in the 
sounding tube. 
(6 '64 %), a small quantity of 
amorphous matter, minute 
mineral fragments and coal 
dust, some flocculent organic 
matter. 
The carbonate of lime in these deposits is chiefly com- 
posed of the fragments of Molluscan shells. The mineral 
particles consist chiefly of rounded fragments of quartz 
and particles of felspar.

A small piece of shell was all that came up in the 
sounding tube. 
A small quantity of mud came up on the grease of the 
sounding tube, and gave the organisms mentioned, 
but there was insufficient for analysis. ( 
A small quantity came up attached to the grease of the 
sounding tube, much the same as-that obtained at the 
last station, but it eontained more Foraminifera and 
many more glauconitic casts and glauconite particles 
of a dark green colour. There was insufficient for 
analysis.

The pelagic Foraminifera are very abundant in this 
deposit, a great many of them being filled with pale 
yellow aud green glauconite. Some of the Foraminifera 
are macroscopic.
