small fishes and fish eggs. Bunches of white egg-capsules taken on dead Velellse at the Station 253. 
previous Station developed in a globe into small shells, similar to those found on the 
surface — probably larval Heteropods. Many small pieces of pumice, some covered with 
mould, or Algse, were again taken in the tow-net, and others formed the nuclei around 
which the Lepas was attached. Very little phosphorescence was noticed on the surface 
during the past two weeks, and Pyrocystis had not lately been noticed in the surface 
gatherings.

Clay, containing 
no carbonate of lime, and 
relatively much fewer Eadiolaria than in the deposits further west (see Murray 
and Eenard, Deep-Sea Deposits Chalk Exp.). 
At 4.30 A.M. stopped and put trawl over. At 6 a.m. sounded in 3025 fathoms. 
Obtained serial temperatures down to 1500 fathoms. The carbonic acid was determined 
in water from 400 fathoms and from the bottom, and amounted respectively to 287 and
