Acanthometrse and compound Eadiolaria, Sagitta, Setella and small blue Copepods, 
Amphipods, Sergestes larvae, Atlanta, Pleuropus [ = Cavolinia'] and other Pteropods, and 
small fishes. The tow-net at the weights contained a little deposit, along with many 
Challengeridae and other Eadiolaria, red Cypridinse, and ordinary surface organisms.

Depth, 1425 fathoms; deposit, Pteropod Ooze, containing 93'77 per cent, of 
carbonate of lime (see Murray and Eenard, Deep-Sea Deposits Chall. Exp.). 
At 7.30 A.M. got up steam, and at 8.30 a.m. shortened and furled sails and proceeded 
under steam to sound and dredge. At 9 a.m. sounded in 1425 fathoms. Put large 
dredge over and veered 1900 fathoms. Took serial temperatures. At 2 p.m. commenced 
heaving in dredge, which came up at 3 p.m. with many specimens. The dredge and 
attached tow-nets brought up about ten litres of the ooze and a few pumice-stones. 
Made sail. Sea phosphorescent. No birds were seen from this date till approaching 
Ascension on March 27.
