bottom, 1 "02602. 
Depth, 2275 fathoms; deposit, Globigerina Ooze, containing 72 - 93 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 6.45 a.m. shortened and furled sails, and got up steam to sound. At 8 a.m. 
sounded in 2275 fathoms. Obtained serial temperatures down to 1500 fathoms. At
