Depth, 2450 fathoms ; deposit, Globigerina Ooze, containing 66*27 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 6. 1 5 a.m. stopped to sound, and sounded in 2450 fathoms. At 9 a.m. obtained serial 
tcnij'< ratures down to 1500 fathoms. Obtained samples of water from various depths 
f< . 1 analy sis. The carbonic acid was determined in water from 300 fathoms, and amounted 
to 53*6 milligrammes per litre. At 11.30 a.m. completed temperatures, and at
