Ih'jith, 1450 tat horns ; deposit, Globigerina Ooze, containing 82*31 per cent, of 
carbonate of lime (see i\Iurray and Renard, Deep-Sea Deposits Chall. Exp.). 
-\t 4 .\..M. sliortened and furled sails, and proceeded under steam. At 6 a.m. sounded in 
1450 fathoms. At 7 a.m. put trawl over and veered 2000 fathoms. Obtained serial 
tcm|K'ratures down to bottom. The carbonic acid was determined in water from 
200, 400, and 800 fathoms, and bottom, and amounted respectively to 47*3, 48*8, 53*2, 
and 55*6 milligrammes per litre. At 1 p.m. commenced heaving in trawl, which came 
up at 4.15 P.M. with numerous specimens, about a peck of the ooze, in which were 
numerous manganese nodules, some volcanic pebbles, and pieces of rock. At 4.30 p.m. 
made all plain sail. Molly mauks, stinkers {Procellaria maxima), mutton birds, and 
C’apt' pigeons were seen, and a molly mauk was shot, but a boat could not be lowered to 
pick it up.

current 10 miles, direction W.
