Depth, 1600 fathoms; deposit, Diatom Ooze, containing 34'63 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 8 a.m. got up steam. At 9.20 a.m. shortened and furled sails, and proceeded 
uml r -t am to -ound and trawl. At 10 a.m. put trawl over, veering 2000 fathoms. At 
II a.m. sounded in 1600 fathoms. At 1.20 r.M. obtained serial temperatures. The 
■aioniia acid w;is determined in water from the surface and 100 fathoms, and 
no rit 1 n -pcctively to 54*2 and 56'9 milligrammes per litre. At 4.45 p.m. the trawl 
« arm up witii numerous specimens, — even a more remarkable haul than yesterday’s. A 
t in • was -nt down on the trawl line, but did not work successfully. At 4.50 p.m. 
all plain sail. At 10.15 p.m. observed Hog Island on port bow. In the course of
