Depth, 2040 fathoms; deposit, Globigerina Ooze, containing 32'69 per cent, of 
carbonate of lime (see Murray and Eenard, Deep-Sea Deposits Chall. Exp.). 
At 4.45 A.M. got up steam. At 9 a.m. shortened and furled sails, and proceeded 
under steam to sound and trawl. At 10 a.m. sounded in 2040 fathoms. Put trawl over. 
Obtained serial temperatures down to 1500 fathoms. The carbonic acid was determined 
in surface water, and amounted to 38*5 milligrammes per litre. At 4 p.m. commenced 
heaving in trawl, which came up at 6 p.m., containing a few Crustaceans, &c., but, 
although the trawl must have been near, it showed no signs of having touched the 
bottom. At 7.10 p.m. made sail. Albatrosses, mutton birds, black night hawks, prions, 
and Thalassidromas were seen. 
Lobos Island distant at noon, 456 miles; Valdes Peninsula, east coast of South 
America, distant about 300 miles. Made good 176 miles. Amount of current 13 miles, 
direction N. 33° E. 
The following species are recorded in the Zoological Reports from the trawl at this
