Depth, 2900 fathoms ; deposit, Kadiolarian Ooze, containing only a trace of 
carbonate of lime (see Murray and Eenard, Deep-Sea Deposits Chall. Exp.). 
At 4.15 A.M. shortened and furled sails and got up steam. At 6.45 a.m. sounded in 
2900 fathoms. This deposit presented a great similarity in physical as well as micro- 
scopical properties to the deepest sounding (Station 225). Obtained serial temperatures 
down to 1500 fathoms. The carbonic acid was determined in bottom (?) water, and 
amounted to 34'3 milligrammes per litre. At 1.30 p.m. completed temperatures and made 
all plain sail. Gannets, boatswain birds, fulmars, and land-birds like snipe were seen. 
Venus Point, Tahiti, distant at noon, 1505 miles. Made good 44 miles. Amount of 
current for the last two days 34 miles, direction E.
