Depth, 1985 fathoms; deposit, Globigerina Ooze, containing 65'81 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 4 A.M. shortened and furled sails, and proceeded under steam. At 6 a.m. sounded 
in 1985 fathoms. Put over trawl and veered 2500 fathoms. Obtained serial temperatures 
down to 1500 fathoms. The carbonic acid was determined in water from 200, 800, and 
1975 fathoms, and amounted respectively to 35 "8, 46 ‘2, and 51 ’2 milligrammes per litre. 
At 1 p.M. commenced heaving in trawl, but at 2.30 p.m. the trawl-rope carried away, and 
the trawl with its content.s, apparently heavy, and 2000 fathoms of line, were lost. 
Matle all plain sail and proceeded. One or two large albatrosses {Diomedea exulans) 
were seen. 
Valparaiso distant at noon, 3608 miles ; Bass Islands about 120 miles. Made good 
87 mifes. Amount of current 13 miles, direction N. 
rR/>M F0RA.MIXIFERA (Brady, Zool. pt. 22). — The following species of Foraminifera were 
iHi I)Ern«rr. observed during the examination of the deposit from this Station ; the pelagic species, 
which make up about 76 per cent, of the carbonate of lime present in the deposit, are 
marked thus x : —
