At 9.30 a.m. got up steam. At 11 a.m. shortened and furled sails. At 11.30 a.m. 
proceeded under steam to sound. At 1 p.m. sounded in 2550 fathoms, but the line 
carried away. At 2 p.m. obtained serial temperatures down to 1500 fathoms. At 
4.30 p.m. made all plain sail. At 7.30 p.m. got up steam, and at 8 p.m. shortened 
and furled sails, and proceeded under steam. The following birds were observed about 
the ship : — Diomedea exulans, Diomedea melanophrys, another albatross very like the 
last but with a darker bill, Cape pigeons, a few prions, and a black bird resembling 
Pi'oeeUaria seqvinoctialis observed in the south. 
Distance at noon from Cape Farewell, 936 miles. Made good 43 miles. Amount of 
current 27 miles, direction S. 20° E. 
Surface Org anisms . — The following species is recorded from the surface at this 
Station : — 
Cephalopoda (Hoyle, Zool. pt. 44). 
Taonius suhmi (Lankester), n.sp. 
In addition, the following are recorded in the note-books : — Many Foraminifera 
( Globigerina and Pulvinulina, Pulvinulina micheliniana especially abundant, along 
with Globigerina bull&ides, var. triloba ; the sarcode of Pulvinulina, after dissolving 
away the shell, showed no traces of symbiotic Algae, but contained many oil-globules) ; 
Acanthometrae and other Radiolarians ; Diphyes, Abyla, and other Siphonophorae

D«pth, 2G00 fathoms; deposit, Red Clay, containing 6*54 per cent, of carbonate

Under steam all night. At 7.55 a.m. stopped and put dredge over, and veered 
:!500 fathoms. At 11 a.m. sounded in 2600 fathoms. At 2 p.m. commenced heaving 
in dredge, which came up at 4.30 p.m. nearly empty. It had been to the bottom, but 
the fine ooze was completely sifted out; a few' specimens were found adhering to the 
net. The carbonic acid was determined in water from 50 fathoms, and amounted to
