Depth, 2425 fathoms ; deposit, Red Clay, containing no carbonate of lime (see 
Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 3.15 A.M. shortened and furled sails, and got up steam. At 5.15 a.m. stopped, 
and at 6 a.m. sounded in 2425 fathoms ; the tube brought up a considerable quantity 
of Red Clay. At 8 a.m. put over trawl. At 10 a.m. obtained serial temperatures 
down to 1500 fathoms. In the forenoon sent whaler away to collect surface animals. 
Sent down two pressure gauges, water-bottle, and a series of small wooden blocks 
of different kinds of wood to test the effect of pressure at great depths. The carbonic 
acid was determined in water from 50 fathoms, and amounted to 3 2 ‘8 milligrammes 
per litre. At 4.45 p.m. hove up trawl with only a few pumice-stones, some shrimps, 
two fishes, and a Brachiopod on one of the pumice-stones. Made sail. Several 
sooty albatrosses were seen, and one was taken with hook and line, also a few white 
albatrosses, black prions, light- coloured prions, black and white petrels. A booby [Sula 
fusca) alighted on one of the quarter boats and was caught. On the 7th a flock of swallows 
[Hirundo gutturalis) alighted on the ropes and ports of the ship in an exhausted condition, 
and four or five were caught by the hand ; their stomachs were well filled with insect 
remains. A thrush-like bird and several finches were also seen. 
Distance at noon from No Sima lighthouse, 514 miles ; from Redfield Rocks, 
448 miles. Made good 56 miles. Amount of current 4 miles, direction W. 
The following species are recorded in the Zoological Reports from the trawl at this 
Station ; —

was taken at Station 184. 
Fishes (Gunther, Zool. pt. 57). 
Gonostoma gracile, n.sp. One specimen ; obtained also at Station 232, 345 fathoms. 
In addition to the foregoing, the Station-book records a Brachiopod on pumice-stone, 
and another Sternoptychid fish, 2 ^ inches in length.
