At 11.15 A. M. shortened and furled sails, and proceeded under steam to sound and 
trawl. At 12.30 p.m. sounded in 1715 fathoms. The sounding-tube had sunk a foot 
into the liottom, and brought up over a litre of the ooze ; the lower layers were more 
comjiact than the upper. Put trawl over and veered 2200 fathoms. Obtained serial 
temiienitures. The carbonic acid was determined in water from 400 fathoms, and 
amounted to 43*G milligrammes per litre. At 4.15 p.m. commenced heaving in trawl, 
wliich came up at 5.45 p.m. bottom up, but with a shrimp entangled in the meshes of 
the net. It appears that the small lead at the end of the trawl had become hitched 
round the beam, the net being thus doubled up, and the shrimp was found in the fold thus 
formed. In one of the tow-nets at the trawl were a great many dead empty shells of 
Foraminifera which evidently came from the bottom. Made sail. Birds as noted at 
Station 229 were seen. 
Tristan da Cunha distant at noon, 865 miles. Made good 135 miles. Amount of 
current 27 miles, direction S. 52° W.
