Depth, 1990 fathoms; deposit, Globigerina Ooze, containing 92'54 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Cball. Exp.). 
At 9 A.M. shortened and furled sails, and proceeded under steam to sound and 
dredge. At 9.40 a.m. sounded in 1990 fathoms. At 11 a.m. put dredge over and 
veered 2600 fathoms. Took serial temperatures down to 1500 fathoms. The carbonic 
acid was determined in water from 50, 100, and 200 fathoms, and amounted respectively 
to 37 ‘3, 36'8, and 43*1 milligrammes per litre. At 4 p.m. commenced heaving in dredge, 
which came up at 7 p.m. filled with deposit. Made sail. 
Distance at noon from Ascension, 798 miles. Made good 123 miles. Amount of

from this Station (see also i\Iurray and Renard, Deep-Sea Deposits Chalk Exp.) : — 
h'oRA.MiNiFKRA (Brady, Zool. pt. 22). — The pelagic species, which make up about 86 per 
cent, of the carbonate of lime present in the deposit, are marked thus x .
