Diatoms. Oscillatoriacese ( Trichodesmium ?) were present in considerable quantities 
in the tow-net, but in isolated small bundles, not in masses as they are said to occur 
frequently.”

Depth, 1900 fathoms; deposit, Globigerina Ooze, containing 74'50 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 6 a.m. sounded in 1900 fathoms, and at 7.30 a.m. put over dredge with cwt. 
attached at 500 fathoms from it, with 2600 fathoms of rope. The tow-net had been out 
all Dight, and in the morning was found to contain some interesting specimens. At 
10 a.m. sent down a stop-cock water-bottle to 300 fathoms, and slip water-bottle to 
the bottom, and obtained serial temperatures. At 1.30 p.m. commenced heaving in 
dredge, which came up about 4 p.m. with several specimens. 
Sombrero Island distant at noon, 1074 miles. Made good 68 miles. Amount of 
current 16 miles, direction S. 73° W. 
The following species are recorded in the Zoological Reports from the dredge at this 
Station : —
