At 8 a.m. passed small quantity of gulf- weed. At 11.30 a.m. shortened and furled 
sails and got up steam to sound. At 1 p.m. sounded in 2325 fathoms, and sent down 
thermometer and slip water-bottle. At 2 p.m. life-boat was lowered, and naturalists went 
away to collect gulf- weed and surface animals; returned at 4.45 p.m. Took serial 
temperatures at intervals of 100 fathoms down to 1500 fathoms, and proceeded 
under all plain sail. 
Sombrero Island distant at noon, 844 miles. Made good 126 miles. Amount of 
current 11 miles, direction N. 69° W. 
Surface Organisms. — The following are recorded in the note-books as having 
been procured among the gulf -weed : — Campanularia ; Dendroeoelous Planarians, 
Spirorbis ; Lepas, B alanus, My sis, Paliernon (?), Nautilograpsus, larger Brachyuran ; 
Scyllsea pelagica; Flustra; Aniennarius. A grampus and many flying-fish were seen 
this morning. 
Moseley writes : “We now began to see plenty of patches of gulf- weed (Sar- 
gassum bacciferum). I was astonished at its light yellow colour, as I had only seen 
dark dried specimens. Amongst the weed procured with a boat were the nests of the 
well-known little fish Antennarius. The nests consist of irregularly spherical masses of 
the weed, fastened together by means of highly elastic threads, which look like wetted 
cotton, indeed I took it for such at first sight ; in the centre of the masses are the 
eggs. A fish was caught and was observed to use his pectoral fin as a regular 
prehensile organ to lay hold of the weed with ; the end of the long armed fin looks 
very like the hand of a frog.”
