In addition, the following are recorded in the note-books from the tow-nets at the 
surface and down to 50 fathoms ; — Peridinium tri'pos, Glohigerina, Acanthometrse and 
compound Eadiolaria, Carchesium, Medusae, Beroe, Echinoderm larvae, Sagitta, Alciojpa, 
Aphroditacean larvae, Planarians, Cypridina, Hyperids, Zoeae of Decapods, Archizoea, 
Atlanta, Firoloida, Limacina and other Pteropods, Cymbulia larvae, Membranipora 
larvae, Appendicidaria, and many specimens of a stage of 'Doliolum, which gave the 
tow-net a slight reddish appearance. The tow-net sent down to 50 fathoms contained a 
number of Globigerinse, which were not noticed in the surface hauls, and several organisms 
apparently indicating the presence of shore or river water, such as Echinoderm larvae, 
Membranipora larvae, Planarians, Carchesium, and Aphroditacean larvae.

Density at 60° F. at surface, 1 •02633 ; bottom, 1 '02614. 
Depth, 2900 fathoms; deposit, Eed Clay, containing no carbonate of lime (see 
Murray and Eenard, Deep-Sea Deposits Chalk Exp.). 
At 1.30 P.M. shortened and furled sails, and proceeded under steam, and at 2.30 p.m. 
sounded in 2900 fathoms. Over a litre of the deposit was obtained in the sounding-tube, 
the upper layers having a dark slate colour, while the lower layers had a tinge of red and 
w’ere more compact. Obtained serial temperatures. At 5 p.m. completed observations, 
and at 5.20 p.m. made sail. Albatrosses, black petrels, and another petrel were seen. 
Tristan da Cunha distant at noon, 1462 miles. Made good 89 miles. Amount of 
current for the past two days 26 miles, direction S. 70° E.
