condition, and very frequently with Diatoms and other minute organisms in the Ho.vo Kosa 
interior. Not more than one or two specimens of Pyrocystis were observed in the 
tow-nets during this time. Ceratium {Peridinium) tripos was also abundant, but never- 
observed in catena. Spherical jelly-masses, in which were minute Diatoms {CoscinodAscus 
and Navicida), were very abundant, as well as Oscillatoriaceee, Medusae, Diphyes, 
Sagitta, Aphroditacean larvae, Evadne, numerous Copepods, Cirriped larvae, and 
Appendicularia. 
Shortly after leaving Hong Kong the screw was taken up, and was found to be covered 
with Tuhularia, Caprella, small Copepods, and Balanus, very much like what was 
observed after leaving the Cape (December 20, 1873).

Density at 60° F. at surface, 1 ‘02538 ; bottom, 1 ‘02568. 
Depth, 2100 fathoms ; deposit. Blue Mud, containing only a trace of carbonate of 
lime (see Murray and Kenard, Deep-Sea Deposits Chalk Exp.). 
At 6 A.M. got up steam. At 9.15 a.m. shortened and furled sads. At 9.30 a.m. 
proceeded under steam and sounded in 2100 fathoms about half-way between Cajic 
Bojeador, N.W. extremity of Luzon Island, and Macclesfield Bank, and about the middle 
of the China Sea. At 11 a.m. put trawl over. At 1 p.m. obtained serial temperature> 
down to 1000 fathoms. At 3.15 p.m. commenced heaviug in trawl, which came up at 
5 P.M. with only one Caridid shrimp and a small fish. It is probable that the trawl 
never reached the bottom. Made sail.
