NARRATIVE OF THE CRUISE. 
903 
The surface currents, as ascertained by the difference between the position of the ship 
deduced from astronomical observations and the ship’s reckoning, were N. 79° E. (true) 
8 miles per day. 
The following anemometer observations were taken when the ship was sounding or 
trawling : —

The deposit in 1035 fathoms in this section was a sandy gravel. The trawl line carried 
away and the trawl was lost, but the tow-net attached to the line at the weights con- 
tained some of the gravel. The larger particles were from 1 to 2 cm. in diameter, brown 
coloured, flattened, ellipsoidal, derived from ancient continental formations, such as 
schist, gneiss, arkose, and sandstone, together with milky and hyaline quartz, felspar, 
augite, magnetite, microclin, hornblende, and glauconite. The glauconite was globular, 
ovoid, elongated, or vaguely triangular, with rounded angles ; many of the particles were 
not so homogeneous as true glauconite, and appeared as aggregates of minerals cemented 
by a green matter. Sometimes they showed a schistoid structure, and often it was difficult 
to say whether the fragments were glauconite or pieces of rocks strongly impregnated with 
a chloritic substance. Mixed up with the above mentioned sandy particles were cal- 
careous Foraminifera, fragments of Molluscs, Brachiopods, Echinoderms, and Polyzoans. 
In 2040 fathoms the deposit was a blue mud containing 33 per cent, of carbonate of 
lime. The trawl was put over at this Station, and although it was over for seven hours, 
it never seemed to have touched the bottom. Two tow-nets were attached to the beam 
of the trawl, and one at the weights in front of the trawl, and it seems almost impossible 
that the trawl could have touched on the mud without these fine nets bringing up some 
traces of it. The trawl, however, contained a specimen of a new genus of Salmonid 
Fish ( Bathylagus atlanticus, Grinth.), several large Medusae ( Atolla wyvillei, Haeckel), 
and several bright scarlet Shrimps. In the tow-nets attached to the weights and trawl 
there were also eighteen species of Phaeodaria, identical with those obtained in the 
deep water of the Pacific, several bright red Copepods, and red Sagittce over 2 inches 
in length. It is impossible to say how near the trawl may have been to the bottom, 
but Mr. Murray considers it quite certain that most, if not all, of the animals above
