The wind now gradually freshened, and for the
next three day^s we went on onr course witli a line
breeze, force from 4 to 7, fi‘om the sontliAvard,
sounding daiiy at a depth of about 2,700 fathoms,
with a bottom of reddisli-grey ooze. On Tuesday the
2 tth the trawl was put OA'er in 2,175 fathoms, Lat.
38° 3' N., Long. 39° 19' W., ahont 500 miles from the
cores. As in most of the deep trawls on grey mud,
a number of the zooecia of delicate branching polyzoa
were entangled in the net. One of these on this
occasion was very remarkahle from the extreme
length (4 to 5 mm.) of the pedicels on which its
avicularia were placed. Another very elegant species

cells, reminding one of those of some of the more
ornamented Lepralue.
On Wednesday the 25th a serial sounding (Lig. 4)
shoAved th a t the layer of Avarni Avater AAdiicli envelops
Permudas Avas gradually thinning out and disappearing,
and a sounding on the 27tli (Lig. 5) brought out
the same result even more clearly, the isotherm of

On Monday the 30th of Ju n e we sounded in 1,000
