of the western flank of the great central elevation of
the Atlantic. The temperature-determinations had
throughout the Avhole of this section been of the
greatest interest ; the lov'est temperatures which we
had met with previously had been in the neighbourhood
of Eernando Noronha, nearly under the
equator ( -f 0°-2 C.) ; we were morally certain th a t
this cold water Avelled up from the Antarctic Sea in
the western trough of the Atlantic, and we fully
expected to intersect the line of the supply. In this
however we were disappointed ; we met Avith no temperature
so loAA' as the loAA'est temperature under the
equator {+ 0°*2 C.), and it was only three years
afterwards on our nortliAvard voyage th a t Ave struck
the main hody of the cold indraught.
On the 11th we sounded in 1,900 fathoms with a
bottom of glohigei’ina-ooze and a bottom temperature
of 1°‘3 C., and put over the trawl, and during its
absence took a series of shallow temperature soundings
at intervals of 25 fathoms down to 100. The

in shallow Avater on coral reefs, and in miscellaneous
natural history collections. Fungia symmetricawAS first
described by Count Pourtales from deep water 350 to
450 fathoms in the Strait of Elorida. The corallum
is circular, plano-convex ; the Avall is perfectly plane
and very little perforated, Avith a small convex umbilicus
in the centre. The costse, Avhich correspond
