by an English botanist as a very rare British species, occurred on the
dripping rocks by the roadside, and many wild plants were in flower on
the lower grounds. Even butterflies of three kinds, two of which (Colias
edusa and Cynthia cardui) are also found in Britain, occurred, although
in small numbers, and at the Pass of the Curral coleoptera of the genera
Pimelea and Scarites, were met with under stones along with minute
landshells, Bulimus lubricus, Clausilia deltostoma, and a Pupa.
LEAVE MADEIRA.
After a stay of eight days, we left Madeira for Rio de Janeiro, and on
January 2nd picked up the south-east trade wind, and passed through the
Cape de Verde Islands to the southward between Mayo and St. Jago. Two
days afterwards, in latitude 9 degrees 30 minutes North, and longitude 22
degrees 40 minutes West, a slight momentary shock, supposed to be the
effect of an earthquake, was felt throughout the ship.
TRY FOR DEEP-SEA SOUNDINGS.
On the 11th an attempt was made to strike deep-sea soundings, but failed
from the drawing of a splice used to connect two portions of the
spun-yarn employed. On the following day the attempt was repeated by
Captain Stanley, unsuccessfully, however, no bottom having been obtained
at a depth of 2400 fathoms. Still a record of the experiment may be
considered interesting. At three P.M., when nearly becalmed in latitude 1
degree North, and longitude 22 degrees 30 minutes West (a few hours
previous to meeting the south-east trade) the second cutter was lowered
with 2600 fathoms of line (six yarn spun-yarn) in her, coiled in casks,
and a weight consisting of twelve 32 pounds shot--in all, 384 pounds,
secured in a net bag of spun yarn. The jolly-boat was in attendance to
tow the cutter as fast to whirlwind as she drifted, so as to keep the
line during the time it was running out as nearly up and down as
possible. The following table shows when each 100 fathoms passed over the
stern, the whole 2400 fathoms of line having taken 38 minutes and 40
seconds to run out:
