At last, on the 24th of July, we came to the end of the Channel, and
attained the open sea; the wind was tolerably favourable, and on the
2nd of August we were off Gibraltar, where we were becalmed for
twenty-four hours. The captain threw several pieces of white
crockeryware, as well as a number of large bones overboard, to show
how beautifully green such objects appeared as they slowly sank down
beneath the sea; of course this can only be seen in a perfect calm.

In the evening we were greatly delighted by numbers of moluscae
shining through the water; they looked exactly like so many floating
stars, about the size of a man's hand; even by day we could perceive
them beneath the waves. They are of a brownish red, and in form
resemble a toadstool; many had a thick pedicle, somewhat fimbriated
on the under part; others, instead of the pedicle, had a number of
threads hanging down from them.

4th August. This was the first day that it was announced by the
heat that we were in a southern latitude; but, as was also the case
the following day, the clear dark blue sky that generally overarches
the Mediterranean in such exceeding loveliness, was still wanting.
We found, however, some slight compensation for this in the rising
and setting of the sun, as these were often accompanied by unusual
forms and colours of the clouds.

We were now off Morocco, and were fortunate enough today to perceive
a great number of bonitos. Every one on board bestirred himself,
and on every side fish hooks were cast overboard; unluckily only one
bonito allowed himself to be entrapped by our friendly invitations;
he made a dart at the bait, and his good-natured confidence procured
us a fresh meal, of which we had long been deprived.
