cylindrical form, and blunt at the end; they put out two little fins with
which they swam.

I was unfortunately too unwell this day to describe all the other
specimens we caught, which were numerous. The sea was full of small
acalepha, and in the midst of a shoal of these a whale was seen.

Birds first re-appeared again. I saw a large flock of two kinds, but was
not near enough to ascertain what they were. I have before noted the fact
that almost at the exact point where the southern birds of the family
