He states (Konig Akad. der Wissen: Berlin, Feb. 1845)
that it is composed of infusoria, including fourteen
polygastrica, and four phytolitharia. He says that they are
all inhabitants of fresh-water; this is a beautiful example
of the results obtainable through Professor Ehrenberg's
microscopic researches; for Jemmy Button told me that it is
always collected at the bottoms of mountain-brooks. It is,
moreover, a striking fact that in the geographical distribution
of the infusoria, which are well known to have very wide
ranges, that all the species in this substance, although
brought from the extreme southern point of Tierra del Fuego,
are old, known forms.
[2] One day, off the East coast of Tierra del Fuego, we saw
a grand sight in several spermaceti whales jumping upright
quite out of the water, with the exception of their tail-fins.
As they fell down sideways, they splashed the water high up,
and the sound reverberated like a distant broadside.
[3] Captain Sulivan, who, since his voyage in the Beagle, has
been employed on the survey of the Falkland Islands, heard
from a sealer in (1842?), that when in the western part of
the Strait of Magellan, he was astonished by a native woman
coming on board, who could talk some English. Without doubt
this was Fuega Basket. She lived (I fear the term probably
bears a double interpretation) some days on board.
