[6] The flies which frequently accompany a ship for some days
on its passage from harbour to harbour, wandering from the
vessel, are soon lost, and all disappear.
[7] Mr. Blackwall, in his Researches in Zoology, has many
excellent observations on the habits of spiders.

[9] I found here a species of cactus, described by Professor
Henslow, under the name of Opuntia Darwinii (Magazine of
Zoology and Botany, vol. i. p. 466), which was remarkable
for the irritability of the stamens, when I inserted either a
piece of stick or the end of my finger in the flower. The
segments of the perianth also closed on the pistil, but more
slowly than the stamens. Plants of this family, generally
considered as tropical, occur in North America (Lewis and
Clarke's Travels, p. 221), in the same high latitude as here,
namely, in both cases, in 47 degs.
[10] These insects were not uncommon beneath stones. I found
one cannibal scorpion quietly devouring another.

[12] I have lately heard that Capt. Sulivan, R.N., has found
numerous fossil bones, embedded in regular strata, on the banks
of the R. Gallegos, in lat. 51 degs. 4'. Some of the bones
are large; others are small, and appear to have belonged to
an armadillo. This is a most interesting and important
discovery.

in his Principles of Geology.

APRIL 13, 1834. - The Beagle anchored within the mouth of the
Santa Cruz. This river is situated about sixty miles south of
Port St. Julian. During the last voyage Captain Stokes proceeded
thirty miles up it, but then, from the want of provisions, was
obliged to return. Excepting what was discovered at that time,
scarcely anything was known about this large river. Captain Fitz
Roy now determined to follow its course as far as time would
allow. On the 18th three whale-boats started, carrying three
weeks' provisions; and the party consisted of twenty-five
souls - a force which would have been sufficient to have
defied a host of Indians. With a strong flood-tide and a fine
day we made a good run, soon drank some of the fresh water,
and were at night nearly above the tidal influence.
The river here assumed a size and appearance which, even at
the highest point we ultimately reached, was scarcely
diminished.
