n its tube. I
thought, at first, that this was the result of accident, but when the
creature again elevated itself, and again captured a starch grain, I was
compelled to admit design!
By some sense, it had discovered the presence of starch, which it
recognized to be food; it could not get at this food without making a
change in its position, which, therefore, it immediately proceeded to
do!
Here was an act which required, so it seemed to me, correlative
ideation, and which was doubly surprising, because occurring in an
animal of such extremely simple organization. This observation was
substantiated, however, by the testimony of Professor Carter, an English
biologist, which came to my notice a week or so thereafter. This
investigator witnessed a similar act in an animalcule belonging, it is
true, to another family, but which is almost, if not quite, as simple in
its organization as Stentor. He does not designate the particular
rhizopods that he had under observation, yet from his language, we are
able to classify them approximately. His account is so very interesting
that I take the liberty of quoting him in full.
"On one occasion, while investigating the nature of some large,
transparent, spore-like elliptical cells (fungal?) whose protoplasm was
rotating, while it was at the same time charged with triangular grains
of starch, I observed some actinophorous rhizopods creeping about them,
which had similar shaped grains of starch in their interior; and having
determined the nature of these grains by the addition of iodine, I
cleansed the glasses, and placed under the microscope a new portion of
the sediment from the basin containing these cells and actinophryans for
further examination, when I observed one of the spore-like cells had
become ruptured, and that a portion of its protoplasm, charged with the
triangular starch grains, was slightly protruding through the crevice.
It then struck me that the actinophryans had obtained their starch
grains from this source; and while looking at the ruptured cell, an
_actinophrys_ made its appearance, and creeping round the cell, at last
arrived at the crevice, from which it extricated one of the grains of
starch mentioned, and then crept off to a good distance. Presently,
however, it returned to the same cell; and although there were now no
more starch grains protruding, the _actinophrys_ managed again to
extract one from the interior through the crevice. All this was repeate
