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
