Page 190 - Kentucky, are blind. In some of the crabs the footstalk for the eye remains, though the eye is gone; — the stand for the telescope is there, though the telescope with its glasses has been lost. As it is difficult to imagine that eyes, though useless, could be in any way injurious to animals living in darkness, their loss may be attributed to disuse.
Page 210 - When an insect alights on the central disc, it is instantly entangled by the viscid secretion, and the surrounding tentacles after a time begin to bend, and ultimately clasp it on all sides. Insects are generally killed, according to Dr. Nitschke, in about a quarter of an hour, owing to their tracheae being closed by the secretion. If an insect adheres to only a few of the glands of the exterior tentacles, these soon become inflected and carry their prey to the tentacles next succeeding...
Page 86 - all the exhilarating emotions the eyebrows, eyelids, " the nostrils, and the angles of the mouth are raised. " In the depressing passions it is the reverse.
Page 194 - If an insect adheres to only a few of the glands of the exterior tentacles, these soon become inflected, and carry their prey to the tentacles next succeeding them inwards ; these then bend inwards, and so onwards until the insect is ultimately carried, by a curious sort of rolling movement, to the centre of the leaf.
Page 209 - ... whole upper surface is covered with gland-bearing filaments, or tentacles, as I shall call them, from their manner of acting. The glands were counted on thirtyone leaves, but many of these were of unusually large size, and the average number was 192 ; the greatest number being 260, and the least 130. The glands are each surrounded by large drops of extremely viscid secretion, which, glittering in the sun, have given rise to the plant's poetical name of the sun-dew.
Page 114 - ... and closing of the eyelids; altered respiratory movements causing screaming, flushing of the face, and, finally, action spreading to all parts of the body, the boy cries, stamps, the fists are clenched and he hits out. This augmenting series of acts is produced by an increasing area of brain in action — no wonder that such a storm among the nerve-cells is followed by the signs of exhaustion. Such series of movements may occur, sequential to some stimulus, the final movement being much stronger...
Page 86 - ... the feeling depends in all cases on the strength of the appetence, and on the degree to which it is gratified or thwarted. The phrases, joyful and sorrowful, may be applied to all the feelings falling under the head of the immediate. Let us follow them from their weaker to their stronger forms. " In joy the eyebrow is raised moderately but without any angularity, the forehead is smooth, the eye full, lively, and sparkling, the nostril is moderately inflated, and a smile is on the lips. In all...
Page 138 - Training as training in thought-expression by other means than gesture and verbal language, in such a carefully graded course of study as shall also provide adequate training for the judgment and the executive faculty.
Page 87 - From the shaking of the body, the head nods to and fro. The lower jaw often quivers up and down, as is likewise the case with some species of baboons, when they are much pleased. During laughter the mouth is opened more or less widely, with the corners drawn much backwards, as well as a little upwards; and the upper lip is somewhat raised. The drawing back of the corners is best seen in moderate laughter, and especially in a broad smile — the latter epithet showing how the mouth is widened, . ....
Page 180 - The style, now flabby, has fallen upon the front lobe, its stigma dry, and no longer receptive ; the now opening anthers are brought upward and forward to the position which the stigma occupied before. A honey-bee, taking nectar from the bottom of the corolla, will be dusted with pollen from the later flower, and on passing to one in the earlier state will deposit some of it on its fresh stigma. Self-fertilization here can hardly ever take place, and only through some disturbance of the natural course.
