Page 242 - Appals the gazing mourner's heart, As if to him it could impart The doom he dreads, yet dwells upon ; Yes, but for these, and these alone, Some moments, ay, one treacherous hour, He still might doubt the tyrant's power ; So fair, so calm, so softly sealed, The first, last look by death revealed!
Page 306 - ... he could form no judgment of their shape, or guess what it •was in any object that was pleasing to him. He knew not the shape of anything, nor any one thing from another, however different in shape or magnitude : but upon being told what things were, whose form he before knew from feeling, he would carefully observe, that he might know them again...
Page 355 - Its strength, even before it was half grown, was great. It would drag along a large sweeping-brush, or a warming-pan, grasping the handle with its teeth so that the load came over its shoulder, and advancing...
Page 221 - There is no other source of knowledge, but a sense of the degree of exertion in his muscular frame, by which a man can know the position of his body and limbs, while he has no point of vision to direct his efforts, or the contact of any external body. In truth, we stand by so fine an exercise of this power, and the muscles are, from habit, directed with so much precision and with an effort so slight, that we do not know how we stand. But if we attempt to walk on a narrow ledge, or stand in a situation...
Page 242 - He who hath bent him o'er the dead Ere the first day of death is fled, The first dark day of nothingness, The last of danger and distress (Before Decay's effacing fingers Have swept the lines where beauty lingers,) And mark'd the mild angelic air, The rapture of repose that's there, The...
Page 305 - When he first saw, he was so far from making any judgment about distances, that he thought all objects whatever touched his eyes (as he expressed it), as what he felt did his skin ; and thought no objects so agreeable as those which were smooth and regular, though he could form no judgment of their shape, or guess what it was in any object that was pleasing to him.
Page 81 - The dark blood is received from all parts of the body by the vence cavce — from the parts above by the descending cava, and from the parts below by the ascending cava. These veins pour the blood into the right auricle. From this it passes into the right ventricle, which sends it by the pulmonary artery to the lungs. From the lungs it returns by the pulmonary veins to the left auricle. It then passes into the left ventricle, from which it is sent by the aorta to all parts of the body.
Page 306 - At first he could bear but very little light, and the things he saw he thought extremely large, but upon seeing things larger, those first seen he conceived less, never being able to imagine any lines beyond the bounds he saw ; the room he was in, he said, he knew to be but part of the house, yet he could not conceive that the whole house could be bigger.

Page ix - Learn to make a right use of your eyes : the commonest things are worth looking at — even stones and weeds, and the most familiar animals.
