Page 31 - And they placed them on the heavenly tablets, each had thirteen weeks; from one to another (passed) their memorial, from the first to the second, and from the second to the third, and from the third to the fourth.
Page 102 - ... 1. The cancelli of such bones as assist in supporting the weight of the body, are arranged either in the direction of that weight, or in such a manner as to support and brace those cancelli which are in that direction. In a mechanical point of view, they may be regarded in nearly all these bones as a series of 'studs
Page 26 - ... must, therefore. bend; but it must have no abrupt or considerable bending at one part, for the spinal marrow within would in this way suffer. By this consideration we perceive why there are twenty-four bones in the spine, each bending a little ; each articulated or making a joint with its fellow ; all yielding in a slight degree, and, consequently, permitting in the whole spine that flexibility necessary to the motions of the body. It is next to be observed, that whilst the spine by this provision...
Page 98 - THE wisest man could ask no more of Fate Than to be simple, modest, manly, true, Safe from the Many, honored by the Few ; To count as naught in World, or Church, or State, But inwardly in secret to be great...
Page 28 - It is prepared to yield in the direction of its curves ; the pressure is of necessity more upon one side of the column than on the other ; and its elasticity is immediately in operation without a jerk. It yields, recoils, and so forms the most perfect spring ; admirably calculated to carry the head without jar, or injury of any kind.
Page 91 - ... some ants carry corn, and some carry their young, and some go empty, and all to and fro a little heap of dust. It taketh away or...
Page 28 - If a steel spring, perfectly straight, be pressed betwixt the hands from its extremities, it will resist, notwithstanding its elasticity, and when it does give way, it will be with a jerk. Such would be the effect on the spine if it stood upright, one bone perpendicular to another ; for then the weight would bear equally ; the spine would yield neither to one side nor to the other ; and, consequently, there would be a resistance from the pressure on all sides being balanced. We, therefore, see the...
Page 86 - ... can be seen in perfection only when the animal machinery has been kept in full activity. In inflammation, and pain, and necessary restraint, they become weak ; and even confinement, and want of exercise, without disease, will produce imperfections. Exercise unfolds the muscular system, producing a full bold outline of the limbs, at the same time that the joints are knit, small, and clean. In the loins, thighs, and legs of a dancer we see the muscular system fully developed ; and when we turn...
Page 93 - On the Wisdom of God manifested in the Works of the Creation," has several chapters on the animal economy.
Page 98 - He widened knowledge and escaped the praise; He wisely taught, because more wise to learn; He toiled for Science, not to draw men's gaze, But for her lore of self-denial stern. That such a man could spring from our decays Fans the soul's nobler faith until it burn.
