Стр. 322 - Choosing a place where the water deepens gradually, walk coolly into it till it is up to your breast, then turn round, your face to the shore, and throw an egg into the water between you and the shore.
Стр. 322 - To encourage yourself in order to do this, reflect that your progress will be from deeper to shallower water, and that at any time you may, by bringing your legs under you, and standing on the bottom, raise your head far above the water.
Стр. 322 - ... that you cannot but by active force get down to the egg. Thus you feel the power of the water to support you, and learn to confide in that power; while your endeavours to overcome it, and...
Стр. 327 - If he moves his hands under the water in any way he pleases, his head will rise so high as to allow him free liberty to breathe ; and if he...
Стр. 411 - ... moisture to the plant, whilst young, is thus deprived of proper nutriment, and, ceasing almost wholly to grow, becomes of no importance to the tree. The tap root of the oak, about which so much has been written, will possibly be adduced as an exception; but having attentively examined at least 20,000 trees of this species, many of which had grown in some of the deepest and most favourable soils of England, and never having found a single tree possessing a tap root, I must be allowed to doubt...
Стр. 83 - In air and vapours this force appears to act uncontrolled ; but in liquids it is overcome by a cohesive force, while the particles still retain a power of moving freely in all directions It is simplest to suppose the force of cohesion nearly or perfectly constant in its magnitude, throughout the minute distance to which it extends, and owing its apparent diversity to the contrary action of the repulsive force which varies with the distance.
Стр. 337 - ... cliff, as well as the representation of a windmill near at hand. The reflected images were most distinct precisely opposite to where we stood, and the false cliff seemed to fade away, and to draw near to the real one, in proportion as it receded towards the west. This phenomenon lasted about ten minutes, till the sun had risen nearly his own diameter above the sea. The whole then seemed to be elevated into the air, and successively disappeared, like the drawing up of a drop scene in a theatre.
Стр. 336 - Walking on the cliff" about a mile to the east of Brighton, on the morning of the 18th of November 1804, while watching the rising of the sun, I turned my eyes directly...
Стр. 409 - ... thus occasions an increased longitudinal extension of the substance of the new wood on that side.* The depression of the lateral branch is thus prevented ; and it is even enabled to raise itself above its natural level, when the branches above it are removed ; and the young tree, by the same means, becomes more upright, in direct opposition to the immediate action of gravitation : nature, as usual, executing the most important operations by the most simple means. I could adduce many more facts...
Стр. 263 - ... a sieve. The feathers should be afterwards well washed in clean water, and dried upon nets, the meshes of which may be about the fineness of cabbage-nets. The feathers must be from time to time shaken upon the nets, and as they dry will fall through the meshes, and are to be collected for use.
