Page xiv - None from henceforth shall use to multiply gold or silver, or use the craft of multiplication; and if any the same do, he shall incur the pain of felony.
Page 90 - By his admirable contrivances, it has become a thing stupendous alike for its force and its flexibility, — for the prodigious power which it can exert, and the ease, and precision, and ductility, with which it can be varied, distributed, and applied. The trunk of an elephant that can pick up a pin or rend an oak is as nothing to it.
Page 394 - Possibly they may be of service in supporting the body while you are learning what is called the stroke, or that manner of drawing in and striking out the hands and feet that is necessary to produce progressive motion. But...
Page 394 - ... reach the egg, teach you the manner of acting on the water with your feet and hands, which action is afterwards used in swimming to support your head higher above the water, or to go forward through it...
Page 394 - The practice I mean is this ; chusing 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 ; it will sink to the bottom, and be easily seen there, as your water is clear.

It can engrave a seal, and crush masses of obdurate metal like wax, before it, — draw out, without breaking, a thread as fine as gossamer, and lift a ship of war like a bauble in the air. It can embroider muslin, and forge anchors, — cut steel into ribands, and impel loaded vessels against the fury of the winds and waves.
Page 492 - Brazil wood, with as much alum as it can dissolve, and a little gum, forms a good red ink. These processes consist in forming a lake, and retarding its precipitation by the gum.
Page 396 - ... But, as I said before, I would not advise you or any one to depend on having this presence of mind on such an occasion, but learn fairly to swim ; as I wish all men were taught to do in their youth. They would, on many...
