Стр. 12 - And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth : and it was so.
Стр. 12 - And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind : and God saw that it was good. And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth.
Стр. 11 - THE assignation of particular names to denote particular objects, that is, the institution of nouns substantive, would, probably be one of the ' first steps towards the formation of language. Two savages, who had never been taught to speak, but had been bred up remote from the societies of men, would naturally begin to form that language by which they would endeavour to make their mutual wants intelligible to each other, by uttering certain sounds, whenever they meant to denote certain...
Стр. 394 - It is this: — when a small battery is moderately excited by diluted acid and its poles (which should be terminated by cups of mercury) are connected by a copper wire not more than a foot in length, no spark is perceived when the connection is either formed or broken : but if a wire thirty or forty feet long be used (instead of the short wire), though no spark will be perceptible when the connection is made, yet when it is broken by drawing one end of the wire from its cup of mercury, a vivid spark...
Стр. 394 - Annals of Philosophy that I have been anticipated in this experiment of drawing sparks from the magnet by Mr. James D. Forbes of Edinburgh, who obtained a spark on the 30th of March; my experiments being made during the last two weeks of June. A simple notification of his result is given, without any account of the experiment, which is reserved for a communication to the Royal Society of Edinburgh ; my result is therefore entirely independent of his and was undoubtedly obtained by a different process.
Стр. 4 - Hitchcock, in liis report of a geological survey of Massachusetts, makes the following remarks in relation to the effect of iron upon a soil : " No ore except iron occurs in sufficient quantity in the state to deserve notice in an agricultural point of view. In the west part of Worcester county, the soil for a width of several miles across the whole state, is so highly impregnated with the oxide of iron, as to receive from it a very deep tinge of what is called iron rust. This is particularly the...
Стр. 22 - It yields both the precious and common varieties. There is another bed in the same town, associated with steatite or soapstone. In the west part of Westfield is found another extensive bed of this rock, extending into Russell, of a much darker color, and containing green talc. This has been used in a few instances for ornamental architecture, and has a rich appearance when wrought.
Стр. 85 - It is not monopolized by any one, but is carried away freely by all who care to collect it, and for this purpose the spring is frequently visited. I could not ascertain how much is annually obtained. But the quantity is considerable. It is said to rise more abundantly in hot weather than in cold. Gas is constantly escaping through the water, and appears in bubbles upon its surface.
Стр. 390 - Feb. 17. Mr. Faraday gave an account of the first two parts of his researches in electricity ; namely voltaelectric induction, and magneto-electric induction. . . . If a wire connected at both extremities with a galvanometer, be coiled in the form of a helix around a magnet, no current of electricity takes place in it. This is an experiment which has been made by various persons hundreds of times, in the hope of evolving electricity from magnetism. But if the magnet be withdrawn from or introduced...
Стр. 390 - No detail is given of the experiments, and it is somewhat surprising that results so interesting, and which certainly form a new era in the history of electricity and magnetism, should not have been more fully described before this time in some of the English publications. The only mention I have found of them is the following short account from the Annals of Philosophy for April, under the head of Proceedings of the Royal Institution :
