309 ÆäÀÌÁö - ... or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern. Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
33 ÆäÀÌÁö - All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.
247 ÆäÀÌÁö - But, whatever criticisms might be justified by the ambitious title of "the Association for the Reform and Codification of the Laws of Nations...
310 ÆäÀÌÁö - I'll show you sir. It is an automa runs under water with a snug nose and has a nimble tail, made like an auger, with which tail she wriggles betwixt the costs (ribs) of a ship, and sinks it straight.
75 ÆäÀÌÁö - On the whole we may fairly conclude that, whilst there is some evidence of a tidal yielding of the earth's mass, that yielding is certainly small, and the effective rigidity is at least as great as that of steel.
310 ÆäÀÌÁö - They have likewise discovered two lesser stars, or satellites, which revolve about Mars, whereof the innermost is distant from the center of the primary planet exactly three of his diameters, and the outermost five; the former revolves in the space of ten hours, and the latter in twenty-one and a half...

With descriptions of Voltaic Batteries, Magneto and Dynamo-Electric Machines, Thermopiles, and of the Materials and Processes used in every Department of the Art, and several Chapters on Electro-Metallurgy. By ALEXANDER WATT, Author of " Electro-Metallurgy,
256 ÆäÀÌÁö - Engineers, The American Society of Mechanical Engineers, and the American Institute of Electrical Engineers.
188 ÆäÀÌÁö - That the conference expresses the hope that, as soon as may be practicable, the astronomical and nautical days will be arranged everywhere to begin at mean midnight 7.
414 ÆäÀÌÁö - October, 1884, for the purpose of discussing, and, if possible, fixing upon a meridian proper to be employed as a common zero of longitude and standard of time-reckoning throughout the whole world...
