126 ÆäÀÌÁö - The days of our age are three score years and ten; and though men be so strong, that they come to four score years; yet is their strength then but labour and sorrow; so soon passeth it away, and we are gone.
370 ÆäÀÌÁö - What — the blude and stomach ? NORTH. Just so, James. Apparitions are likewise considered by him as nothing more than ideas, or the recollected images of the mind, which have been rendered more vivid than actual impressions.
182 ÆäÀÌÁö - ... surface became elevated into a small cone above each of the wires ; waves flowed off in all directions from these cones ; and the only point of rest was apparently where they met in the centre of the mercury between the two wires. On holding the pole of a powerful...
297 ÆäÀÌÁö - In 283 common with the inhabitants of Koonawur, the greater part of them have a flint and steel for striking fire, attached to their apparel by a metal chain. The women, whose dress resembles that of the men, were literally groaning under a load of ornaments, which are mostly of iron or brass, inlaid with silver or tin, and beads round their necks, wrists, and ankles, and affixed to almost every part of their clothes.
270 ÆäÀÌÁö - Thus intrenched and secure, 33 men may be made to carry on an excavation which is 630 feet superficial area, in regular order and uniform quantities, with as much facility and safety as if one drift only of 19 feet square was to be opened by one man. The drift Carried under the Thames in 1809, which was...
357 ÆäÀÌÁö - Exeter Change was only to excite his attention, which was very great. He remained silent and motionless. But no sooner were the flat notes sounded, than he sprang up, attempted to break loose, lashed his tail, and seemed so furious and enraged as to frighten the female spectators. This was attended with the deepest yells, which ceased with the music. Sir E. Home has found this inequality of the fibres in neat-cattle, the horse, deer, the hare, and the cat.
357 ÆäÀÌÁö - Boncourt, having its broad base resting on the ground, and its summit lost in the clouds. It consisted of a thick and blackish vapour, in the middle of which were often seen flames in several directions. .Advancing along with the storm, it broke or tore up by the roots, in the space of a league, seven or eight hundred trees of different sizes, and at last burst with great violence in the village of Marchepoy, one half of the houses of which were instantly destroyed. The...
371 ÆäÀÌÁö - In the succeeding, and by far the most considerable part of this treatise, the research is of a novel kind. Since apparitions are ideas equalling or exceeding in vividness actual impressions, there ought to be some important and definite laws of the mind which have given rise to this undue degree of vividness. " It is therefore chiefly for the purpose of explaining such laws, that the present dissertation is written. But I here enter into a perfectly new field of research, where far greater difficulties...
269 ÆäÀÌÁö - ... over the second very much sunk, the undertaking was abandoned. The character of the plan before us consists in the mode of effecting the excavation, by removing no more earth than is to be replaced by the body of the tunnel, retaining thereby the surrounding ground in its natural state of density and solidity.
370 ÆäÀÌÁö - February 1823, at 1" lO' p. M., in E. Long. 85¡Æ 33', and N. Lat. 52¡Æ, experienced a shock similar to that of an earthquake. A tremulous motion of the vessel, as if it were passing over a coral rock, alarmed all on board, and this was accompanied with a loud rumbling noise, both of which continued two or three minutes. As the ship was going only...
