It must, however, be remembered that they also come from rain-water, and that in hilly or broken regions the source of that rain water may be the surface of the ground only a few hundred yards up the hill or mountain, and impurities there may affect it.

In the rainy season this should be filtered, as it brings down many impurities from the torrents of Abyssinia, but in the heat of summer the river is entirely dry, and clear and wholesome water is procured from wells in the sandy bed.

Still there was something about the man which seemed to sweep away unbelief and cynicism and petty distrust, as the bright mountain freshet sweeps away the wretched little mud puddles and the dust and impurities from the bed of a half dry stream.

The combined area of these passageways being less than that of the conduit, F, from the receiving chamber, the metal is skimmed of impurities, and the latter are retained in the receiving chamber, E. The entering metal flows first to the lower hub part at H H, thence by the sprue-ways, G G, to the lower rim part at J J, being again skimmed at the mouth of the sprue-ways.

When coal gas was first employed during the early part of this century as an illuminating agent, the low pitch of the old fashioned rooms, and the excess of impurities in the gas, rendered it imperative that the products of combustion of the sulphur-laden gas should be conducted from the apartment, and for this purpose arrangements of tubes with funnel shaped openings were suspended over the burners.

Two grains of quicksilver laid upon a polished surface will never unite if their surfaces be dusted over with minute impurities, or if the surface of one of them be. Clean away the motes, and they will coalesce and be one. A film of sin separates men from God. And if the film be removed the man dwells in God, and God in him.

Darcy would no more suffer him to call on Jane in such a part of London! My dear aunt, how could you think of it? Mr. Darcy may perhaps have heard of such a place as Gracechurch Street, but he would hardly think a month's ablution enough to cleanse him from its impurities, were he once to enter it; and depend upon it, Mr. Bingley never stirs without him." "So much the better.

We were kept free from the stains and impurities which might have remained upon us had we been travelling with the crowd of less imaginative malcontents through the dark lanes and foul by-roads of ordinary fanaticism." Pantisocracy was indeed a happy episode for English literature.

Where not necessary to secure the insects alive, we sprinkle over the attractive plant-beds a strong poison, which is itself extracted from insects. There are at times certain impurities in places very difficult of access. Swarms of insects, secured in immense cages, are brought as near as can be to the spot.

The breath is loaded with carbonic acid and other impurities; the perspiration is loaded with all that makes it differ from pure water; the urine, especially, is loaded with waste separated from the blood and tissues of the body. The space, so to speak, left vacant by all this washing away of waste matter makes its emptiness felt by a call upon the stomach to furnish fresh material.
