[Footnote 1: It was not till a later date that gases were employed, the effects of which were increased by rain.

As the foul vapours of the mine and the manufactory destroy vegetation and injure health, so does the Nemesis fall on the world of man; so does that human soot, these human poison gases, infect the whole society which has allowed them to fester under its feet.

Every leaf which drops from the bough, to return again into its gases and its dust, is working out chemical problems which have puzzled a Boyle and a Lavoisier, and about which a Liebig and a Faraday will now tell you that they have but some dim guess, and that they stand upon the threshold of knowledge like (as Newton said of himself) children gathering a few pebbles, upon the shore of an illimitable sea.

He knew that, with the shaft crowded full of wreckage and giving no passage to the air, the entire mine would eventually become filled with poisonous gases.

The poisonous gases must still be entering through the crevices of his imperfectly built and rudely plastered wall, and it would be wise for him to get farther away.

The mine soon fills with poisonous gases when the air supply is cut off.

The only condition absolutely necessary to the purification of the blood is an organ having a delicate membrane, on one side of which is a thin sheet of blood, while the other side is in such contact with the air that an interchange of gases can readily take place.

As a result, a diffusion of gases ensues.

On the contrary, it should be changed oftener than cotton, or even linen, because it will absorb a great deal of fluid, especially the matter of perspiration, which, if long retained, is believed to ferment, and produce unhealthy, if not poisonous gases.

But no gases necessary to health are evolved during the decomposition of vegetable matter; on the contrary, it is well known that many of them tend to induce disease.

They seem, somehow, to be fully persuaded that the inspired word of God has no inherent power to stand alone,that it has fallen among thieves and robbers,is being pelted with fossil coprolites, suffocated with fire-mist and primitive gases, or beaten over the head with the shank-bones of Silurian monsters, and is bawling aloud for assistance.

The heat furnished by the gas flame is so well absorbed by radiation from the radiator rings that the gases, on making their exit, have no longer a temperature of more than from 35 to 40 degrees.

The water due to the condensation of the gases is led through a small pipe out of doors or into a vessel from whence it may evaporate anew, so as not to change the hygrometric state of the air.

When nicotine vapor is passed through a red-hot tube, it yields essentially collidine, and, with this, some pyridine, picoline, lutidine, and gases such as hydrogen, marsh-gas, and ethylene.

HAGGARD, HOWARD W. Noxious gases and the principles of respiration influencing their action.

An Introduction to thermodynamics, the kinetic theory of gases and statistical mechanics.

Gas tables; thermodynamic properties of air, products of combustion and component gases, compressible flow functions, including those of Ascher H. Shapiro and Gilbert M. Edelman.

Solids, at certain temperatures, are converted into liquids; and liquids, in like manner, when heated to certain degrees, become aeriform fluids or gases.

The lights are caused by certain gases that come from the marshy ground and glow when the atmosphere is in a certain condition.

The ventilation of the kitchen should be so ample as to thoroughly remove all gases and odors, which, together with steam from boiling and other cooking processes, generally invade and render to some degree unhealthful every other portion of the house.

This is of the utmost importance, since the germs and foul gases arising from decomposing food stuffs form a deadly source of contamination through every crack and crevice.

An elastic fluid, now known as the photosphere, is in course of continual formation on the dark rugged surface of the solar mass; and rising, on account of its specific lightness, it forms the pores in the stratum of reflecting clouds; then, combining with other gases, it produces the irregularities or furrows in the luminous cloud-region.

" ESPY, JAMES POLLARD, a meteorologist, born in Pennsylvania; did notable work in investigating the causes of storms, and in 1841 published "The Philosophy of Storms"; was appointed to the Washington observatory, where he carried on experiments in the cooling of gases and atmospheric expansion (1785-1860).

The nose records the chemical touch of the gases or fine particles of material which touch its mucous membrane.

It is finer and more subtle that the rarest vapors or gases known to science.

Outside of the thronged streets; away from piled up bricks and mortar; outside of the clank of machinery; the rumbling of carriages; the roar of the escape pipe; the scream of the steam whistle; the tramp, tramp of moving thousands on the stone sidewalks; away from the heated atmosphere of the city, loaded with the smoke and dust, and gasses of furnaces, and the ten thousand manufactories of villainous smells.

We cannot speak with perfect certainty here, as all the factors that might be of influence upon the distribution of density in a sun atmosphere are not well enough known, but we can surely demonstrate that in case one of the gasses with which we are acquainted were held in equilibrium solely by the influence of attraction of the sun the phenomenon should become much less as soon as we got somewhat further from the edge of the sun.

For a time our efforts seem to create, and to adorn, and to perfect, until we forget our origin and destination, substituting self for that divine hand which alone can unite the elements of worlds as they float in gasses, equally from His mysterious laboratory, and scatter them again into thin air when the works of His hand cease to find favour in His view.

If the singular cannot now be written gass, the plural should nevertheless be gasses, and the adjective should be gasseous, according to Rule 3d.

"The spark will pass through the interrupted space between the two wires, and explode the gasses.

"Do we sound gasses and gasseous like cases and caseous?

"Gas forms the plural regularly, gasses.

"Singular, gas; Plural, gasses."Clark cor.

Louis and Clark, the very men I'd read about in Gasses Journal, how I wished their eyes could see and their ears hear me.
