The filth and stagnant pools of the working-people's quarters in the great cities have, therefore, the worst effect upon the public health, because they produce precisely those gases which engender disease; so, too, the exhalations from contaminated streams. But this is by no means all. The manner in which the great multitude of the poor is treated by society to-day is revolting.
I forgot how I had been sweltering about, and said: "Yes; it is a Saratoga day. It's supposed that the sparkle of the air comes from the healthful gases thrown off by the springs. Some people say the springs are doctored; that's what makes their gases so healthful." "Why, anything might happen here," Kendricks mused, unheedful of me. "What a scene! what a stage!
It will be seen that the writer of this article accepted the existence of water on Mars, on the testimony of Sir W. Huggins, which, in view of later observations, he has himself acknowledged to be valueless. Dr. Johnstone Stoney's proof of its absence, derived from the molecular theory of gases, had not then been made public. Description of some of the Canals. At the end of his volume Mr.
Not only so, but a column of water, some twenty to twenty-five feet in height, is acting like the piston of a pop-gun, and is driving all the accumulated gases charged with the germs of typhoid fever into every house which has communication with the sewers. There is no help for it, the poisonous vapours must be forced out of the drains and must be forced into the houses.
Thus, in the Charleston earthquake of 1883, the surface over an area of many hundred square miles was pitted with small craters, formed by the uprush of water impelled by its contained gases. These little water volcanoes for such we may call them sometimes occur to the number of a dozen or more on each acre of ground in the violently shaken district.
Penn, are merely the result of gases given off by the carcasses during decomposition great air-bubbles, so to speak, in the pasty mass, becoming caverns when the waters receded and the paste hardened to rocky consistency. But these and such-like fanciful views were doomed even in the day of their utterance.
M. Cailletet, having fruitlessly subjected air and hydrogen to a pressure of one thousand atmospheres, came to the conclusion that it was impossible to liquefy those gases at the ordinary temperature by pressure alone.
This process is generally known as disinfection, and is carried out either by baking, boiling, or steaming, or by the use of strongly poisonous fluids or gases, known as disinfectants.
But when he saw the others seeking places of safety from the gases, and possibly fragments that would follow the explosion, and when he stood upon the platform of the derrick which afforded so insecure a foot-hold, because of the oil upon it, his courage failed him.
Sitting down on the ground, they began to eat this manna, which had a delicious flavour and marvellous purity and freshness. "As you doubtless have already suspected," said the spirit, "the basis of this in every case is carbon, combined with nitrogen in its solid form, and with the other gases the atmosphere here contains.
