Perhaps you will wonder how it is that if we have a weight of 15 lbs. pressing on every square inch of our bodies, it does not crush us. And, indeed, it amounts on the whole to a weight of about 15 tons upon the body of a grown man. It would crush us if it were not that there are gases and fluids inside our bodies which press outwards and balance the weight so that we do not feel it at all.
The long gun enables the pressure of the gases formed by the burning powder to act longer on the shot, with the result that a higher velocity is given to it, not only increasing its range, but also its penetrative power. The result of these improvements was to some extent a repetition of what had taken place when rifled guns were first introduced.
For he had, most completely, subdued what threatened to be a great fire, and when the last of his bombs had been dropped, so effective was the blanket of fire-dampening gases spread around that the flames just naturally expired, as it were.
"Oh, how dared they!" she went on. "The beasts! Tell me, are you ill?" "Weak as a kitten," he faltered. "They've poisoned me with their beastly gases." Catherine rose to her feet. She faced the two men, her eyes flashing with anger. "The Council will require an explanation of this, Mr. Fenn!" she declared passionately. "Barely an hour ago you told us that Mr. Orden had escaped from Hampstead."
I was wearing a mask of my own invention, a thing that covered ears and head and everything, something like a diver's helmet I was dealing with gases a sniff of which meant death; only a few days before, unmasked, I had been doing some fool's trick with a couple of acids sulphuric and cyanide of potassium when, somehow, my hand slipped, and, before I knew it, minute portions of them combined.
They were big ones, of the kind used for commercial gases like propane or oxygen." "Or hydrogen?" Scotty asked quickly. "Or hydrogen," Steve agreed. "And that's probably what they contain, for inflating the balloons." He got up, turned off the coffee, and poured three cups. "Along about that time, I heard rifleshots. You can imagine what I thought.
"Now, the drains being out of sight, it is morally certain that defects will exist, or be caused by wear and tear, unseen. In one place evil liquids and gases will percolate; in another evil accumulations will putrefy.
Not with shout and cheer did it rush forward, nor yet with venomous gases that gave the alarm, that choked, that strangled, that tortured. Silence and concealment, and the invisible blight of sleep, like the greater numbing that once fell on the hosts of Sennacherib, enfolded all opposition.
Before the blow could fall, the furnace flare blazed aloft like a mighty torch, and the man grounded his weapon. "I beg your pardon, Mr. Gordon; I I took ye for somebody else," he stammered; and Tom scanned his face sharply by the light of the burning gases. "Whom? for instance," he queried. "Why-e-yeh I reckon it don't make any diff'rence my tellin' you; you'd ought to have it in for him, too.
He then prepared some pure oxygen and nitrogen gases, and passed them by means of a tube going from the outside of the vessel, up through the mercury into the infusion; so that he thus had it exposed to a perfectly pure atmosphere of the same constituents as the external air.
