Definition

These gradations of matter increase in rarity or fineness, until we arrive at a matter unparticled—without particles—indivisible—one; and here the law of impulsion and permeation is modified. — The Works of Edgar Allan Poe, The Raven Edition: Table Of Contents And Index Of The Five Volumes, Edgar Allan Poe
In carrying out his plan he had constructed a monster balloon capable of floating in the air thirty days, due allowance being made for the daily escape of gas by permeation through the envelope. — Wealth of the World's Waste Places and Oceania, Jewett C. (Jewett Castello) Gilson
Now, if some bold novelist, tearing aside the cleverly woven curtain of our conventional ego, shows us under this appearance of logic a fundamental absurdity, under this juxtaposition of simple states an infinite permeation of a thousand different impressions which have already ceased to exist the instant they are named, we commend him for having known us better than we knew ourselves. — Time and Free Will: An Essay on the Immediate Data of Consciousness, Henri Bergson
