from The Century Dictionary and Cyclopedia
- adj. Producing clouds (of tobacco-smoke).
We shall sleep well to-night; but let us sit awhile with nubiferous, or, if we may coin a word, nepheligenous accompaniment, such as shall gently narcotize the over-wearied brain and fold its convolutions for slumber like the leaves of a lily at nightfall.
The nepheligenous flying discs are argentiferous space ships from other worlds in space.
This word comes from the Greek 'nephos,' cloud.
