SYLPH, n.

An immaterial but visible being that inhabited the air when the air was an element and before it was fatally polluted with factory smoke, sewer gas and similar products of civilization. Sylphs were allied to gnomes, nymphs and salamanders, which dwelt, respectively, in earth, water and fire, all now insalubrious. Sylphs, like fowls of the air, were male and female, to no purpose, apparently, for if they had progeny they must have nested in accessible places, none of the chicks having ever been seen.
