DRACO Volans, in Meteorology, a fiery exhalation, frequent in marshy and cold countries.
It is most common in summer; and though principally seen playing near the banks of rivers, or in boggy places, yet sometimes mounts up to a considerable height in the air, to the no small terror of the amazed beholders: its appearance being that of an oblong, sometimes roundish, fiery body, with a long tail. It is entirely harmless, frequently flicking to the hands and clothes of people without injuring them in the least.
