AURA (from the Gr. for “breath” or “breeze”), a term used in old days to denote a supposed ethereal emanation from a volatile substance; applied later to the “electrical aura,” or air-current caused by electrical discharge; in epilepsy (q.v.) to one of its premonitory symptoms; and in spiritualism to a mysterious light associated with the presence of spirit-forms. See also Aureola.
Transcriber's note: A few typographical errors have been corrected. They appear in the text like this, and the explanation will appear when the mouse pointer is moved over the marked passage. Sections in Greek will yield a transliteration when the pointer is moved over them, and words using diacritic characters in the Latin Extended Additional block, which may not display in some fonts or browsers, will display an unaccented version.
