Its adherents appear to have imbibed their notions from the Arabians,
and claimed the possession of the philosopher's stone, the art of

SYLPHS AND GNOMES, SALAMANDERS AND UNDINES.

eyes are invisible, but were familiarly known to the initiated. To be
admitted to their acquaintance it was previously necessary that the
organs of human sight should be purged by the universal medicine, and
that certain glass globes should be chemically prepared with one or
other of the four elements, and for one month exposed to the beams of
the sun. These preliminary steps being taken, the initiated
immediately had a sight of innumerable beings of a luminous substance,
but of thin and evanescent structure, that people the elements on all
sides of us. Those who inhabited the air were called Sylphs; and those
who dwelt in the earth bore the name of Gnomes; such as peopled the
fire were Salamanders; and those who made their home in the waters
were Undines. Each class appears to have had an extensive power in the
