159. EVERY person who feels, in any degree what-
ever, the influence of the spirits, is a medium. This
faculty is inherent in man, and consequently not an
exclusive privilege ; so there are few in whom are not
found some rudiments of it.
It might thus be said that very nearly every one is
a medium. Usually, this qualification is applied only
to those in whom the medianimic faculty is clearly
characterized, and shown by visible effects of a certain
intensity, which depends on an organization more or
less sensitive. It must be remarked that this faculty
is not revealed in the same manner with all; mediums,
usually, have a special aptitude for such or such order
of phenomena, which makes as many varieties as
there are kinds of manifestations. The principal are,
mediums for physical effects; sensitive or impressible
mediums; auditive ; speaking; seeing; somnambulis-
tic; healing; pneumatographic ; writing or psychographic.
