The same treatment is to be observed with moon
light as with sunlight. You will obtain similar re-
suits, though in some respects they will be re-
versed. glass tube held by sensitive person in
full moonlight will give not cool but lukewarm
sensations. glass Of water that has stood in the
moonlight will be more tepd and unpleasant than
one that has stood for the same time in the shade.
fou are now inpatient to learn what this is, and
where in natural philosophy and physiology these
phenomena are to be classed. They are not eff
fects of heat, though they produce sensations like
those OF warmth and GOODNESS for there is, in crys-
tails, at least, no source of warmth, and if there
were, non-sensitiye persons would perceive it as
well as sensitive, it would certainly affect fine
thermometer They are not electricity, for in
crystals there is no exciting for the constant
currents which here flow forth an electrometer is
not affected and an attempt to apply conductor,
according to electrical laws has no result. 1t is
neither magnetism nor damagnetism because crys-
tails are not magnetic, and damagnetism does not
act in the same way in all crystals, but in very diff
ferent and opposing ways, which here is not the
case. 1t cannot be ordinary light because that
never produces the sensations of tepidty and
GOODNESS.
Equally curious arc the experiments in connec-
ton with terrestrial magnetism. Lay an ordinary
magnet across the corner of table, so that the
two ends will project then place the table that
the magnet will lie in the meridian, with its north
pole to the north, and rice rersa sensitive per-
son will perceive with the palm Of the left hand a
cool current flowing from the north pole and
walmish one fiom the south Glasses Of water
placed near the poles will be affected just as if
placed in the reflected or transmitted sun light So
ALSO in complete darkness, magnets exhibit odylc
light to the eyes of sensitive persons. The light
from the north pole of a magnet is blue-from the
south pole, red and yellow. BY holding the mag
net vertically with the south pole up, the light in
creases if the magnet is strong enough, it rises to
the ceiling so that the sensitive person can dlstin-
gush colors painted there. Or, place large horse
shoe magnet on table, with the two poles up
ward Two distinct flames will be seen rising
from it. Unlike the magnetic currents, they do
not mingle, and neither seems to influence the
other. A magnet of hundred pounds power
gave forth light of great beauty, illuminating
space of six feet on the ceiling objects held close
to the flame cast visible shadow o jects held
over it turned it aside, and blowing it changed its
direction, Just as if it were any other fame with
sun-glass, the light could be collected and con-
densed in a focus. The appearance is, therefore,
altogether corporeal and in many respects like Or
binary fame When two of these flames are
brought together, they do not mingle, but pene-
trate each other the stronger divides the weaker,
which reJntes itself after having been thus ira
yersed; the same is the case when a stick is held
in this fame And, just as crystals appear to be
prevailed with this luminous substance, so is it
with the steel of magnets every particle seems to
be in whitsh glow. The same is the case with
electromagnetic.
These phenomena are not magnetic, says Reich
enbach. The carnations from crystal OF the
same weight are much stronger than from mag
net, but the crystal possesses no magnetism We
have then, in these two cases, Od IN connection
with magnetism and without. Therefore Cd must
be regarded as an Independent force, appearing
sometimes in connection with magnetism, just as
it appears in connection with crystals, with the
sunlight, and with other natural phenomena. We
know tho rescmblances of magnetism and electri
Guy, VIC hnOW tiiuI euCh appears III mt'H"eo Svh-
nection with the other, and have come regard
ing them as identical. So it is with light and heat
the one produces the other, and they are always
found together, but we have never been able to
demonstrate the common cause from which both
have their origin. So it is with Cd. We suppose
these dynamic phenomena spring from common
source, but as long as we are unable to demon
strae this unity of their origin, there is nothing
left but to consider them electricity, magnetism,
light, heat, &C., and to treat each as special
group of phenomena And as the nrlltiform Odylic
phenomena can be classified in neither Of these
groups, we must combine them into special
group. That they are inferior either in extent or
importance to none that have already obtained
place in physical science, our author promises to
show hereafter.
