our; thus are
produced roses, pink, blue, green, lilac, brown, fire-colour, and
sun-colour, which last is a colour so brilliant that the eye that has
long gazed upon it stands in need of repose.

Amongst the electricities for giving colours is sun electricity,
received in different ways. Again, the electricities of some birds give
lovely colours; and so does that of the gold-fish. Moss gives a colour
resembling fire-sparks. Frogs produce a beautiful violet.

Where the flowers and leaves have not a decided perfume of their own, we
can give a beautiful fragrance to either, though not to both on the same
plant. To produce this result, we inoculate the plant with certain
fragrant gases. Our dahlias, unlike yours, yield a highly fragrant and
delightful perfume.

The plants treated by us in these ways are fitly called flowers,
presenting as they do a mass of blossoms and exhaling delicious
perfumes. They act, mediately or immediately, on the concentrated light
of the organization through the nerves of smell, as beautiful sounds
through the medium of the ear, or as beautifully harmonised colours
through the eye. You will recollect that a modification of concentrated
light is supposed to be the link through which the soul communicates its
impressions to the brain, on whose divisions it is made to act in
electric forms.

Besides an infinite variety of flowers, we produce every variety of
colour and perfume in the leaves of the evergreens which adorn our
streets and habitations, emitting healthy and refreshing fragrance,
increased by every movement of the wind.

CREATION OF FORMS.

Not wholly unconnected with this subject is the creation of electric
forms for amusement at a distance from the operator. This is effected by
the aid of tubes made from the membranes covering the eyes of birds,
which are invisible to the naked eye even when at a short distance from
the observer.

In the mouth of one of these tubes, which spreads out slightly, is
placed a small form made of grains of powder obtained from the coloured
seeds of flowers, and, a bag of electricity being applied, the fluid
rushes through the tube. Instantly, at the other end, appears the figure
or form traced at the mouth, but of ordinary or gigantic stature,
proportioned to the power or quantity of electricity employed.

The forms can be varied or changed at will, and have so li
