When it is wished to produce different colours in the flower other electricities are used, with or without those producing variety of form.  The electricities for producing colours are contained in small pouches, as many in number as the colours we desire to produce.  Then, being placed together at the base of the flower-pot, each on the particular part of the “flower form” which is to be affected, their orifices are opened and the contents of each one are instantaneously emitted.

Most plants are susceptible of every variety of colour; 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.
