lectricity, and the mouth of the bag is so arranged as to fit closely
round the form of the metal-flower in such a way that the electricity
has no escape but into the hollow metal block and through its fine,
hollow point. The metal point, previously to its insertion in the root
of the plant, is prepared with a solution to prevent the escape of any
of the electricity through its pores.

As soon as the bag is opened the electricity is attracted into the metal
form, and having no other escape, proceeds instantaneously through the
funnel and through the hair-tube into the plant. In doing this, it
retains the form implanted by its contact with the metal model, and by
the forced passage through which it has become married with another
electricity.

As soon as it is attracted by the solution with which the inside of the
metal is covered, a shock is produced which materially assists the
operation, by causing the electricity to imprint itself with greater
force and certainty on the embryo plant with which you will recollect
the hair-point has been connected.

It is essential that the charge should be sufficiently strong to modify
or overpower the electricity already existing in the plant, in order to
change the form which this would otherwise take; but, at the same time,
care is taken that the charge is not too powerful, for in that case, and
particularly if an antipathetic electricity be employed, the flower
would be instantly killed. The electricity is therefore applied in
gentle proportions at first, and then the operation is repeated several
times.

PRODUCTION OF COLOUR.

It is electricity that, as I have said, gives colour to plants. Their
varied tints depend on the sympathy or attraction of their electricity
to sun and light electricities. Particular parts of the plant, from the
nature of their fibre, have the power to attract larger portions than
others of the colouring electricities.

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 col
