NOTE.
(See page 13, vol. i.)
A method has since been mentioned to me, by which the colours of the flowers of plants are well preserved. The process was this:—The paper being first heated before the fire, or in an oven, the plant recently gathered is placed between the hot sheets, and pressed. It is requisite, however, that the paper, in the same heated state, be renewed at intervals, on account of the expressed juices from the stalks and leaves fermenting, which might otherwise injure the plants.
There is also a method of preserving plants in flower, by which their natural form, as well as colours, can be preserved. It consists in placing the plant in a jar, and pouring fine sand upon it, until the whole plant is covered: it is then to be placed, still kept in the jar, into an oven; after which, being taken out, and the sand removed, the plant is found preserved both in its form and colour.
