Plants are organic bodies^ composed of an outer bark or epidermis^, and: an interior, consisting of an irritable elastic cellular tissue, through which the sap necessary for its support rises from the root towards the upper part, namely the leaves and flowers. Each cell forms a small closed vesicle, a com- plete laboratory in itself, through whose membranes the sap oozes by the process of osmosis ; they stand side by side filled with most different matters,, which never become intermixed. Each of these cells extracts from the con- stantly passing current of saj:) those constituents required for its own product,, and when its allotted elaboration is completed, they are either passed on agoin in a fluid state, or reserved for the future needs of some other part of the plant, or they are used to repair or increase its own solidity. Plants are thus possessed of a vital principle, only differing in form and intensity from that oi animals. -251. The water-plant Chara, through which the sap may be seen circulating- in a current of green globules, rising through one set of transparent cells and descending through another, is usually advanced as a proof of this, and the' evidence is rendered more convincing if a ligature be tied round the centre : the motion continues as before, but is confined to each end,âtwo endless chains in place of one.
