    place at will, exclusively belongs to animals; whilst vegetables are fixed to the soil, germinate, grow, and die in the same spot: it is erroneously supposed by some, that certain bulbous plants have this facul- ty in common with animals. When they are ob- served for several years, it is evident that they have changed place; but let us reflect that it is no longer the same plant, it is a new bulb which grows alongside of the parent, which dies every year with the plant that it produces. From these two faculties, proper to animals, arises a third, which is equally peculiar to them—lan- guage. 5. Generation. In animals, reproduction oc- curs by the voluntary union of two individuals of different sexes, whilst the greater number of vege- tables are hermaphrodites, i. e. the* same flow- er bears the two sexes; fecundation is mechanical, and is involuntarily performed. But there exists ano- ther mode of reproduction, which has the great- est analogy in the two species of organized beings; it is simple, and happens without the concurrence of two sexes. The Conferva?, the Polypi for example, cover themselves with gems or buds, in the same manner as many plants do, and which, in dropping off, give birth to new beings similar to the parents which have produced them. In the comparative examination that we have just made between animals and vegetables, we must have remarked that these beings differ only in the degree of complication or of simplicity, and if we reflect that in order to establish differences, we have been obliged to compare the most elevated among them, it will be easy to foresee, that in de- scending the animal scale, nature will present a
