feeling, in insects. I say the feeling, not the touch; for the touch seems, as it were, a supervention to the feeling, a perfection given to it by the reaction of the higher powers. As the feeling of the insect, in subtlety and virtual distance, rises above the solitary sense of taste[1] in the mollusca, so does the smell of the fish rise above the feeling of the insect. In the fish, likewise, the eyes are single and moveable, while it is remarkable that the only insect that possesses this latter privilege, is an inhabitant of the waters. Finally, here first, unequivocally, and on a large scale, (for I pretend not to control the freedom, in which the necessity of Nature is rooted, by the precise limits of a system,)—here first, Nature exhibits, in the power of sensibility, the consummation of those vital forms (the nisus formativi) the adequate and the sole measure of which is to be sought for in their several organic products. But as if a weakness of exhaustion had attended this advance in the same moment it was made, Nature seems necessitated to fall back, and re-exert herself on the lower ground which she had before occupied, that of the vital magnetism, or the power of reproduction. The intensity of this latter power in the fishes, is shown both in their voracity and in the number of their eggs, which we are obliged to calculate by weight, not by tale. There is an equal intensity both of the immanent and the projective reproduction, in which, if we take in the comparative number of individuals in each species, and likewise
- ↑ The remark on the feeling of the antennæ, compared with the touch of man, or even of the half-reasoning elephant, is yet more applicable to the taste, which in these gelatinous animals might, perhaps not inappropriately, be entitled the gastric sense.
