 First, that in the lower grade the reproductions themselves seem merged in those of irritability, from the very circumstance that the latter constitutes no pole, either to the former, or to sensibility. The force of irritability acts, therefore, in the insect world, in full predominance; while the emergence of sensibility in the fish calls forth the opposite pole of reproduction, as a distinct power, and causes therefore the irritability to flow, in part, into the power of reproduction. The second result of this ascent is the direction of the organizing power, ad intra, with the consequent greater simplicity of the exterior form, and the substitution of condensed and flexible force, with comparative unity of implements, for that variety of tools, almost as numerous as the several objects to which they are to be applied, which arises from, and characterises, the superficial life of the insect creation. This grade of ascension, however, like the former, is accompanied by an apparent retrograde movement. For from this very accession of vital intensity we must account for the absence in the fishes of all the formative, or rather (if our language will permit it) fabricative instincts. How could it be otherwise? These instincts are the surplus and projection of the organizing power in the direction ad extra, and could not, therefore, have been expected in the class of animals that represent the first intuitive effort of organization, and are themselves the product of its first movement in the direction ad intra. But Nature never loses what she has once learnt, though in the acquirement of each new power she intermits, or performs less energetically, the act immediately preceding. She often drops a faculty, but never fails to pick it up again. She may seem forgetful and
