Note 37 — SPECIALIZED ADMINISTRATION.

Here, and throughout the discussion, I refer to these controlling systems only as they exist in the Vertebrata, because their relations are far better known in this great division of the animal kingdom—not because like relations do not exist elsewhere. Indeed, in the great sub-kingdom Annulosa, these controlling systems have relations that are extremely significant to us here. For while an inferior annulose animal has only a single set of nervous structures, a superior annulose animal (as a moth) has a set of nervous structures presiding over the viscera, as well as a more conspicuous set presiding over the organs of external relation. And this contrast is analogous to one of the contrasts between undeveloped and developed societies; for, while among the uncivilized and incipiently civilized there is but a single set of directive agencies, there are among the fully civilized, as we shall presently see, two sets of directive agencies, for the outer and inner structures respectively.
