It has been long known to contain some small branched corpuscles, almost indis- tinguishable from young nerve cells; and of late the much branched processes of many fully developed nerve cells have also been thought to have a structural continuity with this minute net- work of the neuroglia. If these . .

This intermediate tissue is, in short, the probable matrix wherein and from which new nerve fibres and new nerve cells are evolved in animals, of whatsoever kind or degree of organization, during their advance in reflex, in instinctive, or in intellectual acquirements. Some such process must take place, pari passu with the acquisition of new know- ledge and powers, of all kinds and howsoever acquired: whether it comes, as in lower animals, from mere intercourse with natural phenomena; or, as amongst ourselves, from similar means, supplemented by individual application in the mastery of educational or professional pursuits and of all kinds of handiwork; or whether the new knowledge and powers come to us as a result of that more general edu- cation or * experience ’ which is gained by daily intercourse with the pleasures, troubles, turmoils, and exertions in- separable from social life.
