Why not over a much larger surface? The matters which enter into the constitution of the appendage exist in the blood, consequently are not confined to any locality. The reason is evident, according to the physiological princi- ples laid down. Particular parts of the cutaneous surface represent different degrees of vital action in subjacent tissues; and hence organic necessities, for the expulsion of useless elements, uriU vary with these circumstances. Hair appears on the entire surface of the... body, but, ex- cept in certain regions, it is short, fine, and small in quan- tity. The presence of it to this extent is an important fact bearing directly on these views. Why does it occur in this limited form? It shews that cutaneous transpiration does not remove from the skin the whole of the materials arising from the actions of which it is the seat. Unexcited as these are, it is clear that there are elements disengaged which can find an issue only in the growth of hair. In extending this line of argument, we perceive, in passing from the general surface of the body, to a particular region, in which vital operations are characterised by greater ac- tivity, that hair is proportionately developed.
