It will be noticed that Fig. 21 gives theadult as eight heads high.

Fig. 21 is divided into eighths by transverselines, the middle being marked by a heavier line. It will be noticedthat the centre of the vertical diameter falls in the adult upon the pubis,rather higher in man than in woman; in the newborn it is rather abovethe navel, and at intermediate ages at various intermediate points,gradually approximating the adult position.
