He found that the
projection of the pelvic floor varied from nothing to as much as
two inches, and that in healthy women who had borne no children
the distance between the coccyx and anus, the length of the
perineum, the distance between the fourchette and the symphysis
pubis, and the length of the vagina are subject to wide
variations. (_Lancet_, October 12, 1889.) Even the female
urethral opening varies very greatly, as has been shown by Bergh,
who investigated it in nearly 700 women and reproduces the
various shapes found; while most usually (in about a third of the
cases observed), a longitudinal slit, it may be cross-shaped,
star-shaped, crescentic, etc.; and while sometimes very small, in
about 6 per cent. of the cases it admitted the tip of the little
finger. (Bergh, _Monatsheft fuer Praktische Dermatologie_, 15
Sept., 1897.)
As regards both sexes, Stanley Hall states that "Dr. F.N.
Seerley, who has examined over 2000 normal young men as well as
many young women, tells me that in his opinion individual
variations in these parts are much greater even than those of
face and form, and that the range of adult and apparently normal
size and proportion, as well as function, and of both the age and
order of development, not only of each of the several parts
themselves, but of all their immediate annexes, and in females as
well as males, is far greater than has been recognized by any
writer.
