The Fourth Subject, (plate LXXIV.) is a Head of
Old Age.
This is a Woman s Head; hut the same principles
of variation apply to both Sexes.
The first thing remarkable in this head is, the dif-
ference produced by the loss of teeth : now in old
age, not only are the teeth lost, but also the gums,
and afaeoli, wherein their roots were inserted : by
this cause the inferior jaw is diminished in height;
and the mouth becomes so shallow, that often it can
hardly contain the tongue. As the tongue, by this
shallowness of the jaw, is pressed, with the os kvoides,
toward the roof of the mouth, it is not held so closely
as before with its root, but is apt to fall forward
whenever aged persons incline their heads. By this
aptitude the tongue appears longer than formerly.
The nose, whose prop, the jaw, is now impaired
by loss of teeth, inclines toward the mouth, over
which it almost seems to hang.
The forehead, above the nose, projects more than
heretofore, because the frontal sinus is larger : hence
also, the hollow at the junction of the nose and fore-
head, becomes more apparent.
The whole upper-jaw becomes hollower ;x and the
front which formerly projected now recedes; where-
by the whole upper-lip seems fallen into the mouth ;
and the nose seems larger, not only than it was, but
also than it really is.
The lower jaw is now, by the loss of its teeth, so
much in the power of its muscles, which no longer
find the resistance they formerly did, that it is drawn
up
