[ ‘Anatomy of
Expression,’ pp. 137, 139. It is not surprising that the corrugators
should have become much more developed in man than in the anthropoid apes;
for they are brought into incessant action by him under various
circumstances, and will have been strengthened and modified by the
inherited effects of use. We have seen how important a part they play,
together with the orbiculares, in protecting the eyes from being too much
gorged with blood during violent expiratory movements. When the eyes are
closed as quickly and as forcibly as possible, to save them from being
injured by a blow, the corrugators contract. With savages or other men
whose heads are uncovered, the eyebrows are continually lowered and
contracted to serve as a shade against a too strong light; and this is
effected partly by the corrugators. This movement would have been more
especially serviceable to man, as soon as his early progenitors held their
heads erect. Lastly, Prof. Donders believes (‘Archives of Medicine,’ ed.
by L. Beale, 1870, vol. v. p. 34), that the corrugators are brought into
action in causing the eyeball to advance in accommodation for proximity in
vision.]

acquire permanently expanded nostrils, owing to the habitual contraction
of the elevatory muscles of the wings of the nose. The explanation by Dr.
Piderit (‘Mimik und Physiognomik,’ s. 82) of the distension of the
nostrils, namely, to allow free breathing whilst the mouth is closed and
the teeth clenched, does not appear to be nearly so correct as that by Sir
C. Bell, who attributes it to the sympathy (i. e. habitual
co-action) of all the respiratory muscles. The nostrils of an angry man
may be seen to become dilated, although his mouth is open.]

If, instead of using the vague term symboliquement, Gratiolet had
said that the action was a remnant of a habit acquired during primeval
times when our semi-human progenitors fought together with their teeth,
like gorillas and orangs at the present day, he would have been more
intelligible. Dr. Piderit (‘Mimik,’ &c., s. 82) also speaks of the

air by a succession of rapid short sniffs. If “the nostrils be watched
during this process, it will be seen that, so far from dilating, they
actually contract at each sniff. The contraction does not include the
whole anterior opening, but only the posterior portion.” He then explains
the cause of this movement. When, on the other hand, we wish to exclude
any odour, the contraction, I presume, affects only the anterior part of
the nostrils.]
