6, been thus acted on to a slight extent, its curvature would
have been less rigid, the naso-labial farrow would have been
slightly different, and the whole expression would, as I believe,
have been more natural, independently of the more conspicuous
effect from the stronger contraction of the lower eyelids.
The corruptor muscle, moreover, in fig. 6, is too much contracted,
causing a frown; and this muscle never acts under the influence
of joy except during strongly pronounced or violent laughter.

B. i. s. 144. See my woodcut (H. fig. 2).
By the drawing backwards and upwards of the corners of the mouth,
through the contraction of the great zygomatic muscles,
and by the raising of the upper lip, the cheeks are drawn upwards.
Wrinkles are thus formed under the eyes, and, with old people, at their
outer ends; and these are highly characteristic of laughter or smiling.
As a gentle smile increases into a strong one, or into a laugh,
every one may feel and see, if he will attend to his own sensations
and look at himself in a mirror, that as the upper lip is drawn up
and the lower orbiculars contract, the wrinkles in the lower eyelids
and those beneath the eyes are much strengthened or increased.
