In the two photographs
(figs. 2 and 3, on Plate V.) Mr. Rejlander has simulated this
expression with some success. With respect to the face,
moderate disgust is exhibited in various ways; by the mouth being
widely opened, as if to let an offensive morsel drop out; by spitting;
by blowing out of the protruded lips; or by a sound as of clearing
the throat. Such guttural sounds are written _ach_ or _ugh_;
and their utterance is sometimes accompanied by a shudder,
the arms being pressed close to the sides and the shoulders
raised in the same manner as when horror is experienced.[7]
Extreme disgust is expressed by movements round the month
identical with those preparatory to the act of vomiting.
The mouth is opened widely, with the upper lip strongly retracted,
which wrinkles the sides of the nose, and with the lower lip
protruded and everted as much as possible. This latter movement
requires the contraction of the muscles which draw downwards
the corners of the mouth.[8]
[7] See, to this effect, Mr. Hensleigh Wedgwood's Introduction
to the `Dictionary of English Etymology,' 2nd edit.
1872, p. xxxvii.
It is remarkable how readily and instantly retching or actual vomiting
is induced in some persons by the mere idea of having partaken
of any unusual food, as of an animal which is not commonly eaten;
although there is nothing in such food to cause the stomach to reject it.
