For this reason they do not constrain their face, but let it out freely. It is otherwise with those who from childhood have learned to dissemble. Their face is thus contracted interiorly, lest something of their thought should shine forth. Neither is it let forth outwardly, but is held ready to let itself out or contract itself, according as cunning suggests.

For there are manifold series of fibers there, folded together and intertwined, which were created not only for masticating and for speech by words, but also for expressing the ideas of the mind.
