The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Expression of Emotion in Man and Animals by Charles Darwin: expression "with singular precision," told Dr. Crichton Browne
that all her family had possessed the power in a remarkable degree.
The same hereditary tendency is said to have extended, as I likewise
hear from Dr. Browne, to the last descendant of the family,
which gave rise to Sir Walter Scott's novel of `Red Gauntlet;'
but the hero is described as contracting his forehead into a
horseshoe mark from any strong emotion. I have also seen a young
woman whose forehead seemed almost habitually thus contracted,
independently of any emotion being at the time felt.
The grief-muscles are not very frequently brought into play;
and as the action is often momentary, it easily escapes observation.
