ATTENTION., if sudden and close, graduates into sur-
prise; and this into astonishment; and this into stupe-

they are raised to a much greater extent, with the eyes
and mouth widely open. The raising of the eyebrows
is necessary in order that the eyes should be opened
quickly and widely; and this movement produces trans-
verse wrinkles across the forehead. The degree to which
the eyes and mouth are opened corresponds with the de-
gree of surprise felt; but these movements must be co-
ordinated; for a widely opened mouth with eyebrows
only slightly raised results in a meaningless grimace, as
