One thing about this face was very strange and startling. You could not look upon it in its most cheerful mood without feeling that it had some extraordinary capacity of expressing terror. It was not on the surface. It was in no one feature that it lingered. You could not take the eyes or mouth, or lines upon the cheek, and say, if this or that were otherwise, it would not be so. Yet there it always lurked-something for ever dimly seen, but ever there, and never absent for a moment.
