It was evident that the remembrance of some very strange and out-of-the-way joke must occasionally flit across him, and then he gave his hyena-like laugh, but it was so short, so sudden, striking upon the ear for a moment, and then gone, that people have been known to look up to the ceiling, and on the floor, and all round them, to know from whence it had come, scarcely supposing it possible that it proceeded from mortal lips."
