STORY OF THE DIPLOMATIST {56a}
For example, there is a living diplomatist who knows men and cities, and has, moreover, a fine sense of humour.  “My Lord,” said a famous Russian statesman to him, “you have all the qualities of a diplomatist, but you cannot control your smile.”  This gentleman, walking alone in a certain cloister at Cambridge, met a casual acquaintance, a well-known London clergyman, and was just about shaking hands with him, when the clergyman vanished.  Nothing in particular happened to either of them; the clergyman was not in the seer’s mind at the moment.
