British face from which emotion has been so carefully banished

His face was the sort of British face from which emotion has been so carefully banished that a foreigner is apt to think the wearer of the face incapable of any sort of feeling; the kind of face which, if it has any expression at all, expresses principally the resolution to go through the world decorously, without intruding upon or annoying anyone.
