" It was very kind in you to pat Flush’s head in defiance of danger and from pure regard for me. I kissed his head where you had patted it; which association of approximations I consider as an imitation of shaking hands with you and as the next best thing to it. You understand — don’t you? — that Flush is my constant companion, my friend, my amusement, lying with his head on one page of my folios while I read the other. (Not your folios — I respect your books, be sure.) Oh, I dare say, if the truth were known, Flush understands Greek excellently well. "
