With your extraordinary zeal in good deeds you have written to me to say that you yourself owe me double thanks; first, for getting a letter from me, and secondly, for doing me a service.  What thanks, then, must not I owe you, both for reading your most delightful words, and for finding what I hoped for so quickly accomplished!  The message was exceedingly gratifying on its own account, but it gave me much greater gratification from the fact that you were the friend to whom I owed the boon.  God grant that ere long I may see you, and return you thanks in words, and enjoy the great pleasure of your society.
