July 15th 1956
Dear Josh and Esther,
You'd shipped away before I'd realized it.  This is just a brief line to thank you for the very enjoyable weekend, not forgetting the trip over the lake.  I do hope you fit in the visit to Europe.  When you come to Cambridge you must stay with us--just drop a postcard.  Odile is very curious to know what you look like.
Remember me to Woods Hole--[ . . . ]
Yours ever,
Francis
