September 29 , 19I4I Mr. George Detweiler, 3pi3 Lewis Tower building, , Fifteenth and Locusts Streets, Philadelphia, Pennsylvania. Bea r Mr. Betweiier; ' Pursuant to our telephone conversation of this morning, I am sending you under separate cover a book into which are bound a series of articles from this Laboratory, which I think will be of interest to y ou in connection with your case. I put slips of paper in the book to mark certain articles which .*111 bo of p a rticular interest. I am sending several more recent articles which may also be of interest to you. All of the articles contain refe rences to the work of other experimentalists in this field. Let me warn you at this time that the book waich I a m sen ding you must not be made an exhibit, and so a part of the record in this case. In fact, these books are now out of print, and I c a n only lend you this one for your immediate use. I would appreciate It if you w ould lit me k n o w as e a r l y as possible the approximate date o n v?hich I shall have to a p pear in connection with this case, since my engagements are fairly numerous at this season of the year. Incidentally, I expect to be in Atlantic City on the week of October 13, at a scientific meeting. If it would serve any useful pur pose, I could call on you some time during that week and discuss such phases of the case as you m a y wi sh to bring up. Very truly yours, RAK ef Robert A. diehoe, M, d .
