Two Autograph Letters Signed, to President Garfield's private secretary J. Stanley Brown.
July 15: "Experiments made last night with Induction Balance very promising. Please send two bullets same size as that in President's body. Keep newspaper correspondents away from my laboratory if possible."
After the assassination attempt on President Garfield on July 2, Bell offered to help extract the bullet that was lodged in the President's back by means of an electro-magnetic device. By the time the device was ready for use, the President's physicians refused to allow it to be employed because of their patient's weakness.
