As the doctors struggled to understand the extent of Garfield's wounds, Alexander Graham Bell, inventor of the telephone, used this machine that he called an "induction balance" to try to locate the bullet. Wen found, the machine was to send a sound to the attached telephone receiver. Despite attempts on July 26 and August 1, 1881, Bell could not situate the bullet.
