Jerry was sitting down for breakfast one morning when he was astonished to see in the paper an announcment of his own death.
He called his friend at once, "Jim, have you seen the announcement of my death in the paper?"
Jim replied, "Yes, and exactly where are you calling from?"
Hearing aidIn 1880, the first U.S. patent for an electric hearing aid was issued to Francis D. Clarke and M.G. Foster, titled a Device for Aiding the Deaf to Hear (No. 226,902). The device employed bone conduction by which sound is passed through vibration of the skull bone. It was not until 1901 that the first commercially available hearing aid was produced, the Acousticon, invented by Miller Reese Hutchinson.. |
