The front page includes; "Escape Of Boss Tweed" "The Notorious Criminal Follows the Example of His Associate and Runs Away". Page 2 has: "New Discovery in Electricity" which begins: "T. A. Edison of Newark, N.J., an electrician and inventory, has just made a discovery...which it is expected will throw new light on the nature of electricity and possibly manifest the existence of a hitherto unknown natural force..." and further on: "...Mr. Edison has named the new principle 'etheric force'...". See the hyperlink on "etheric force" learn this was essentially the discovery of radio waves.
Four pages, large folio size, minor loss at the blank spine margin otherwise very nice.
