from The Century Dictionary and Cyclopedia
- n. An apparatus for viewing distant objects in spite of intervening obstructions. It consists of an aërial camera obscura, so attached to a kite-sustained cable that an image of distant objects is thrown on a horizontal ground-glass plate or on thin paraffined paper acting as the screen of the camera. The observer on the ground views the image by the aid of a field-glass. It was invented by W. A. Eddy.
