An instrument for mechanical communication with spirits,
invented by George Jobson and B. K. Kirkby. It consisted of a
large typewriter, the key-contacts of which were so sensitive
that by merely blowing upon them they could be depressed,
closing an electric circuit and making an illuminated letter appear.
The machine, however, was by no means independent of
human action. The presence of the medium L. E. Singleton was
necessary. When she was entranced, a hand (suggestive of
fraud) appeared out of the cabinet, tapped the keys, and
spelled out messages which were then flashed in luminous letters
on a six-foot indicator. (See also Ashkir-Jobson Trianion;
