He attached a double leather head-band to his head. At each end of the band was attached a round metal disc that pressed closely on the temples. From each metal disc an insulated wire led to a small square box, the Menograph, or mind-writer.

He then pressed a button and a low humming was heard; simultaneously two small bulbs began to glow with a soft green fluorescent light. Grasping a button connected with a flexible cord to the Menograph, he leaned back in his chair.

After a few minutes' reflection he pressed the button, and at once a wave line, traced in ink, appeared on a narrow white fabric band, the latter resembling a telegraph recorder tape.

The band which moved rapidly, was unrolled from one reel and rolled up on another. Whenever the inventor wished to "write" down his thoughts, he would press the button, which started the mechanism as well as the recording tracer.

Where the wave line breaks, a new word or sentence commences; the three words shown are the result of the thought which expresses itself in the words, "In olden times." ...)

The Menograph was one of Ralph 124C 41+'s earliest inventions, and entirely superseded the pen and pencil. It was only necessary to press the button when an idea was to be recorded and to release the button when one reflected and did not wish the thought-words recorded.
