The device is revealed when the subject of the book--the well-traveled spirit medium William Eglinton--was invited in May of 1878 to travel to Cape Town, South Africa, for seance sittings with the Cape Town Psychological Society. His host and sponsor was one Dr. Berks T. Hutchinson, with whom he would stay 9 months as the subject of psychical study when the preliminary sittings with the Psychological Society soured with dissent, and with whom he would also study dentistry during his months abroad, to the extent that he was a "duly-qualified practioner" on his return to England the following year.
Eglinton made the trip in July of 1878 and arrived in August, apparently after enduring contention while trapped aboard his steamer with a dissatisfied former client who saw fit to prejudice the other travelers against the medium's claimed abilities. On his arrival in Cape Town, the author of the book--here most likely T. L. Nichols--relies heavily on Dr. Hutchinson's own notes taken during the nine-month span to build the narrative of Eglinton's time abroad.
Dr. Hutchinson had first become acquainted with Eglinton's mediumship in 1877 while on a trip to England, and while he did not have a chance for a sitting then, was impressed enough with what he heard of the medium's abilities to sponsor his visit to South Africa, where he was a houseguest of the dentist and even inducted into Hutchinson's Cape Town Masonic Lodge.

"A disk made of galvanised sheet iron, eighteen inches in diameter, had white paper pasted over the upper part, and around the edge were arranged the letters of the alphabet, together with the words " Yes " and " No." (Fig. 4). In the centre a small round hole, about half an inch in diameter, was cut, and a pin about three inches long by one-eighth of an inch thick put through; on the top of this was a wooden pointer, arrow-shaped, fixed on so that by having a small crosspiece of wood fixed to the under part, a materialised spirit hand could move the arrow round to any letter. In the centre of my seance table I had cut out a small circular piece (which I leave in when not wanted), so that spirits might project their hands ; the space immediately beneath the wood of the table made a sort of camera, which prevented the light falling on the spirit hands, and thereby dissipating the material molecules collected over them. Having taken out the circular piece of wood, I placed the circular disk over the hole, and then fixed the cross-piece to the portion of the pin that was beneath the table. The apparatus looks very much like a telegraphic instrument I have seen, where the operator moves the key round to the different letters."
According to Hutchinson's account of Eglinton's sittings with his dial plate, the initial communications and the method of their attainment were quite remarkable: the isolated dial plate, surrounded by 9 sitters and the medium, produced a full-light message as Eglinton entered a trance. Hutchinson attested that the "arrow of the dial began to oscillate and revolve alternately" and "spin round at a very rapid rate, then stop, and oscillate, and vibrate strongly; the sensitive shivered, and was much agitated whilst the arrow was in motion" in conditions in which "no blind force could act on the apparatus." In other words, by Hutchinson's account, the dial plate produced rapid messages surrounded on all sides by 9 sitters, physically unmanipulated by the medium. This phenomenon produced only a two messages in this fashion, however--"Godunderstandsiloveyoualljoeyiswithyou" and "Isolatethemedium"--before Eglinton lapsed from his trance and "suggested that his eyes should be blindfolded and his hand be allowed to guide the arrow" in a more traditional and believable display of device manipulation.
Hutchinson, at least, was convinced: "Where there was no confederate, scientific mechanism, or a properly arranged platform or apparatus with secret machinery, nothing would make the simple apparatus act as I have stated, except guided by supernatural means." It may be that the device was manipulated from beneath as the design intended, though whether it was the work of manifest spirit hands or Eglinton's own efforts I leave my scrupulous readers to decide. Other sittings with the device followed, but none matched the initial hands-free phenomenon:
"At one improvised sitting, we received several messages by the aid of the dial, the hand of the medium directing it. To get messages by direct agency is too trying for the sensitive; hence, when his hand is used, it greatly economises power."
