Within recent years there have been further attempts in the States to make capital out of the popular respect for, and ignorance of, electronic apparatus. The first of these was exposed by a Federal inquiry, and revealing details were published in radio journals. The outfit had certainly developed since Abrams’ day, being similar to the more impressive type of super-radiogram in appearance, and filled with a bewildering conglomeration of radio components. The function of these, however, was exactly as in Abrams’ effort—psychologically potent but electrically nil. The gadget’s alleged function changes little with the years: it "determines the wavelength of the disease vibrations" and then, by throwing a switch "generates vibrations which will cancel those of the disease". The diagnosis can be made from the patient in person, from a drop of his blood, or even from his handwriting. Astonishing—if only it were true. But, still, the personal factor - in the form of the operator (physician)—is involved, and any success the machine may have is due solely to the ability of the practitioner to diagnose from superficial symptoms, and on the psychological effect of the apparatus, and the sales talk, on the patient.

At least one operator has imaginatively extended his scope by using the gadget only for diagnosis. For therapeutic effects he relies on his own special collection of homeopathic and biochemic remedies.

The attraction of the mystic power of electricity is exploited in many other ways. Connecting a group of people "in circuit" by means of copper wires is practised for the alleged purpose of "causing a healing current to flow"—or words to similar effect. When the sceptic demonstrates that no electric current of significant nature or magnitude does flow, the operator is liable to take refuge in double-talk about "vibrations of etheric rather than purely electrical character". This may satisfy the anxious-to-believe patient, but cuts little ice with the healthy student of electronics. Perhaps to avoid such criticism, the wires are sometimes omitted, and the group holds hands to form a ring. There is no doubt that intense emotional and nervous reactions can be generated by such a group: but that the reactions are wholesome and healthful is at least questionable. Just as in mobs of greater number, it is likely that the least balanced intelligence and the feelings of the emotionally immature will tend to predominate.

The stopping of disease symptoms by excitement is practised in many forms. it is essentially self-deceit and, like the now outmoded Coue system, is liable to aggravate the physical distress of the body by upsetting its nervous co-ordination and control.
