“All the effects witnessed in the experiments of public lecturers upon mesmerism, were produced by Regazzoni in perfection, and without one spoken word to indicate what the subject was to do. He even by his silent will produced the most surprising effects upon the physical systems of persons totally unknown to him.
Directions whispered by the committee in Regazzoni’s ear were immediately obeyed by the subjects, whose ears were stuffed with cotton, and whose eyes were bandaged. Nay, in some cases it was not even necessary for them to express to the magnetizer what they desired, for their own mental requests were complied with with perfect fidelity.
Experiments of a similar character were made by Regazzoni in England, at a distance of three hundred paces from the subject brought to him. The jettatura, or evil eye, is nothing but the direction of this invisible fluid, charged with malicious will and hatred, from one person to another, and sent out with the intention of harming him. It may equally be employed for a good or evil purpose. In the former case it is magic; in the latter, sorcery.”
