THE following from the New York Herald is another one of the many illustrations of the evils that may result from hypnotism:— “RICHMOND, Va., Wednesday,—John Sweeney, who is well known in this city, was temporarily transformed into a maniac last night by the effects of hypnotism. A social party was given by Mrs. W. J. Tilman, and among the guests were Sweeney and Calvin Cooke, the latter an amateur hypnotist. “Cooke offered to give an exhibition of his skill, and Sweeney consented to be the subject. No sooner was the latter under the spell than he imagined himself a pugilist, and at once began to make a general attack upon all present, without regard to sex. “He soon cleared the house, and then began to demolish the front fence, using for the purpose a heavy ornamental urn. Sixteen men approached the young man, but he threw them right and left, and began tearing off his clothes. “A hurry call was then turned in for the police patrol wagon. It came with five policemen. The struggle resulted in the young man being handcuffed and his feet tied together. His captors held him on the ground while a physician administered a hypodermic injection of morphine. He was then hurried to a hospital and unbound. He then wrenched an iron bedstead apart. “More drugs were administered, and finally he was quieted. To-day he has returned to his normal state, but weak and nervous. Sweeney has never been regarded as remarkable for physical strength.” Hypnotism is something that any knave can learn the art of as well as the most highly educated physician. And, in view of the evils that are constantly growing out of it, how can any one say that there is any chance for it to do real good? The physicians of the country, instead of trying to create the sentiment that there is any good in hypnotism, should arise as one man and show the evil of it, and warn every one against it.
