Four years previously, a poor immigrant, a Catholic Irishwoman, had been hanged in Boston for bewitching four children, named Goodwin--one of whom, a girl of thirteen, had sorely tried a reverend man, less irascible than Mr. Parris, but nearly as excitable. The tricks that the little girl played the Reverend Cotton Mather, when he endeavored to exorcise the evil spirits, are precisely such as are familiar to us, in cases which are common in the practice of every physician. If we can not pretend to explain them--in the true sense of explaining--that is, referring them to an ascertained law of nature, we know what to look for under certain conditions, and are aware that it is the brain and nervous system that is implicated in these phenomena, and not the Prince of Darkness and his train. Cotton Mather had no alternative at his disposal. Satan or nothing was his only choice. He published the story, with all its absurd details; and it was read in almost every house in the Province. At Salem it wrought with fatal effect, because there was a pastor close by well qualified to make the utmost mischief out of it. [In cases of _hysteria_, the phenomena are sometimes so remarkable, that one is disposed to attribute their cause to influences beyond nature.] PARRIS AND HIS "CIRCLE." Mr. Parris had lived in the West Indies for some years, and had brought several slaves with him to Salem. One of these, an Indian named John, and Tituba his wife, seem to have been full of the gross superstitions of their people, and of the frame and temperament best adapted for the practices of demonology. In such a state of affairs the pastor actually formed, or allowed to be formed, a society of young girls between the ages of eight and eighteen to meet in his parsonage, strongly resembling those "circles" in the America of our time which have filled the lunatic asylums with thousands of victims of "spiritualist" visitations. It seems that these young persons were laboring under strong nervous excitement, which was encouraged rather than repressed by the means employed by their spiritual director. Instead of treating them as the subjects of morbid delusion, Mr. Parris regarded them as the victims of external diabolical influence; and this influence was, strangely enough, supposed to be exercised, on the evidence of the children themselves, by some of the most pious and respectable members of the community.
