mysterious as this matter is, many of the phenomena are settled 'facts' which plainly contradict the vague 'opinions' set afloat by those who know little of what they talk or write about. Take, for instance, a note--published in _The Evening Post_--by a person who was present at the interview for the investigation of the subject, at the rooms of Dr. Griswold, in which he says that 'all the persons present on that occasion (whom he has since seen) are of the opinion that the phenomena, or knockings, were electrical, and the answers accidental.' These may not be his precise words, yet they embody correctly his expression; but they are incorrect in fact, and in their implication; as all of the persons then present have not been consulted, far less have they given an unanimous opinion as above expressed. "Before any one adopts the 'opinion' that these sounds are electrical, would it not be well to show how they can be produced while the three persons on whom they are attendant are insulated several feet apart; how electricity can be so harnessed to tables, chairs, and other things, as to move them about, or hold them in their places so that no human arm can stir them, or produce a concussion equal to what would require the force of a strong arm to accomplish and with the aid of a heavy instrument; without saying anything of the still more wonderful manifestations indicating intellectual direction. Any one who can give the rationale of all this, upon electrical principles, will undo some of the established and known laws, and discover to the world not only the means for converting this subtle agent into _an intelligent_ motive power, but also to give it the skill of a masterly engineer. "The assumption that the correct answers given to questions that evening--though not remarkable, comparatively--were 'accidental,' bears absurdity upon the face of it. Such 'opinions' throw no light upon the mystery, but leave it still more inexplicable to the general intelligent mind.
