Some will ask the question, "If these things be true, why have we not heard of them before?" We confess that we know of no other possible reason than that such inquiries are not "_posted up_," as they should be, in matters of history and science. But, before closing this part of our subject, we propose to relate a few more incidents, by way of illustration. "In the year 1849-50, certain highly-respectable houses in the city of New York seem to have been all at once unaccountably beset with a strange power, which seized upon particular parts, and would not allow any one, not even the members of the families, to touch those seemingly consecrated things. Whenever this was attempted, a loud, sharp sound would be instantly given, accompanied with a sharp and spiteful flash of light, as if the agent was determined to protect that which it had seized upon. But this was not all; it would smartly shock the intruder with a blow, as if with an unseen fist, or the like. It even seized upon the members of these families at times, and would--so to speak--make them apparently strike one another, in an unseen manner, simultaneously. It was often the case that a stranger could not call at the door without being instantly struck on the wrist or elbow, on touching the knob of the door bell; and he would see, at the same instant, an angry flash of light, as if from some demon's eye. The ladies were not allowed to kiss each other without each receiving, on the approach of their lips, a fiery smack, as from a spirit's lips. The dear little ones of these families were prevented from giving their mothers the parting salutation on retiring for the night." "There _seemed_ to be a great deal of cunning shown by this agency. If the lady of the house did not think to pay all due deference to its rules, when she wished to give orders to the servants below through the metallic speaking tube, she was sure to receive an unseen blow in the mouth, almost sufficient to stagger her: at the same instant she would see the flash of what might have been taken for a 'fiery,' if not for an 'evil eye.'"
