And again, when he had made a previous arrangement with his family that they should do certain things every quarter of an hour at home—he, of course, not knowing what—while he was to ask the ‘spirit’ what was done at the instant, uniform failure occurred. He proved, too, that the theory of the ‘spiritualists’ to meet such difficulties—viz., that evil or trifling spirits interfered at _their_ end of the telegraph—was not tenable.
