However, the later experiments by the same observers, recorded below, in which a marked degree of success was obtained with agent and percipient in different rooms, will no doubt be considered to render untenable any explanation of the kind above indicated. This further series was carried on through the years 1890-1-2. Mrs. Sidgwick, aided by Miss Johnson, conducted the experiments throughout, with the occasional assistance of Professor Sidgwick, Dr. A. T. Myers, and others. The percipients were P., T., Miss B., and three others, and Mr. G. A. Smith was in nearly all cases the agent. Some of these experiments, as in the last series, were with numbers of two digits; but the percipient was now in a different room from the agent. At first the trials were carried on in an arch, fitted up with two floors, under the Parade at Brighton. On the ground-floor was a little lobby, kitchen, etc.; on the upper floor a sitting-room about 15 feet square. The staircase, which, as shown in the plan subjoined, led directly out of the upper room, was not enclosed above, but had a door below, which was kept shut during the experiments. The floor of the room above was covered with a thick Axminster carpet. Even so the sound-insulation was not perfect; but it was found that words spoken in ordinary conversation on one floor were indistinguishable on the other unless the ear was pressed against the door or wall of the staircase. In the experiments carried on at Mrs. Sidgwick's lodgings in Brighton the percipient sat in the room at a distance from the door, which was closed, varying from 9 to 13 feet, and Mr. Smith was in the passage outside, Miss Johnson sitting between him and the door. Of course strict silence was observed by the agent. One of the experimenters, in most cases Miss Johnson, accompanied the agent, drew the number from the bag, and noted each as it was drawn. Mrs. Sidgwick, of course in ignorance of the number drawn, sat by the percipient and took notes of his remarks. As in the previous series, the impressions received by the percipient, who in the first experiments was Miss B., appear generally to have been of a visual nature. Details of all the trials with Miss B. as percipient and Mr. Smith as sole agent are given in the following table:-- No. 14.--By MRS. SIDGWICK AND OTHERS. (1) PLACE, THE ARCH.
