THE most perplexing of all the phenomena of Spiri tualism are perhaps those in which the spirits of persons still living in the body have manifested or made them selves visible at spirit circles. At one of the meetings of the Gower-street conference, this subject occupied the whole evening, and we have notes of the whole of the proceedings, so that out of the valuable information given at those meetings, a portion has been saved from the general loss. The following is the testimony given by Mrs. Emma Hardinge in her opening address at the meeting of the conference just mentioned: Mrs. Hardinge said that she would state some facts that had come under her own observation in connection with the subject of the “ double.” The Rev. S. Binning, of New York, who is now living anybody could write to him to get the facts authenti cated—was eighteen years ago, a Wesleyan Methodist; he afterwards became a Spiritualist, and joined what was then known as the “ New York Circle” (consisting of about twenty individuals), which had several branch circles connected with other towns. One of these circles met one night at Troy, 160 miles from New York. There were twenty persons present. Accord ing to their rules each member had to be in the room twenty minutes before the circle began sitting, and to stop the sitting out. One Saturday evening, when both circles, so far apart, were sitting, the Rev. S. Binning was expected in Troy. He did not come at the set time, and they began to sit at eight o’clock, when a ring was heard at the door. Two of the members rose, and answered the bell; Mr. Binning entered, much to their surprise, as they had ceased to expect his coming that time. He muttered some indistinct words, and pushed past them in tho hall passage, opened the door where the circle was sitting, and was beheld by eighteen of the members. He again spoke indistinctly, and quitted the room. The two who had been to the door then came in and asked for him—“ Had they not seen him again at the door?” “No!” They searched the passage and the house, but he could not be found. Next day, a telegram was received from him, stating that he was seriously ill, and could not attend. He had started the telegram from New York the night before, but owing to bad weather the wires had met with an acci dent, and it did not reach its destination till the follow ing morning. He stated afterwards, that at the very time he was seen his thoughts were earnestly fixed upon the circle, and he felt anxious they should get his message. In this case of the “ double ” it would be seen that three senses were appealed to—sight, touch, and hearing. Another case occurred in a family of the name of Dorchenbach at Wisconsin. The aged mother of the family had bought some land, and with somewhat of the childishness of extreme old age, was in, the habit of going very often to see it on a Sunday. One week she bought a new dress, and determined to first wear it when visiting her land next Sunday; but she was ill, and at the usual time of paying her visit was seized with a swoon, from which she recovered in about half  an-hour. Her son, who had fetched the doctor, then went back with him to the inn where he had left his horse. The landlord asked him who was ill, and the told him. He said, “That is quite impossible, for she passed through my back kitchen, and went out to see her land as usual." The landlady also declared she had seen her, and described her new dress, which had never yet been worn. A lad here came in from the land, and said he had seen Madame Dorchenbach there. She had been seen by three persons Another case occurred in Salem, Illinois. I was staying at the house of a lady friend whose last hour was approaching. She grieved at the absence of all her children ; especially of one, a little cripple, and bemoaned herself bitterly. I left her at four o’clock and called again late at night, when she was better, and said—“ I have seen my children, and dear little Jessie sitting on the grass in the midst of her sisters, playing with roses. She passed away for the better world. Some days afterwards we learned by letter that at the time when she saw her children, little Jessie, the cripple, who had been put out of doors to play, was heard to scream. Her sisters ran out, and found her covered with roses. She said she had seen her mother, and although there were rose bushes not
