At the last visit Professor Hyslop paid to his father, in January or February 1895, a long conversation took place between them on religious and philosophical subjects. Professor Hyslop spoke of his psychical studies. The possibility of communication between the two worlds was discussed at length, and Swedenborg and his works were mentioned. During the sittings Robert Hyslop constantly returns to this conversation, which had made a profound impression on him; much more profound than would have been expected, considering his religious views. He recalls the points which were discussed by him and his son one after another, and adds, "You remember I promised to come back to you after I had left the body, and I have been trying to find an opportunity ever since." Now, no such promise had been made explicitly. But James Hyslop had written to his father on his deathbed, "Father, when all is over, you will try to come back to me." Robert Hyslop must from that moment have resolved to return if possible; and he must have believed he had told his son so, which was not the case. When he was living in Ohio, Mr Robert Hyslop had a neighbour named Samuel Cooper. One day Cooper's dogs killed some sheep belonging to Robert Hyslop. An estrangement followed, which lasted several years. At one of the sittings in which Dr Hodgson represented Professor Hyslop, he asked a question which the latter had sent him in writing. Professor Hyslop hoped the question would turn his father's attention to the incidents of his life in Ohio. The question was, "Do you remember Samuel Cooper, and can you say anything about him?" The communicator replied, "James refers to the old friend I had in the West. I remember the visits we used to make to each other well, and the long talks we had concerning philosophical topics." At another sitting, when Dr Hodgson was again alone, he returned to the same idea. "I had a friend named Cooper who was of a philosophical turn of mind and for whom I had great respect, with whom I had some friendly discussion and correspondence. I had some of his letters ... you will find them." Another time, when Professor Hyslop was present, he said, "I am trying to remember Cooper's school." The next day he returns to the point, "You asked me, James, what I knew about Cooper. Did you think I was no longer friend of his? I had kept some of his letters; and I think they were with you." In all this there was not a trace of Samuel Cooper, and Professor Hyslop did not know what to think. He therefore put a direct question in order to bring his father back to the point he had in mind. "I wanted to know if you remembered anything about the dogs killing sheep?" "Oh, I should think I did ... but I had forgotten all about it. That was what we had the discussion about.... Yes, very well, James, but just what you asked me this for I could not quite make out as he was no relation of mine ... if I could have recalled what you were getting at I would have tried to tell you.
