So in the written communications, I have in a previous paper pointed to the "Gate of Remembrance" case, but there is a great mass of material which proves that, in spite of mistakes and failures, there really is a channel of communication, fitful and evasive sometimes, but entirely beyond coincidence or fraud. These, then, are the usual means by which we receive psychic messages, though table tilting, ouija boards, glasses upon a smooth surface, or anything which can be moved by the vital animal-magnetic force already discussed will equally serve the purpose. Often information is conveyed orally or by writing which could not have been known to anyone concerned. Mr. Wilkinson has given details of the case where his dead son drew attention to the fact that a curio (a coin bent by a bullet) had been overlooked among his effects. Sir William Barrett has narrated how a young officer sent a message leaving a pearl tie-pin to a friend. No one knew that such a pin existed, but it was found among his things. The death of Sir Hugh Lane was given at a private seance in Dublin before the details of the Lusitania disaster had been published. On that morning we ourselves, in a small seance, got the message "It is terrible, terrible, and will greatly affect the war," at a time when we were convinced that no great loss of life could have occurred. Such examples are very numerous, and are only quoted here to show how impossible it is to invoke telepathy as the origin of such messages. There is only one explanation which covers the facts. They are what they say they are, messages from those who have passed on, from the spiritual body which was seen to rise from the deathbed, which has been so often photographed, which pervades all religion in every age, and which has been able, under proper circumstances, to materialise back into a temporary solidity so that it could walk and talk like a mortal, whether in Jerusalem two thousand years ago, or in the laboratory of Mr. Crookes, in Mornington Road, London.
 The details of both these latter cases are to be found in "Voices from the Void" by Mrs. Travers Smith, a book containing some well weighed evidence.
Let us for a moment examine the facts in this Crookes' episode. A small book exists which describes them, though it is not as accessible as it should be. In these wonderful experiments, which extended over several years, Miss Florrie Cook, who was a young lady of from 16 to 18 years of age, was repeatedly confined in Prof. Crookes' study, the door being locked on the inside. Here she lay unconscious upon a couch. The spectators assembled in the laboratory, which was separated by a curtained opening from the study. After a short interval, through this opening there emerged a lady who was in all ways different from Miss Cook. She gave her earth name as Katie King, and she proclaimed herself to be a materialised spirit, whose mission it was "to carry the knowledge of immortality to mortals.
She was of great beauty of face, figure, and manner. She was four and a half inches taller than Miss Cook, fair, whereas the latter was dark, and as different from her as one woman could be from another. Her pulse rate was markedly slower. She became for the time entirely one of the company, walking about, addressing each person present, and taking delight in the children. She made no objection to photography or any other test. Forty-eight photographs of different degrees of excellence were made of her. She was seen at the same time as the medium on several occasions. Finally she departed, saying that her mission was over and that she had other work to do. When she vanished materialism should have vanished also, if mankind had taken adequate notice of the facts.
Now, what can the fair-minded inquirer say to such a story as that--one of many, but for the moment we are concentrating upon it? Was Mr. Crookes a blasphemous liar? But there were very many witnesses, as many sometimes as eight at a single sitting. And there are the photographs which include Miss Cook and show that the two women were quite different.
