_The Mystery of Joseph Laquedem_, by A. T. Quiller-Couch, is a striking story of dual reincarnation. A young Jew in England and a half-witted girl, a farmer's daughter, recognize in each other and in themselves, the personalities of a young Jew led to the lions for becoming a Christian, and a Roman princess who loved him. They recall their successive lives wherein they have known and loved each other, to be separated by cruel destiny each time, but at last they die a tragic death together. The character of the man here is given additional interest for us in that he is said to be a reincarnation of Cartapholus, Pilate's porter, who struck Jesus, bidding Him go faster, and who is immortalized as the Wandering Jew. Here he lives successive lives rather than a continuous existence. Somewhat similar to this is another combination of hypnotism and metempsychosis in _The Witch of Prague_, by F. Marion Crawford, where Uorna makes Israel Kafka go through the physical and psychical tortures of Simon Abeles, a young Jew killed by his people for becoming a Christian. By hypnotism the young man is made to pass through the experiences of a dead youth of whom he has never heard, and to die his death anew. There is a close relation between dreams and metempsychosis, as is seen in certain stories. Kipling's charming prose idyll, _The Brushwood Boy_, may be called a piece of dream-metempsychosis, for the youth and girl when they first meet in real life recognize in each other the companions of their childhood and adolescent dream-life, and complete their dual memories. They have dreamed the same dreams even to minute details of conversation, and familiar names. Du Maurier combines the two motives very skillfully in his novels, for it is in successive dreams that the Martian reveals herself to Barty Joscelyn telling him of her life on another planet, and inspiring him to write--or writing for him--books of genius, before she takes up earthly life in one of his children. She tells him that she will come to him no more in dreams, but that she will live in the child that is to be born. And in dual dreams Peter Ibbetson and the Duchess of Towers live over again their childhood life together, are able to find at will their golden yesterdays, and know in happy reality the joys of the past, while the present keeps them cruelly apart. They are able to call back to shadowy life their common ancestors, to see and hear the joys, the work, the griefs they knew so long ago. They plumb their sub-consciousness, dream over again their sub-dreams, until they at last not only see these long-dead men and women, but _become_ them. We could each be Gatienne for a space (though not both of us together) and when we resumed our own personality again we carried back with it a portion of hers, never to be lost again--strange phenomenon if the reader will but think of it, and constituting the germ of a comparative personal immortality on earth.
