M. le due d'Orleans, surprised that she had never

mentioned Monseigneur, Monsieur le due de Bour- gogne, Madame la duchesse de Bourgogne, nor M. le due de Berri, inquired if she did not see such and such people answering to their description. She persisted that she did not, and went over the others for the second time. This astonished M. le due d'Orleans deeply, as well as myself, and we were at a loss to explain it, but the event proved that the child was perfectly right. This seance took place in 1706. These four members of the royal family were then full of health and strength ; and they all died before the king. It was the same thing with M. le prince, M. le due, and M. le prince de Conti, whom she likewise did not see, though she beheld the children of the two last named ; M. du Maine, his own (Orleans), and M. le comte de Toulouse. But of course this fact was unknown till eight years after."
Science may conceivably come to study crystal visions, but veracious crystal visions will be treated like veracious dreams. That is to say, they will be explained as the results of a chance coincidence between the unknown fact and the vision, or of imposture, conscious or unconscious, or of confusion

Thus a vast number of wel authenticated cases of veracious visions will required before science could admit that it mig be well to investigate hitherto unacknowledged faculties of the human mind. The evidence can never be other than the word of the seer, with what- ever value may attach to the testimony of those for whom he "sees," and describes, persons and places unknown to himself. The evidence of in- dividuals as to their own subjective experiences is accepted by psychologists in other departments of the study.^
1 Readers curious in crystal-gazing will find an interesting sketch of the history of the practice, with many modern instances, in Proceedings, S.P.R., vol. v., p. 486, by " Miss X.". There are also experiments by Lord Stanhope and Dr. Gregory in Gregory's Letters on Animal Magnetism, p. 370 (1851). It is said that, as sights may be seen in a glass ball, so articulate voices, by a similar illusion, can be heard in a sea shell, when
" It remembers its august abodes, And murmurs as the ocean murmurs there".
