[Footnote 203: There is a possible interest in the exact length of the interval. Swoboda (_Die Perioden des Menschlichen Organismus in ihrer psychologischen und biologischen Bedeutung_, 1904) believes that the recurrence of memories tends to obey a law of periodicity, so that, for instance, a melody heard at a concert may recur at a regular interval. I cannot say that I have myself found evidence of such periodicity, though I have made several observations on the recurrence of such memories.] [Footnote 204: Similarly, Foucault (_Le Rêve_, p. 79) records the dream of a lady concerning a place called Brétigny, near Dijon, though when awake she was not aware there is such a place there. Elsewhere (p. 214) Foucault also gives examples of sensations, not consciously perceived in the waking state, but revived in dream. Beaunis, in his interesting 'Contribution à la Psychologie du Rêve' (_American Journal of Psychology_, July-Oct. 1903) narrates a dream of his own in which a forgotten or unconscious memory revived. Many such dreams could easily be brought together. An often-quoted dream, apparently of this kind (see _e.g._, _British Medical Journal_, 7th April 1900, p. 850), is that of Archbishop Benson who, like his predecessor, Laud, took an interest in his dreams. He dreamed that he was suffering severely in his chest, and that his doctor, on being called in, told him that he had angĭna pectoris. The archbishop in his dream exclaimed with indignation: 'Angǐna, angǐna!' The dream made such an impression on him that he looked the matter up, but only found the ordinary pronunciation, angīna, recorded. A week later he was at Cambridge, dining in hall at Trinity, and seated next to Munro, the Professor of Latin, who happened to ask him about the death of Thomas Arnold. 'He died of angĭna pectoris,' said Benson. Munro smiled grimly and said softly: 'Of angǐna, as we now call it.' There can be no doubt that Benson, who was closely in touch with the academic world, had met with this correction, which is accepted by all modern Latinists, and 'forgotten' it.] [Footnote 205: Xenoglossia, as well as the tendency to utter gibberish, are both classed under glossolalia. See _e.g._ E. Lombard, 'Phenomènes de Glossolalie,' _Archives de Psychologie_, July 1907.] [Footnote 206: In the eighteenth century Lord Monboddo (_Ancient Metaphysics_, vol. iii., 1782, p. 217) referred to a Countess of Laval who, during the delirium of illness, spoke the Breton tongue which she had known as a child, but long since forgotten.]
