[Footnote 268: See _e.g._, De Manacéïne, _Sleep_, p. 314; Arturo Morselli, 'Dei Sogni nei Genii,' _La Cultura_, 1899.] [Footnote 269: Thus I once planned in a dream a paper on the Progress of Psychology, which seemed to me on awakening to present a quite workable though not notably brilliant scheme.] [Footnote 270: Sante de Sanctis, however (_I Sogni_, p. 369), reproduces a dream poem of twelve lines.] [Footnote 271: See note in J. D. Campbell's edition of Coleridge's _Poetical Works_, p. 592.] [Footnote 272: Tartini composed the sonata--a noble and beautiful work which still survives--at the age of twenty-one. In old age he told Lalande the astronomer (as the latter relates in his _Voyage d'un Français en Italie_, 1765, vol. ix. p. 55) that he had had a dream in which he sold his soul to the Devil, and it occurred to him in his dream to hand his fiddle to the Devil to see what he could do with it. 'But how great was my astonishment when I heard him play with consummate skill a sonata of such exquisite beauty as surpassed the boldest flights of my imagination. I felt enraptured, transported, enchanted; my breath was taken away, and I awoke. Seizing my violin I tried to retain the sounds I had heard. But it was in vain. The piece I then composed, the "Devil's Sonata," was the best I ever wrote, but how far below the one I had heard in my dream!' The dream, it will be seen, was of a fairly common type, and to Tartini's excitable temperament it served as a stimulus to his finest energies. But the real 'Devil's Sonata' was hopelessly lost. (See the articles on Tartini in Fetis, _Biographic Universelle des Musiciens_, and Grove's _Dictionary of Music and Musicians_.)] [Footnote 273: Helen Keller, the blind deaf-mute, has written some interesting chapters on her dreams in _The World I Live in_. For the most part it would seem that the dream life of the blind (which has been studied by, among others, Jastrow, _Fact and Fable in Psychology_, pp. 337 _et seq._) is not usually rich or vivid.] [Footnote 274: See _e.g._, Marie de Manacéïne, _Sleep_, p. 313.]
