John Weeks Moore, Complete Encyclopaedia of Music… (1880)
“ When these strings are in unison, and the instrument exposed in the window to the action of a gentle breeze, they will emit the most agreeable combination of wild and melting sounds, changing from one harmonic of the string to another, according to the varying impulse of wind, and its unequal action on the different parts of the vibrating strings. In the Aeolian harp constructed by the Rev. W. Jones, the strings, instead of being on the outside, are fastened to a sounding board within a wooden case, and the wind is conveyed to the strings through a horizontal aperture. ”
