It is noteworthy that there is little experimental evidence for the transmission of an auditory impression. Occasionally, in trials with names and cards the nature of the mistakes made has seemed to indicate audition, as when, _e.g._, _three_ is given for _Queen_ or _ace_ for _eight_. But obviously a long series of experiments and a long series of mistakes would be necessary to afford material for any conclusion. Sometimes a percipient has stated that he heard the name of the thing thought of; as, for instance, in a case recorded in Chapter V., where the percipient "heard" the word _gloves_ before "seeing" a vision of them. But such cases appear to be rare. Experiments with a view to test the transmission of _actual_ sounds could of course only be carried out under special conditions, of which one would be the separation of the agent from the percipient by a considerable intervening space--and this condition is, of itself, found to interfere with success. Some evidence, indeed, of a quasi-experimental character for the transference of musical sounds at a distance will be given in a later chapter (Chapter V., No. 33). Experiments with imagined sounds appear to have been rarely tried, or at least, successful results have rarely been recorded.[16] Occasionally indeed experimenters have put on record that in thinking of an object they have mentally repeated the name of the object as well as pictured the object itself, and there are a few cases where the general idea of the object thought of appears to have reached the percipient before the outlines of the form, which may possibly be explained as due to the reception of an auditory before a visual impression.[17]
