Of the existence of this faculty in nature, any one, who chooses, may satisfy himself by a very moderate degree of trouble, provided he undertake the investigation honestly; and this being granted, another objection, if not altogether removed, is considerably weakened. I allude to the fact that, in numerous reported cases of ghost-seeing, the forms were visible to only one person, even though others were present, which, of course, rendered them undistinguishable from cases of spectral illusion, and indeed unless some additional evidence be afforded, they must remain so still, only we have gained thus much, that this objection is no longer unanswerable; for whether the phenomenon is to be referred to a mutual rapport, or to the opening of the spiritual eye, we comprehend how one may see what others do not. But really, if the seeing depended upon ordinary vision, I can not perceive that the difficulty is insurmountable; for we perfectly well know that some people are endowed with an acuteness of sense, or power of perception, which is utterly incomprehensible to others; for, without entering into the disputed region of clear-seeing, everybody must have met with instances of those strange antipathies to certain objects, accompanied by an extraordinary capacity for perceiving their presence, which remain utterly unexplained. Not to speak of cats and hares, where some electrical effects might be conceived, I lately heard of a gentleman who fainted if he were introduced into a room where there was a raspberry tart; and that there have been persons endowed with a faculty for discovering the proximity of water and metals, even without the aid of the divining rod—which latter marvel seems to be now clearly established as an electrical phenomenon—will scarcely admit of further doubt. A very eminent person, with whom I am acquainted, possessing extremely acute olfactory powers, is the subject of one single exception. He is insensible to the odor of a beanfield, however potent: but it would surely be very absurd in him to deny that the beanfield emits an odor, and the evidence of the majority against him is too strong to admit of his doing so. Now, we have only the evidence of a minority with regard to the existence of certain faculties not generally developed, but surely it argues great presumption to dispute their possibility. We might, I think, with more appearance of reason, insist upon it that my friend _must_ be mistaken, and that he does smell the beanfield, for we have the majority against him there most decidedly. The difference is, that nobody cares whether the odor of the beanfield is perceptible or not: but if the same gentleman asserted that he had seen a ghost, beyond all doubt his word would be disputed.
