Very similar to Miss Cook's mediumship was that of Miss Showers; a young lady whom I have met frequently at the house of a lady at the West-end of London, both the medium and her hostess being quite above suspicion. In this case, besides the face and full form we have singing in a clear baritone voice presumably by a spirit called Peter--who gives himself out as having been in earth-life, I believe, a not very estimable specimen of a market-gardener. I am exceedingly puzzled how to account for these things. I dare not suspect the medium; but even granting the truth of the manifestations, they seem to me to be of a low class which one would only come into contact with under protest and for the sake of evidence. Mr. Crookes used to explain, and Serjeant Cox still explains these manifestations as being the products of a so-called Psychic Force--a term which I below define. Although I am as little inclined to hero-worship, and care as little for large names as any man living, yet it is quite impossible not to attach importance to the testimony of these gentlemen; one so eminent in the scientific world, and privileged to write himself F.R.S., the other trained to weigh evidence and decide between balanced probabilities. But it would seem that while Psychic Force might cover the ground of my earlier experiences, it singularly fails to account for the materializations, and obliges us to relegate them to the category of fraud, unless we accept them as being what they profess to be. This I believe Serjeant Cox ruthlessly does. He claims as we have seen to have "caught" Miss Showers, and was not, I believe, convinced by Miss Cook. Mr. Crookes was: and, when we remember that Mr. Wallace, the eminent naturalist, and Mr. Cromwell Varley, the electrician, both accept the spiritual theory, it really looks as though the scientific mind was more open to receive--perhaps driven to receive--this which I frankly concede to be the only adequate cause for the effects, while the legal mind still remains hair-splitting upon conflicting evidence. Whereabouts the theological mind is I do not quite know--perhaps still dangling between the opposite poles of Faith and Reason, and dubiously debating with me "Am I a Spiritualist or not?" In a recent pamphlet reprinted from the Quarterly Journal of Science, Mr. Crookes thus compendiously sums up the various theories which have been invented to account for spiritualistic phenomena, and, in so doing, incidentally defines his now discarded theory of Psychic Force which owns Mr. Serjeant Cox for its patron:-- _First Theory._--The phenomena are all the results of tricks, clever mechanical arrangements, or legerdemain; the mediums are impostors, and the rest of the company fools.
