[Footnote 26: _Quarterly Review_, 1871, pp. 342, 343.] Alas, Dr. Carpenter, when he boldly published (in 1876) the thing that was not, proved that a 'scientist' may be misled by 'moral sources of error'! In 1890, in _Proceedings of the S.P.R._, Sir William Crookes published full contemporary accounts, noted by himself, of his experiments on Home in 1871, with elaborate mechanical tests as to alteration of weights; and recorded Home's feats in handling red-hot coals, and communicating the power of doing so to others, and to a fine cambric handkerchief on which a piece of red-hot charcoal lay some time. Beyond a hole of half an inch in diameter, to which Home drew attention, the cambric was unharmed. Sir William tested it: it had undergone no chemical preparation. Into the details of the mechanical tests as to alterations of weights I cannot go. Mr. Angelo Lewis (Professor Hoffman), an expert in conjuring, says that, accepting Sir William's veracity, and that he was not hallucinated, the phenomena 'seem to me distinctly to be outside the range of trick, and therefore to be good evidence, so far as we can trust personal evidence at all, of Home's power of producing motion, without contact, in inanimate bodies.' Sir William himself writes (1890): 'I have discovered no flaw in the experiments, or in the reasoning I based upon them.'[27] The notes of the performances were written while they were actually in course of proceeding. Thus 'the table rose completely off the ground several times, whilst the gentlemen present took a candle, and, kneeling down, deliberately examined the position of Mr. Home's knees and feet, and saw the three feet of the table quite off the ground.' Every observer in turn satisfied himself of the facts; they could not all be hallucinated. [Footnote 27: _Proceedings S.P.R._ vi. 98.] I have not entered on the 'spiritual' part of the puzzle, the communications from 'spirits' of matters not _consciously_ known to persons present, but found to be correct. That is too large a subject. Nor have I entered into the case of Mrs. Lyon's gift to Home, for the evidence only proved, as the judge held, that the gift was prompted, at least to some extent, by what Home declared to be spiritual rappings. But the only actual witness to the fact, Mrs. Lyon herself, was the reverse of a trustworthy witness, being a foolish capricious underbred woman. Hume's [Transcriber's Note: so in original] mystery, as far as the best of the drawing-room miracles are concerned, is solved by no theory or combination of theories, neither by the hypothesis of conjuring, nor of collective hallucination, nor of a blend of both. The cases of Sir David Brewster and of Dr. Carpenter prove how far some 'scientists' will go, rather than appear in an attitude of agnosticism, of not having a sound explanation.[28]
