“On another occasion he was asked to inspect a house and family, quite unknown to him, in Sloane Street, Chelsea, he being in Edinburgh with a party. He saw in the crystal the family in London; described the house, and also an old gentleman very ill or dying, and wearing a peculiar cap. All was found to be correct, and the cap was one which had lately been sent to the old gentleman. On the same occasion Mr. Lewis told a gentleman present that he had lost or mislaid a key of a very particular shape, which he, Mr. L., saw in the crystal. This was confirmed by the gentleman, a total stranger to Mr. Lewis.” “Sistimus hic tandem.” I think that I have tolerably succeeded in establishing the thesis with which these Letters started, that every superstition is based on a truth; and I am in hopes that the mass of evidence which I have adduced—the very variety of the phenomena described, joined to their mutual coherence—the theoretical consistency of the whole, as if it were truly a vast body of living science, and not the “disjecta membra” of a dream—will remove every remaining shade of doubt among candid readers, that these inquiries are not less sound than they are curious. CONCLUSION. An acquaintance with the facts which it has been the object of the foregoing pages to assemble, and to render into philosophy, suggests one or two serious reflections. We have seen the different results which have ensued when these facts have emerged into day in times of ignorance and in times of enlightenment. On the first occasion they were viewed with terror—became instruments of superstition—were used for bad designs—and even originated new forms of crime, before which common sense fled, and justice became blind and iniquitous. On the latter—I speak of the reception of these facts towards and in the present century—they were recognised by one after another of the most sagacious observers of nature; by Jussieu, for instance, and by Cuvier, to begin with; and gradually by an increasing host of candid, well-informed, and able followers, as forming a part of natural science, and as susceptible of important applications.
