Now for an exemplification of this marvellous phenomenon. Being at Boppard, a letter of mine addressed to a friend in Paris was by him put into the hands of M. Alexis, who was asked to describe me. M. Alexis told at once my age and stature, my disposition, and my illness; how that I am entirely crippled, and at that time of the day, half-past eleven, A.M. was in bed. All this, to be sure, M. Alexis might have read in my friend’s mind, without going farther. But, he added, this gentleman lives on the sea-coast. My friend denied the assertion; but M. Alexis continued very positive that he was right. Now, most oddly, the Rhine, on the banks of which I resided then, is at Boppard the boundary of Prussia; and I never cross it, or visit Nassau, but I am in the habit of sitting on the bank, listening to the breaking of the surge, which the passing steamers create, and which exactly resembles the murmur of the sea. This very mistake of M. Alexis helped to convince me that this performance of his was genuine. However, being stoutly contradicted by my friend, M. Alexis reconsidered the matter, and said, “No; he does not live on the sea-coast, but on the Rhine, twenty leagues from Frankfort.” This answer was exact. But there was another point which M. Alexis hit with curious felicity. I should observe that this friend was one of a few months’ date, who had no means of comparing what I am with what I was formerly. But it had happened that I had written, not to him, but to a friend resident in England, _about the same time_, that, ill as I was, my mind was singularly clear and active, and that I regarded the fact as a sign my end was at hand; that the mental brightness probably resembled the flaring-up of a rushlight before it goes out. Well, M. Alexis, adverting to my condition, observed that I was extremely weak, and had suffered much from irritation of the nerves;—facts true enough, but which certainly would not have led him to infer the existence of that clearness of mind which I had myself remarked. Nevertheless, strangely added M. Alexis, “Le morale n’en est pas atteint; au contraire, l’esprit est plus dégagé et plus vif qu’auparavant.” I can therefore entertain no doubt, that at four hundred miles’ distance, merely by handling a recent letter from me, M. Alexis had identified me as its writer, through the Od-fluid the letter conveyed; and had truly penetrated my physical and mental being so completely, that most that was important in my story lay distinctly revealed before him. * * * * * VII. _Mental Travelling by clairvoyantes._—Let me begin with an instance. The following extract from the _Zoist_ contains a very interesting narrative by Lord Ducie, which is exactly to the point:
