roughened as to have the appearance of being stuck full of splinters — but then I distinctly recollected that there were some of them which were not disfigured at all. Now I could not account for this difference except by supposing that the roughened fragments were the only ones which had been completely absorbed— that the others had entered the whirl at so late a period of the tide, or, for some reason, had descended so slowly after entering, that they did not reach the bottom before the turn of the flood came, or of the ebb, as the case might be. I conceived it possible, in either instance, that they might thus be whirled up again to the level of the ocean, without undergoing the fate of those which had been drawn in more early, or absorbed more rapidly. I made, also, three important observations. The first was, that, as a general rule, the larger the bodies were, the more rapid their descent — the second, that, between two masses of equal extent, the one spherical, and the other of any other shape, the superiority in speed of descent was with the sphere — the third, that, between two masses of equal size, the one cylindrical, and the other of any other shape, the cylinder was absorbed the more slowly. Since my escape, I have had several conversations on this subject with an old school-master of the district; and it was from him that I learned the use of the words ‘cylinder’ and ‘sphere.’ He explained to me — although I have forgotten the explanation — how what I observed was, in fact, the natural consequence of the forms of the floating fragments — and showed me how it happened that a cylinder, swimming in a vortex, offered more resistance to its suction, and was drawn in with greater difficulty than an equally bulky body, of any form whatever. (*1)

      “There was one startling circumstance which went a great way in enforcing these observations, and rendering me anxious to turn them to account, and this was that, at every revolution, we passed something like a barrel, or else the yard or the mast of a vessel, while many of these things, which had been on our level when I first opened my eyes upon the wonders of the whirlpool, were now high up above us, and seemed to have moved but little from their original station.

      “I no longer hesitated what to do. I resolved to lash myself securely to the water cask upon which I now held, to cut it loose from the counter, and to throw myself with it into the water. I attracted my brother’s attention by signs, pointed to the floating barrels that came near us, and did everything in my power to make him understand what I was about to do. I thought at length that he comprehended my design — but, whether this was the case or not, he shook his head despairingly, and refused to move from his station by the ring-bolt. It was impossible to reach him; the emergency admitted of no delay; and so, with a bitter struggle, I resigned him to his fate, fastened myself to the cask by means of the lashings which secured it to the counter, and precipitated myself with it into the sea, without another moment’s hesitation.

      “The result was precisely what I had hoped it might be. As it is myself who now tell you this tale — as you see that I did escape — and as you are already in possession of the mode in which this escape was effected, and must therefore anticipate all that I have farther to say — I will bring my story quickly to conclusion. It might have been an hour, or thereabout, after my quitting the smack, when, having descended to a vast distance beneath me, it made three or four wild gyrations in rapid succession, and, bearing my loved brother with it, plunged headlong, at once and forever, into the chaos of foam below. The barrel to which I was attached sunk very little farther than half the distance between the bottom of the gulf and the spot at which I leaped overboard, before a great change took place in the character of the whirlpool. The slope of the sides of the vast funnel became momently less and less steep. The gyrations of the whirl grew, gradually, less and less violent. By degrees, the froth and the rainbow disappeared, and the bottom of the gulf seemed slowly to uprise. The sky was clear, the winds had gone down, and the full moon was setting radiantly in the west, when I found myself on the surface of the ocean, in full view of the shores of Lofoden, and above the spot where the pool of the Moskoe-ström had been. It was the hour of the slack — but the sea still heaved in mountainous waves from the effects of the hurricane. I was borne violently into the channel of the Ström, and in a few minutes was hurried down the coast into the ‘grounds’ of the fishermen. A boat picked me up — exhausted from fatigue — and (now that the danger was removed) speechless from the memory of its horror. Those who drew me on board were my old mates and daily companions — but they knew me no more than they would have known a traveller from the spirit-land. My hair which had been raven-black the day before, was as white as you see it now. They say too that the whole expression of my countenance had changed. I told them my story — they did not believe it. I now tell it to you— and I can scarcely expect you to put more faith in it than did the merry fishermen of Lofoden.”

      VON KEMPELEN AND HIS DISCOVERY

      AFTER THE very minute and elaborate paper by Arago, to say nothing of the summary in ‘Silliman’s Journal,’ with the detailed statement just published by Lieutenant Maury, it will not be supposed, of course, that in offering a few hurried remarks in reference to Von Kempelen’s discovery, I have any design to look at the subject in a scientific point of view. My object is simply, in the first place, to say a few words of Von Kempelen himself (with whom, some years ago, I had the honor of a slight personal acquaintance), since every thing which concerns him must necessarily, at this moment, be of interest; and, in the second place, to look in a general way, and speculatively, at the results of the discovery.

      It may be as well, however, to premise the cursory observations which I have to offer, by denying, very decidedly, what seems to be a general impression (gleaned, as usual in a case of this kind, from the newspapers), viz.: that this discovery, astounding as it unquestionably is, is unanticipated.

      By reference to the ‘Diary of Sir Humphrey Davy’ (Cottle and Munroe, London, pp. 150), it will be seen at pp. 53 and 82, that this illustrious chemist had not only conceived the idea now in question, but had actually made no inconsiderable progress, experimentally, in the very identical analysis now so triumphantly brought to an issue by Von Kempelen, who although he makes not the slightest allusion to it, is, without doubt (I say it unhesitatingly, and can prove it, if required), indebted to the ‘Diary’ for at least the first hint of his own undertaking.

      The paragraph from the ‘Courier and Enquirer,’ which is now going the rounds of the press, and which purports to claim the invention for a Mr. Kissam, of Brunswick, Maine, appears to me, I confess, a little apocryphal, for several reasons; although there is nothing either impossible or very improbable in the statement made. I need not go into details. My opinion of the paragraph is founded principally upon its manner. It does not look true. Persons who are narrating facts, are seldom so particular as Mr. Kissam seems to be, about day and date and precise location. Besides, if Mr. Kissam actually did come upon the discovery he says he did, at the period designated — nearly eight years ago — how happens it that he took no steps, on the instant, to reap the immense benefits which the merest bumpkin must have known would have resulted to him individually, if not to the world at large, from the discovery? It seems to me quite incredible that any man of common understanding could have discovered what Mr. Kissam says he did, and yet have subsequently acted so like a baby — so like an owl — as Mr. Kissam admits that he did. By-the-way, who is Mr. Kissam? and is not the whole paragraph in the ‘Courier and Enquirer’ a fabrication got up to ‘make a talk’? It must be confessed that it has an amazingly moon-hoaxy-air. Very little dependence is to be placed upon it, in my humble opinion; and if I were not well aware, from experience, how very easily men of science are mystified, on points out of their usual range of inquiry, I should be profoundly astonished at finding so eminent a chemist as Professor Draper, discussing Mr. Kissam’s (or is it Mr. Quizzem’s?) pretensions to the discovery, in so serious a tone.

      But to return to the ‘Diary’ of Sir Humphrey Davy. This pamphlet was not designed for the public eye, even upon the decease of the writer, as any person at all conversant with authorship may satisfy himself at once by the slightest inspection of the style. At page 13, for example, near the middle, we read, in reference to his researches about the protoxide of azote: ‘In less than half a minute the respiration being continued, diminished gradually and were succeeded by analogous to gentle pressure on all the muscles.’ That the respiration was not ‘diminished,’ is not only clear by the subsequent context, but by
