(*1) NOTE—Strictly speaking, there is but little similarity between the above sketchy trifle and the celebrated “Moon-Story” of Mr. Locke; but as both have the character of hoaxes (although the one is in a tone of banter, the other of downright earnest), and as both hoaxes are on the same subject, the moon—moreover, as both attempt to give plausibility by scientific detail—the author of “Hans Pfaall” thinks it necessary to say, in self-defence, that his own jeu d’esprit was published in the “Southern Literary Messenger” about three weeks before the commencement of Mr. L’s in the “New York Sun.” Fancying a likeness which, perhaps, does not exist, some of the New York papers copied “Hans Pfaall,” and collated it with the “Moon-Hoax,” by way of detecting the writer of the one in the writer of the other.

As many more persons were actually gulled by the “Moon-Hoax” than would be willing to acknowledge the fact, it may here afford some little amusement to show why no one should have been deceived-to point out those particulars of the story which should have been sufficient to establish its real character. Indeed, however rich the imagination displayed in this ingenious fiction, it wanted much of the force which might have been given it by a more scrupulous attention to facts and to general analogy. That the public were misled, even for an instant, merely proves the gross ignorance which is so generally prevalent upon subjects of an astronomical nature.

The moon’s distance from the earth is, in round numbers, 240,000 miles. If we desire to ascertain how near, apparently, a lens would bring the satellite (or any distant object), we, of course, have but to divide the distance by the magnifying or, more strictly, by the space-penetrating power of the glass. Mr. L. makes his lens have a power of 42,000 times. By this divide 240,000 (the moon’s real distance), and we have five miles and five sevenths, as the apparent distance. No animal at all could be seen so far; much less the minute points particularized in the story. Mr. L. speaks about Sir John Herschel’s perceiving flowers (the Papaver rheas, etc.), and even detecting the color and the shape of the eyes of small birds. Shortly before, too, he has himself observed that the lens would not render perceptible objects of less than eighteen inches in diameter; but even this, as I have said, is giving the glass by far too great power. It may be observed, in passing, that this prodigious glass is said to have been molded at the glasshouse of Messrs. Hartley and Grant, in Dumbarton; but Messrs. H. and G.‘s establishment had ceased operations for many years previous to the publication of the hoax.

On page 13, pamphlet edition, speaking of “a hairy veil” over the eyes of a species of bison, the author says: “It immediately occurred to the acute mind of Dr. Herschel that this was a providential contrivance to protect the eyes of the animal from the great extremes of light and darkness to which all the inhabitants of our side of the moon are periodically subjected.” But this cannot be thought a very “acute” observation of the Doctor’s. The inhabitants of our side of the moon have, evidently, no darkness at all, so there can be nothing of the “extremes” mentioned. In the absence of the sun they have a light from the earth equal to that of thirteen full unclouded moons.

The topography throughout, even when professing to accord with Blunt’s Lunar Chart, is entirely at variance with that or any other lunar chart, and even grossly at variance with itself. The points of the compass, too, are in inextricable confusion; the writer appearing to be ignorant that, on a lunar map, these are not in accordance with terrestrial points; the east being to the left, etc.

Deceived, perhaps, by the vague titles, Mare Nubium, Mare Tranquillitatis, Mare Faecunditatis, etc., given to the dark spots by former astronomers, Mr. L. has entered into details regarding oceans and other large bodies of water in the moon; whereas there is no astronomical point more positively ascertained than that no such bodies exist there. In examining the boundary between light and darkness (in the crescent or gibbous moon) where this boundary crosses any of the dark places, the line of division is found to be rough and jagged; but, were these dark places liquid, it would evidently be even.

The description of the wings of the man-bat, on page 21, is but a literal copy of Peter Wilkins’ account of the wings of his flying islanders. This simple fact should have induced suspicion, at least, it might be thought.

On page 23, we have the following: “What a prodigious influence must our thirteen times larger globe have exercised upon this satellite when an embryo in the womb of time, the passive subject of chemical affinity!” This is very fine; but it should be observed that no astronomer would have made such remark, especially to any journal of Science; for the earth, in the sense intended, is not only thirteen, but forty-nine times larger than the moon. A similar objection applies to the whole of the concluding pages, where, by way of introduction to some discoveries in Saturn, the philosophical correspondent enters into a minute schoolboy account of that planet—this to the “Edinburgh journal of Science!”

But there is one point, in particular, which should have betrayed the fiction. Let us imagine the power actually possessed of seeing animals upon the moon’s surface—what would first arrest the attention of an observer from the earth? Certainly neither their shape, size, nor any other such peculiarity, so soon as their remarkable situation. They would appear
