It might as well be remarked, in conclusion, that the size, and particularly the powers of the man-bats (for example, their ability to fly in so rare an atmosphere—if, indeed, the moon have any), with most of the other fancies in regard to animal and vegetable existence, are at variance, generally, with all analogical reasoning on these themes; and that analogy here will often amount to conclusive demonstration. It is, perhaps, scarcely necessary to add, that all the suggestions attributed to Brewster and Herschel, in the beginning of the article, about “a transfusion of artificial light through the focal object of vision,” etc., etc., belong to that species of figurative writing which comes, most properly, under the denomination of rigmarole.
There is a real and very definite limit to optical discovery among the stars—a limit whose nature need only be stated to be understood. If, indeed, the casting of large lenses were all that is required, man’s ingenuity would ultimately prove equal to the task, and we might have them of any size demanded. But, unhappily, in proportion to the increase of size in the lens, and consequently, of space-penetrating power, is the diminution of light from the object, by diffusion of its rays. And for this evil there is no remedy within human ability; for an object is seen by means of that light alone which proceeds from itself, whether direct or reflected. Thus the only “artificial” light which could avail Mr. Locke, would be some artificial light which he should be able to throw—not upon the “focal object of vision,” but upon the real object to be viewed—to wit: upon the moon. It has been easily calculated that, when the light proceeding from a star becomes so diffused as to be as weak as the natural light proceeding from the whole of the stars, in a clear and moonless night, then the star is no longer visible for any practical purpose.
The Earl of Ross telescope, lately constructed in England, has a speculum with a reflecting surface of .4071 square inches; the Herschel telescope having one of only .1811. The metal of the Earl of Ross’ is 6 feet in diameter; it is 5½ inches thick at the edges, and 5 at the centre. The weight is 3 tons. The focal length is 50 feet.
I have lately read a singular and somewhat ingenious little book, whose title-page runs thus:—“L’Homme dans la lvne, ou le Voyage Chimerique fait au Monde de la Lvne, nouuellement decouuert par Dominique Gonzales, Aduanturier Espagnol, autremèt dit le Courier volant. Mis en notre langve par J. B. D. A. Paris, chez François Piot, pres la Fontaine de Saint Benoist. Et chez J. Goignard, au premier pilier de la grand’ salle du Palais, proche les Consultations, MDCXLVII.” Pp. 176.
The writer professes to have translated his work from the English of one Mr. D’Avisson (Davidson?) although there is a terrible ambiguity in the statement. “I’ en ai eu,” says he, “l’original de Monsieur D’Avisson, medecin des mieux versez qui soient aujourd’huy dans la cònoissance des Belles Lettres, et sur tout de la Philosophie Naturelle. Je lui ai cette obligation entre les autres, de m’auoir non seulement mis en main ce Livre en anglois, mais encore le Manuscrit du Sieur Thomas D’Anan, gentil-homme Eccossois, recommandable pour sa vertu, sur la version duquel j’advoue que j’ay tiré le plan de la mienne.”
After some irrelevant adventures, much in the manner of Gil Blas, and which occupy the first thirty pages, the author relates that, being ill during a sea voyage, the crew abandoned him, together with a negro servant, on the island of St. Helena. To increase the chances of obtaining food, the two separate, and live as far apart as possible. This brings about a training of birds, to serve the purpose of carrier-pigeons between them. By and by these are taught to carry parcels of some weight—and this weight is gradually increased. At length the idea is entertained of uniting the force of a great number of the birds, with a view to raising the author himself. A machine is contrived for the purpose, and we have a minute description of it, which is materially helped out by a steel engraving. Here we perceive the Signor Gonzales, with point ruffles and a huge periwig, seated astride something which resembles very closely a broomstick, and borne aloft by a multitude of wild swans (ganzas) who had strings reaching from their tails to the machine.
The main event detailed in the Signor’s narrative depends upon a very important fact, of which the reader is kept in ignorance until near the end of the book. The ganzas, with whom he had become so familiar, were not really denizens of St. Helena, but of the moon. Thence it had been their custom, time out of mind, to migrate annually to some portion of the earth. In proper season, of course, they would return home; and the author, happening, one day, to require their services for a short voyage, is unexpectedly carried straight up, and in a very brief period arrives at the satellite. Here he finds, among other odd things, that the people enjoy extreme happiness; that they have no law; that they die without pain; that they are from ten to thirty feet in height; that they live five thousand years; that they have an emperor called Irdonozur; and that they can jump sixty feet high, when, being out of the gravitating influence, they fly about with fans.
I cannot forbear giving a specimen of the general philosophy of the volume.
“I must now declare to you,” says the Signor Gonzales, “the nature of the place in which I found myself. All the clouds were beneath my feet, or, if you please, spread between me and the earth. As to the stars, since there was no night where I was, they always had the same appearance; not brilliant, as usual, but pale, and very nearly like the moon of a morning. But few of them were visible, and these ten times larger (as well as I could judge), than they seem to the inhabitants of the earth. The moon which wanted two days of being full, was of a terrible bigness.
“I must not forget here, that the stars appeared only on that side of the globe turned toward the moon, and that the closer they were to it the larger they seemed. I have also to inform you that, whether it was calm weather or stormy, I found myself always immediately between the moon and the earth. I was convinced of this for two reasons—because my birds always flew in a straight line; and because whenever we attempted to rest, we were carried insensibly around the globe of the earth. For I admit the opinion of Copernicus, who maintains that it never ceases to revolve from the east to the west, not upon the poles of the Equinoctial, commonly called the poles of the world, but upon those of the Zodiac, a question of which I propose to speak more at length hereafter, when I shall have leisure to refresh my memory in regard to the astrology which I learned at Salamanca when young, and have since forgotten.”
Notwithstanding the blunders italicized, the book is not without some claim to attention, as affording a naïve specimen of the current astronomical notions of the time. One of these assumed, that the “gravitating power” extended but a short distance from the earth’s surface, and, accordingly, we find our voyager “carried insensibly around the globe,” etc.
There have been other “voyages to the moon,” but none of higher merit than the one just mentioned. That of Bergerac is utterly meaningless. In the third volume of the American Quarterly Review will be found quite an elaborate criticism upon a certain “Journey” of the kind in question;—a criticism in which it is difficult to say whether the critic most exposes the stupidity of the book, or his own absurd ignorance of astronomy. I forget the title of the work; but the means of the voyage are more deplorably ill conceived than are even the ganzas of our friend the Signor Gonzales. The adventurer, in digging the earth, happens to discover a peculiar metal for which the moon has a strong attraction, and straightway constructs of it a box, which, when cast loose from its terrestrial fastenings, flies with him, forthwith, to the satellite. The “Flight of Thomas O’Rourke,” is a jeu d’esprit not altogether contemptible, and has been translated into German. Thomas, the hero, was, in fact, the gamekeeper of an Irish peer, whose eccentricities gave rise to the tale. The “flight” is made on an eagle’s back, from Hungry Hill, a lofty mountain at the end of Bantry Bay.
In these various brochures the aim is always satirical; the theme being a description of Lunarian customs as compared with ours. In none, is there any effort at plausibility in the detail
s of the voyage itself. The writers seem, in each instance, to be utterly uninformed in respect to astronomy. In “Hans Pfaall” the design is original, inasmuch as regards an attempt at verisimilitude, in the application of scientific principles (so far as the whimsical nature of the subject would permit), to the actual passage between the earth and the moon.

1 The zodiacal light is probably what the ancients called Trabes. Emicant Trabes quos docos vocant.—Pliny lib. 2, p. 26.
2 Since the original publication of Hans Pfaall, I find that Mr. Green, of Nassau-balloon notoriety, and other late aëronauts, deny the assertions of Humboldt, in this respect, and speak of a decreasing inconvenience,—precisely in accordance with the theory here urged.
3 Hevelius writes that he has several times found, in skies perfectly clear, when even stars of the sixth and seventh magnitude were conspicuous, that, at the same altitude of the moon, at the same elongation from the earth, and with one and the same excellent telescope, the moon and its maculæ did not appear equally lucid at all times. From the circumstances of the observation, it is evident that the cause of this phenomenon is not either in our air, in the tube, in the moon, or in the eye of the spectator, but must be looked for in something (an atmosphere?) existing about the moon.
Cassini frequently observed Saturn, Jupiter, and the fixed stars, when approaching the moon to occultation, to have their circular figure changed into an oval one; and, in other occultations, he found no alteration of figure at all. Hence it might be supposed, that at some times, and not at others, there is a dense matter encompassing the moon wherein the rays of the stars are refracted.
THE GOLD-BUG
What ho! what ho! this fellow is dancing mad!
He hath been bitten by the Tarantula.
—All in the Wrong
MANY years ago, I contracted an intimacy with a Mr. William Legrand. He was of an ancient Huguenot family, and had once been wealthy; but a series of misfortunes had reduced him to want. To avoid the mortification consequent upon his disasters, he left New Orleans, the city of his forefathers, and took up his residence at Sullivan’s Island, near Charleston, South Carolina.
This island is a very singular one. It consists of little else than the sea sand, and is about three miles long. Its breadth at no point exceeds a quarter of a mile. It is separated from the mainland by a scarcely perceptible creek, oozing its way through a wilderness of reeds and slime, a favorite resort of the marsh-hen. The vegetation, as might be supposed, is scant, or at least dwarfish. No trees of any magnitude are to be seen. Near the western extremity, where Fort Moultrie stands, and where are some miserable frame buildings, tenanted, during summer, by the fugitives from Charleston dust and fever, may be found, indeed, the bristly palmetto ; but the whole island, with the exception of this western point, and a line of hard, white beach on the sea-coast, is covered with a dense undergrowth of the sweet myrtle so much prized by the horticulturists of England. The shrub here often attains the height of fifteen or twenty feet, and forms an almost impenetrable coppice, burthening the air with its fragrance.
In the inmost recesses of this coppice, not far from the eastern or more remote end of the island, Legrand had built himself a small hut, which he occupied when I first, by mere accident, made his acquaintance. This soon ripened into friendship—for there was much in the recluse to excite interest and esteem. I found him well educated, with unusual powers of mind, but infected with misanthropy, and subject to perverse moods of alternate enthusiasm and melancholy. He had with him many books, but rarely employed them. His chief amusements were gunning and fishing, or sauntering along the beach and through the myrtles, in quest of shells or entomological specimens—his collection of the latter might have been envied by a Swammerdamm. In these excursions he was usually accompanied by an old negro, called Jupiter, who had been manumitted before the reverses of the family, but who could be induced, neither by threats nor by promises, to abandon what he considered his right of attendance upon the footsteps of his young “Massa Will.” It is not improbable that the relatives of Legrand, conceiving him to be somewhat unsettled in intellect, had contrived to instil this obstinacy into Jupiter, with a view to the supervision and guardianship of the wanderer.
The winters in the latitude of Sullivan’s Island are seldom very severe, and in the fall of the year it is a rate event indeed when a fire is considered necessary. About the middle of October, 18—, there occurred, however, a day of remarkable chilliness. Just before sunset I scrambled my way through the evergreens to the hut of my friend, whom I had not visited for several weeks—my residence being, at that time, in Charleston, a distance of nine miles from the island, while the facilities of passage and re-passage were very far behind those of the present day. Upon reaching the hut I rapped, as was my custom, and getting no reply, sought for the key where I knew it was secreted, unlocked the door, and went in. A fine fire was blazing upon the hearth. It was a novelty, and by no means an ungrateful one. I threw off an overcoat, took an arm-chair by the crackling logs, and awaited patiently the arrival of my hosts.
Soon after dark they arrived, and gave me a most cordial welcome. Jupiter, grinning from ear to ear, bustled about to prepare some marsh-hens for supper. Legrand was in one of his fits—how else shall I term them?—of enthusiasm. He had found an unknown bivalve, forming a new genus, and, more than this, he had hunted down and secured, with Jupiter’s assistance, a scarabæus which he believed to be totally new, but in respect to which he wished to have my opinion on the morrow.
“And why not to-night?” I asked, rubbing my hands over the blaze, and wishing the whole tribe of scarabæi at the devil.
“Ah, if I had only known you were here!” said Legrand, “but it’s so long since I saw you; and how could I foresee that you would pay me a visit this very night of all others? As I was coming home I met Lieutenant G——, from the fort, and, very foolishly, I lent him the bug; so it will be impossible for you to see it until the morning. Stay here to-night, and I will send Jup down for it at sunrise. It is the loveliest thing in creation!”
“What?—sunrise?”
“Nonsense! no!—the bug. It is of a brilliant gold color—about the size of a large hickory-nut—with two jet black spots near one extremity of the back, and another, somewhat longer, at the other. The antennæ are—”
“Dey aint no tin in him, Massa Will, I keep a tellin’ on you,” here interrupted Jupiter; “de bug is a goole-bug, solid, ebery bit of him, inside and all, sep him wing—neber feel half so hebby a bug in my life.”
“Well, suppose it is, Jup,” replied Legrand, somewhat more earnestly, it seemed to me, than the case demanded; “is that any reason for your letting the birds burn? The color”—here he turned to me—“is really almost enough to warrant Jupiter’s idea. You never saw a more brilliant metallic lustre than the scales emit—but of this you cannot judge till tomorrow. In the meantime I can give you some idea of the shape.” Saying this, he seated himself at a small table, on which were a pen and ink, but no paper. He looked for some in a drawer, but found none.
“Never mind,” he said at length, “this will answer”; and he drew from his waistcoat pocket a scrap of what I took to be very dirty foolscap, and made upon it a rough drawing with the pen. While he did this, I retained my seat by the fire, for I was still chilly. When the design was complete, he handed it to me without rising. As I received it, a loud growl was heard, succeeded by a scratching at the door. Jupiter opened it, and a large Newfoundland, belonging to Legrand, rushed in, leaped upon my shoulders, and loaded me with caresses; for I had shown him much attention during previous visits. When his gambols were over, I looked at the paper, and, to speak the truth, found myself not a little puzzled at what my friend had depicted.
“Well!” I said, after contemplating it for some minutes, “this is a strange scarabæus, I must confess; new to me; never saw any thing like it before—unless it was a skull, or a death’s-head, which it more nearly resembles than any
thing else that has come under my observation.”
“A death’s-head!” echoed Legrand. “Oh—yes—well, it has something of that appearance upon paper, no doubt. The two upper black spots look like eyes, eh? and the longer one at the bottom like a mouth—and then the shape of the whole is oval.”
“Perhaps so,” said I; “but, Legrand, I fear you are no artist. I must wait until I see the beetle itself, if I am to form any idea of its personal appearance.”
“Well, I don’t know,” said he, a little nettled, “I draw tolerably—should do it at least—have had good masters, and flatter myself that I am not quite a blockhead.”
“But, my dear fellow, you are joking then,” said I, “this is a very passable skull—indeed, I may say that it is a very excellent skull, according to the vulgar notions about such specimens of physiology—and your scarabæus must be the queerest scarabæus in the world if it resembles it. Why, we may get up a very thrilling bit of superstition upon this hint. I presume you will call the bug scarabæus caput hominis, or something of that kind—there are many similar titles in the Natural Histories. But where are the antennæ you spoke of?”
“The antennæ!” said Legrand, who seemed to be getting unaccountably warm upon the subject; “I am sure you must see the antennæ. I made them as distinct as they are in the original insect, and I presume that is sufficient.”
