We did not think at our last leave-taking that Miss Porter’s fragile frame could have so long withstood the Power that takes away all we hold most dear; but her spirit was at length summoned, after a few days’ total insensibility, on the 24th of May.

We were haunted by the idea that the pretty cottage at Esher, where we spent those happy hours, had been treated even as “Mrs. Porter’s Arcadia” at Thames Ditton – now altogether removed; and it was with a melancholy pleasure we found it the other morning in nothing changed; it was almost impossible to believe that so many years had passed since our last visit. While Mr. Fairholt was sketching the cottage, we knocked at the door, and were kindly permitted by two gentle sisters, who now inhabit it, to enter the little drawing-room and walk round the garden; except that the drawing-room has been re-papered and painted, and that there were no drawings and no flowers, the room was not in the least altered; yet to us it seemed like a sepulchre, and we rejoiced to breathe the sweet air of the little garden, and listen to a nightingale, whose melancholy cadence harmonized with our feelings.

“Whenever you are at Esher,” said the devoted daughter, the last time we conversed with her, “do visit my mother’s tomb.” We did so. A cypress flourishes at the head of the grave; and the following touching inscription is carved on the stone:

SHOOTING STARS AND METEORIC SHOWERS

From every region of the globe and in all ages of time within the range of history, exhibitions of apparent instability in the heavens have been observed, when the curtains of the evening have been drawn. Suddenly, a line of light arrests the eye, darting like an arrow through a varying extent of space, and in a moment the firmament is as sombre as before. The appearance is exactly that of a star falling from its sphere, and hence the popular title of shooting star applied to it. The apparent magnitudes of these meteorites are widely different, and also their brilliancy. Occasionally, they are far more resplendent than the brightest of the planets, and throw a very perceptible illumination upon the path of the observer. A second or two commonly suffices for the individual display, but in some instances it has lasted several minutes. In every climate it is witnessed, and at all times of the year, but most frequently in the autumnal months. As far back as records go, we meet with allusions to these swift and evanescent luminous travelers. Minerva’s hasty flight from the peaks of Olympus to break the truce between the Greeks and Trojans, is compared by Homer to the emission of a brilliant star. Virgil, in the first book of the Georgics, mentions the shooting stars as prognosticating weather changes:

“And on, before tempestuous winds arise,The seeming stars fall headlong from the skies,And, shooting through the darkness, gild the nightWith sweeping glories and long trains of light.”

Various hypotheses have been framed to explain the nature and origin of these remarkable appearances. When electricity began to be understood, this was thought to afford a satisfactory explanation, and the shooting stars were regarded by Beccaria and Vassali as merely electrical sparks. When the inflammable nature of the gases became known, Lavosier and Volta supposed an accumulation of hydrogen in the higher regions of the atmosphere, because of its inferior density, giving rise by ignition to the meteoric exhibitions. While these theories of the older philosophers have been shown to be untenable, there is still great obscurity resting upon the question, though we have reason to refer the phenomena to a cause exterior to the bounds of our atmosphere. Upon this ground, the subject assumes a strictly astronomical aspect, and claims a place in a treatise on the economy of the solar system.

The first attempt accurately to investigate these elegant meteors was made by two university students, afterward Professors Brandes of Leipsic, and Benzenberg of Dusseldorf, in the year 1798. They selected a base line of 46,200 feet, somewhat less than nine English miles, and placed themselves at its extremities on appointed nights, for the purpose of ascertaining their average altitude and velocity. Out of twenty-two appearances identified as the same, they found,

7 under 45 miles

9 between 45 and 90 miles

5 above 90 miles

1 above 140 miles.

The greatest observed velocity gave twenty-five miles in a second. A more extensive plan was organized by Brandes in the year 1823, and carried into effect in the neighborhood of Breslaw. Out of ninety-eight appearances, the computed heights were,

4 under 15 miles

15 from 15 to 30 miles

22 from 30 to 45 miles

33 from 45 to 70 miles

13 from 70 to 90 miles

6 above 90 miles

5 from 140 to 460 miles.

The velocities were between eighteen and thirty-six miles in a second, an average velocity far greater than that of the earth in its orbit.

The rush of luminous bodies through the sky of a more extraordinary kind, though a rare occurrence, has repeatedly been observed. They are usually discriminated from shooting stars, and known by the vulgar as fire-balls; but probably both proceed from the same cause, and are identical phenomena. They have sometimes been seen of large volume, giving an intense light, a hissing noise accompanying their progress, and a loud explosion attending their termination. In the year 1676, a meteor passed over Italy about two hours after sunset, upon which Montanari wrote a treatise. It came over the Adriatic Sea as if from Dalmatia, crossed the country in the direction of Rimini and Leghorn, a loud report being heard at the latter place, and disappeared upon the sea toward Corsica. A similar visitor was witnessed all over England, in 1718, and forms the subject of one of Halley’s papers to the Royal Society. Sir Hans Sloane was one of its spectators. Being abroad at the time of its appearance, at a quarter past eight at night, in the streets of London, his path was suddenly and intensely illuminated. This, he apprehended at first, might arise from a discharge of rockets; but found a fiery object in the heavens, moving after the manner of a falling star, in a direct line from the Pleiades to below the girdle of Orion. Its brightness was so vivid, that several times he was obliged to turn away his eyes from it. The stars disappeared, and the moon, then nine days old, and high near the meridian, the sky being very clear, was so effaced by the lustre of the meteor as to be scarcely seen. It was computed to have passed over three hundred geographical miles in a minute, at the distance of sixty miles above the surface, and was observed at different extremities of the kingdom. The sound of an explosion was heard through Devon and Cornwall, and along the opposite coast of Bretagne. Halley conjectured this and similar displays to proceed from combustible vapors aggregated on the outskirts of the atmosphere, and suddenly set on fire by some unknown cause. But since his time, the fact has been established, of the actual fall of heavy bodies to the earth from surrounding space, which requires another hypothesis. To these bodies the term aërolites is applied, signifying atmospheric stones, from αηρ, the atmosphere, and λιθος, a stone. While many meteoric appearances may simply arise from electricity, or from the inflammable gases, it is now certain, from the proved descent of aërolites, that such bodies are of extra-terrestrial origin.

Antiquity refers us to several objects as having descended from the skies, the gifts of the immortal gods. Such was the Palladium of Troy, the image of the goddess of Ephesus, and the sacred shield of Numa. The folly of the ancients in believing such narrations has often been the subject of remark; but, however fabulous the particular cases referred to, the moderns have been compelled to renounce their skepticism respecting the fact itself, of the actual transition of substances from celestial space to terrestrial regions; and no doubt the ancient faith upon this subject was founded on observed events. The following table, taken from the work of M. Izarn, Des Pierres tombées du Ciel, exhibits a collection of instances of the fall of aërolites, together with the eras of their descent, and the persons on whose evidence the facts rest; but the list might be largely extended.

Some of the instances in the table are of sufficient interest to deserve a notice.

A singular relation respecting the stone of Ensisheim on the Rhine, at which philosophy once smiled incredulously, regarding it as one of the romances of the middle ages, may now be admitted to sober attention as a piece of authentic history. A homely narrative of its fall was drawn up at the time by order of the Emperor Maximilian, and deposited with the stone in the church. It may thus be rendered: “In the year of the Lord 1492, on Wednesday, which was Martinmas eve, the 7th of November, a singular miracle occurred; for, between eleven o’clock and noon, there was a loud clap of thunder, and a prolonged confused noise, which was heard at a great distance; and a stone fell from the air, in the jurisdiction of Ensisheim, which weighed two hundred and sixty pounds, and the confused noise was, besides, much louder than here. Then a child saw it strike on a field in the upper jurisdiction, toward the Rhine and Inn, near the district of Giscano, which was sown with wheat, and it did it no harm, except that it made a hole there: and then they conveyed it from that spot; and many pieces were broken from it; which the landvogt forbade. They, therefore, caused it to be placed in the church, with the intention of suspending it as a miracle: and there came here many people to see this stone. So there were remarkable conversations about this stone: but the learned said that they knew not what it was; for it was beyond the ordinary course of nature that such a large stone should smite the earth from the height of the air; but that it was really a miracle of God; for, before that time, never any thing was heard like it, nor seen, nor described. When they found that stone, it had entered into the earth to the depth of a man’s stature, which every body explained to be the will of God that it should be found; and the noise of it was heard at Lucerne, at Vitting, and in many other places, so loud that it was believed that houses had been overturned: and as the King Maximilian was here the Monday after St. Catharine’s day of the same year, his royal excellency ordered the stone which had fallen to be brought to the castle, and, after having conversed a long time about it with the noblemen, he said that the people of Ensisheim should take it, and order it to be hung up in the church, and not to allow any body to take any thing from it. His excellency, however, took two pieces of it; of which he kept one, and sent the other to the Duke Sigismund of Austria: and they spoke a great deal about this stone, which they suspended in the choir, where it still is; and a great many people came to see it.” Contemporary writers confirm the substance of this narration, and the evidence of the fact exists; the aërolite is precisely identical in its chemical composition with that of other meteoric stones. It remained for three centuries suspended in the church, was carried off to Colmar during the French revolution; but has since been restored to its former site, and Ensisheim rejoices in the possession of the relic. A piece broken from it is in the Museum of the Jardin des Plantes at Paris.

The celebrated Gassendi was an eye-witness of a similar event. In the year 1627, on the 27th of November, the sky being quite clear, he saw a burning stone fall in the neighborhood of Nice, and examined the mass. While in the air it appeared to be about four feet in diameter, was surrounded by a luminous circle of colors like a rainbow, and its fall was accompanied by a noise like the discharge of artillery. Upon inspecting the substance, he found it weighed 59 lbs., was extremely hard, of a dull, metallic color, and of a specific gravity considerably greater than that of common marble. Having only this solitary instance of such an occurrence, Gassendi concluded that the mass came from some of the mountains of Provence, which had been in a transient state of volcanic activity. Instances of the same phenomenon occurred in the years 1672, 1756, and 1768; but the facts were generally doubted by naturalists, and considered as electrical appearances, magnified by popular ignorance and timidity. A remarkable example took place in France in the year 1790. Between nine and ten o’clock at night, on the 24th of July, a luminous ball was seen traversing the atmosphere with great rapidity, and leaving behind it a train of light; a loud explosion was then heard, accompanied with sparks which flew off in all directions; this was followed by a shower of stones over a considerable extent of ground, at various distances from each other, and of different sizes. A procès verbal was drawn up, attesting the circumstance, signed by the magistrates of the municipality, and by several hundreds of persons inhabiting the district. This curious document is literally as follows: “In the year one thousand seven hundred and ninety, and the thirtieth day of the month of August, we, the Lieut. Jean Duby, mayor, and Louis Massillon, procurator of the commune of the municipality of La Grange-de-Juillac, and Jean Darmite, resident in the parish of La Grange-de-Juillac, certify in truth and verity, that on Saturday, the 24th of July last, between nine and ten o’clock, there passed a great fire, and after it we heard in the air a very loud and extraordinary noise; and about two minutes after there fell stones from heaven; but fortunately there fell only a very few, and they fell about ten paces from one another in some places, and in others nearer, and, finally, in some other places farther; and falling, most of them, of the weight of about half a quarter of a pound each, some others of about half a pound, like that found in our parish of La Grange; and on the borders of the parish of Creon, they were found of a pound weight; and in falling, they seemed not to be inflamed, but very hard and black without, and within of the color of steel: and, thank God, they occasioned no harm to the people, nor to the trees, but only to some tiles which were broken on the houses; and most of them fell gently, and others fell quickly, with a hissing noise; and some were found which had entered into the earth, but very few. In witness thereof, we have written and signed these presents. Duby, mayor. Darmite.” Though such a document as this, coming from the unlearned of the district where the phenomenon occurred, was not calculated to win acceptance with the savans of the French capital, yet it was corroborated by a host of intelligent witnesses at Bayonne, Thoulouse, and Bordeaux, and by transmitted specimens containing the substances usually found in atmospheric stones, and in nearly the same proportions. A few years afterward, an undoubted instance of the fall of an aërolite occurred in England, which largely excited public curiosity. This was in the neighborhood of Wold Cottage, the house of Captain Topham, in Yorkshire. Several persons heard the report of an explosion in the air, followed by a hissing sound; and afterward felt a shock, as if a heavy body had fallen to the ground at a little distance from them. One of these, a plowman, saw a huge stone falling toward the earth, eight or nine yards from the place where he stood. It threw up the mould on every side, and after penetrating through the soil, lodged some inches deep in solid chalk rock. Upon being raised, the stone was found to weigh fifty-six pounds. It fell in the afternoon of a mild but hazy day, during which there was no thunder or lightning; and the noise of the explosion was heard through a considerable district. It deserves remark, that in most recorded cases of the descent of projectiles, the weather has been settled, and the sky clear; a fact which plainly places them apart from the causes which operate to produce the tempest, and shows the popular term thunder-bolt to be an entire misnomer.

While this train of circumstances was preparing the philosophic mind of Europe to admit as a truth what had hitherto been deemed a vulgar error, and acknowledge the appearance of masses of ignited matter in the atmosphere occasionally descending to the earth, an account of a phenomenon of this kind was received from India, vouched by an authority calculated to secure it general respect. It came from Mr. Williams, F.R.S., a resident in Bengal. It stated that on December 19th, 1798, at eight o’clock in the evening, a large, luminous meteor was seen at Benares and other parts of the country. It was attended with a loud, rumbling noise, like an ill-discharged platoon of musketry; and about the same time, the inhabitants of Krakhut, fourteen miles from Benares, saw the light, heard an explosion, and immediately after the noise of heavy bodies falling in the neighborhood. The sky had previously been serene, and not the smallest vestige of a cloud had appeared for many days. Next morning, the mould in the fields was found to have been turned up in many spots; and unusual stones, of various sizes, but of the same substance, were picked out from the moist soil, generally from a depth of six inches. As the occurrence took place in the night, after the people had retired to rest, the explosion and the actual fall of the stones were not observed; but the watchman of an English gentleman, near Krakhut, brought him a stone the next morning, which had fallen through the top of his hut, and buried itself in the earthen floor. This event in India was followed, in the year 1803, by a convincing demonstration in France, which compelled the eminent men of the capital to believe, though much against their will. On Tuesday, April 26th, about one in the afternoon, the weather being serene, there was observed in a part of Normandy, including Caen, Falaise, Alençon, and a large number of villages, a fiery globe of great brilliancy moving in the atmosphere with great rapidity. Some moments after, there was heard in L’Aigle and in the environs, to the extent of more than thirty leagues in every direction, a violent explosion, which lasted five or six minutes. At first there were three or four reports, like those of a cannon, followed by a kind of discharge which resembled the firing of musketry; after which there was heard a rumbling like the beating of a drum. The air was calm, and the sky serene, except a few clouds, such as are frequently observed. The noise proceeded from a small cloud which had a rectangular form, and appeared motionless all the time that the phenomenon lasted. The vapor of which it was composed was projected in all directions at the successive explosions. The cloud seemed about half a league to the northeast of the town of L’Aigle, and must have been at a great elevation in the atmosphere, for the inhabitants of two hamlets, a league distant from each other, saw it at the same time above their heads. In the whole canton over which it hovered, a hissing noise like that of a stone discharged from a sling was heard, and a multitude of mineral masses were seen to fall to the ground. The largest that fell weighed 17-1/2 pounds; and the gross number amounted to nearly three thousand. By the direction of the Academy of Sciences, all the circumstances of this event were minutely examined by a commission of inquiry, with the celebrated M. Biot at its head. They were found in harmony with the preceding relation, and reported to the French minister of the interior. Upon analyzing the stones, they were found identical with those of Benares.

The following are the principal facts with reference to the aërolites, upon which general dependence may be placed. Immediately after their descent they are always intensely hot. They are covered with a fused black incrustation, consisting chiefly of oxide of iron; and, what is most remarkable, their chemical analysis develops the same substances in nearly the same proportions, though one may have reached the earth in India and another in England. Their specific gravities are about the same; considering 1000 as the proportionate number for the specific gravity of water, that of some of the aërolites has been found to be,

Gassendi’s3456

Yorkshire3508

Bachelay’s3535

Bohemia4281

The greater specific gravity of the Bohemian stone arose from its containing a greater proportion of iron. An analysis of one of the stones that fell at L’Aigle gives:

Silica46 per cent

Magnesia10 ”

Iron45 ”

Nickel 2 ”

Sulphur 5 ”

Zinc 1 ”

Iron is found in all these bodies, and in a considerable quantity, with the rare metal nickel. It is a singular fact, that though a chemical examination of their composition has not discovered any substance with which we were not previously acquainted, yet no other bodies have yet been found, native to the earth, which contain the same ingredients combined. Neither products of the volcanoes, whether extinct or in action, nor the stratified or unstratified rocks, have exhibited a sample of that combination of metallic and earthy substances which the meteoric stones present. During the era that science has admitted their path to the earth as a physical truth, scarcely amounting to half a century, few years have elapsed without a known instance of descent occurring in some region of the globe. To Izarn’s list, previously given, upward of seventy cases might be added, which have transpired during the last forty years. A report relating to one of the most recent, which fell in a valley near the Cape of Good Hope, with the affidavits of the witnesses, was communicated to the Royal Society, by Sir John Herschel, in March, 1840. Previously to the descent of the aërolites, the usual sound of explosion was heard, and some of the fragments falling upon grass, caused it instantly to smoke, and were too hot to admit of being touched. When, however, we consider the wide range of the ocean, and the vast unoccupied regions of the globe, its mountains, deserts, and forests, we can hardly fail to admit that the observed cases of descent must form but a small proportion of the actual number; and obviously in countries upon which the human race are thickly planted many may escape notice through descending in the night, and will lie imbedded in the soil till some accidental circumstance exposes their existence. Some, too, are no doubt completely fused and dissipated in the atmosphere, while others move by us horizontally, as brilliant lights, and pass into the depths of space. The volume of some of these passing bodies is very great. One which traveled within twenty-five miles of the surface, and cast down a fragment, was suppose to weigh upward of half a million of tons. But for its great velocity, the whole mass would have been precipitated to the earth. Two aërolites fell at Braunau, in Bohemia, July 14, 1847.

In addition to aërolites, properly so called, or bodies known to have come to us from outlying space, large metallic masses exist in various parts of the world, lying in insulated situations, far remote from the abodes of civilization, whose chemical composition is closely analogous to that of the substances the descent of which has been witnessed. These circumstances leave no doubt as to their common origin. Pallas discovered an immense mass of malleable iron, mixed with nickel, at a considerable elevation on a mountain of slate in Siberia, a site plainly irreconcilable with the supposition of art having been there with its forges, even had it possessed the character of the common iron. In one of the rooms of the British Museum there is a specimen of a large mass which was found, and still remains, on the plain of Otumba, in the district of Buenos Ayres. The specimen alone weighs 1400 lbs., and the weight of the whole mass, which lies half buried in the ground, is computed to be thirteen tons. In the province of Bahia, in Brazil, another block has been discovered weighing upward of six tons. Considering the situation of these masses, with the details of their chemical analysis, the presumption is clearly warranted that they owe their origin to the same causes that have formed and projected the aërolites to the surface. With reference to the Siberian iron a general tradition prevails among the Tartars that it formerly descended from the heavens. A curious extract, translated from the Emperor Tchangire’s memoirs of his own reign is given in a paper communicated to the Royal Society, which speaks of the fall of a metallic mass in India. The prince relates, that in the year 1620 (of our era) a violent explosion was heard at a village in the Punjaub, and at the same time a luminous body fell through the air on the earth. The officer of the district immediately repaired to the spot where it was said the body fell, and having found the place to be still hot, he caused it to be dug. He found that the heat kept increasing till they reached a lump of iron violently hot. This was afterward sent to court, where the emperor had it weighed in his presence, and ordered it to be forged into a sabre, a knife, and a dagger. After a trial the workmen reported that it was not malleable, but shivered under the hammer; and it required to be mixed with one third part of common iron, after which the mass was found to make excellent blades. The royal historian adds, that on the incident of this iron of lightning being manufactured, a poet presented him with a distich that, “during his reign the earth attained order and regularity; that raw iron fell from lightning, which was, by his world-subduing authority, converted into a dagger, a knife, and two sabres.”
