AEROLITES.

These phenomena, otherwise entitled meteoric stones, have been

ascertained, by recent observations, to be connected with the bolides,

or fire-balls, described above. Scoriaceous masses have frequently been

either actually seen to fall at the time of the disappearance of the

latter, or have been found soon after on the surface of the earth. Most

of the stones which have fallen from the atmosphere, have been preceded

by the appearance of luminous bodies, or meteors. These meteors burst

with an explosion, and then the shower of stones falls to the earth.

Sometimes the stones continue luminous till they sink into the earth;

but most commonly their luminousness disappears at the time of their

explosion. These meteors move in a direction nearly horizontal, and seem

to approach the earth before they explode.

The stony bodies, when found immediately after their descent, are always

hot. They commonly bury themselves some depth under ground. Their size

differs, from fragments of a very inconsiderable weight, to masses of

several tuns. They usually approach the spherical form, and are always

covered with a black crust; in many cases they smell strongly of

sulphur. The black crust consists chiefly of oxyd of iron; and from

several accurate analyses of these stones, the following important

inferences have been drawn: that not any other bodies have as yet been

discovered on our globe which contain the same ingredients; and that

they have made us acquainted with a species of pyrites not formerly

known, nor anywhere else to be found.

The ancients were not unacquainted with these meteoric stones, a shower

of which is reported by Livy to have fallen at Rome under the consulate

of Tullus Hostilius, and another under that of C. Martius and M.

Torquatus. Pliny relates that a shower of iron (for thus he designates

these stones) fell in Lucania, a year before the defeat of Crassus, and

likewise speaks of a very large stone which fell near the river Negos,

in Thrace. In the chronicle of Count Marcellin, there is an account of

three immensely large stones having fallen in Thrace, in the year 452

before the advent of Christ.

To proceed to more modern and well authenticated instances of the fall

of aerolites. On the seventh of November, 1492, a little before noon, a

dreadful thunder-clap was heard at Ensisheim, in Alsace, instantly after

which a child saw a huge stone fall on a field newly sown with wheat. On

searching, it was found to have penetrated the earth about three feet,

and weighed two hundred and sixty pounds, making its size equal to a

cube of thirteen inches the side. All the contemporary writers agree in

the reality of this phenomenon, observing that, if such a stone had

before existed in a plowed land, it must have been known to the

proprietor. The celebrated astronomer Gassendi relates an instance of an

aerolite descent of which he was himself an eye-witness. On the

twenty-seventh of November, 1627, the sky being clear, he saw a burning

stone fall on Mont Vasir, in the south-east extremity of France, near

Nice. While in the air, it seemed to be about four feet in diameter, was

inclosed in a luminous circle of colors like a rainbow, and in its fall

produced a sound like the discharge of cannon. It weighed fifty-nine

pounds, was very hard, of a dull metallic color, and had a specific

gravity considerably greater than that of marble. In the year 1672, two

stones fell near Verona, in Italy, the one weighing three hundred, the

other two hundred pounds. This phenomenon was witnessed in the evening,

by three or four hundred persons. The stones fell, with a violent

explosion, in a sloping direction, and in calm weather. They appeared to

burn, and plowed up the ground. Paul Lucas, the traveler, relates that

when he was at Larissa, a town of Greece, near the gulf of Salonica, a

stone weighing seventy-two pounds, fell in the vicinity. It was observed

to come from the northward, with a loud hissing noise, and seemed to be

enveloped in a small cloud, which exploded when the stone fell. It

looked like iron dross, and smelt of sulphur. In September, 1753,

several stones fell in the province of Bresse, to the west of Geneva:

one in particular fell at Pont de Vesle, and another at Liponas, places

nine miles distant from each other. The sky was clear, and the weather

warm. A loud noise, and a hissing sound, were heard at those two places,

and for several miles round, on the fall of these stones, which exactly

resembled each other, were of a darkish, dull color, very ponderous, and

manifesting on their surface that they had suffered a violent degree of

heat. The largest weighed about twenty pounds, and penetrated about six

inches into the plowed ground; a circumstance which renders it highly

improbable that they could have existed there before the explosion. This

phenomenon has been described by the astronomer Delalande, whose strict

inquiries on the spot enabled him to testify the truth of the

circumstances he relates. In the year 1768, three stones were presented

to the French Academy of Sciences, which had fallen in different parts

of France; one at Luce, in the Maine; another at Aire, in Artois; and

the third in Cotentin. They were all externally of the same identical

appearance; and on the former of them a particular report was drawn up

by Messrs. Fougeraux, Cadet and Lavoisier. This report states, that on

the eighteenth of September, 1768, between four and five in the

afternoon, there was seen, near the above village of Luce, a cloud in

which a short explosion took place, followed by a hissing noise, but

without any flame. The same sound was heard by several persons about ten

miles from Luce; and, on looking up, they perceived an opaque body

describe a curve in the air, and fall on a piece of green turf near the

high road. They immediately ran to the spot, where they found a kind of

stone, half-buried in the earth, extremely hot, and weighing about seven

pounds and a half.

In the particular instance now to be cited, very distinct traces were

left to show the progress of aerolites through the air. During the

explosion of a meteor near Bordeaux, on the twentieth of August, 1789, a

stone, in diameter about fifteen inches, fell through the roof of a

cottage, and killed a herdsman and some cattle. Part of this stone is

now in the Greville museum, and part in the museum of Bordeaux. On the

twenty-fourth of July, 1790, between nine and ten at night, a shower of

stones fell near Agen, in Guienne, near the south-west angle of France.

First a luminous ball of fire was seen traversing the atmosphere with

great rapidity, and leaving behind it a train of light which lasted

about fifty seconds; soon after this a loud explosion was heard, and

sparks were seen to fly off in all directions. This was soon after

followed by the fall of stones, over a considerable extent of ground,

and at various distances from each other. These were all alike in

appearance, but of many different sizes, the greater number weighing

about two ounces, but many a vast deal more. Some fell with a hissing

noise, and entered the ground; but the smaller ones remained on the

surface. The only damage done by this shower of stones was, that they

broke the tiles of several houses, in falling on which they had not the

sound of hard and compact substances, but of matter in a soft,

half-melted state. Such as fell on straws adhered to them, and could not

be readily separated; a manifest proof that they were in a state of

fusion.

On the eighteenth of December, 1795, several persons near the house of

Captain Topham, in Yorkshire, heard a loud noise in the air, followed by

a hissing sound, and soon after felt a shock, as if a heavy body had

fallen to the ground at a little distance from them. In reality, one of

them saw a huge stone fall to the earth, at the distance of eight or

nine yards from the place where he stood. When he first observed it, it

was seven or eight yards above the ground; and in its fall it threw up

the mold on every side, burying itself twenty-one inches in the earth.

This stone on being dug up, was found to weigh fifty-six pounds. On the

seventeenth of March, 1798, a body, burning with an intense light,

passed over the vicinity of Ville Franche, on the Saone, near Lyons,

accompanied by a hissing sound, and leaving behind a luminous track.

This phenomenon exploded with a great noise, about twelve hundred feet

from the ground, and one of the splinters, still luminous, having been

observed to fall in a neighboring vineyard, was traced. It was about a

foot in diameter, and had penetrated twenty inches into the ground. On

the fourth of July, 1803, a ball of fire struck a public house at East

Norton, in Oxfordshire. The chimney was thrown down, the roof partly

torn off, the windows shattered to atoms, and the dairy, &c., converted

into a heap of rubbish. It was of considerable magnitude, and, on coming

in contact with the house, exploded with great noise, and a very

oppressive sulphureous smell. Several fragments of stones were found on

the spot, having a surface of a dark color, and varnished, as if in a

state of fusion, with numerous globules of a whitish metal, combining

sulphur and nickel. The indentures on these surfaces render it probable

that the ball was soft when it descended; and it was obviously in a

state of fusion, as the grass was burned where the fragments fell. The

motion of the fire-ball, while in the air, was very rapid, and

apparently parallel to the horizon.

The latest remarkable fall of aerolites in Europe, of which there is a

distinct account, was in the vicinity of Laigle, in Normandy, early in

the afternoon of the twenty-sixth of April, 1812. A fiery globe of a

very brilliant splendor, which moved in the air with great rapidity, was

followed in a few seconds by a violent explosion, which lasted five or

six minutes, and was heard to the extent of more than thirty leagues in

every direction. Three or four reports, like those of a cannon, were

followed by a discharge resembling a fire of musketry, after which a

dreadful rumbling was heard like the beating of a drum. The air was

calm, and the sky serene, with the exception of a few clouds, such as

are frequently observed. The noise proceeded from a small cloud of a

rectangular form, the largest side being in a direction from east to

west. It appeared motionless all the time the phenomenon lasted; but the

vapor of which it was composed was projected momentarily from the

different sides by the effect of the successive explosions. This cloud

was about half a league to the north-north-east of the town of Laigle,

and was at so great an elevation, that the inhabitants of two hamlets, a

league distant from each other, saw it at the same time over their

heads. In the whole canton over which this cloud hovered, a hissing

noise, like that of a stone discharged from a sling, was heard; and a

multitude of meteoric stones were seen to fall at the same time. The

district in which they fell forms an elliptical extent of about two

leagues and a half in length, and nearly one in breadth; the greatest

dimension being in a direction from south-east to north-west, forming a

declination of about twenty-two degrees. This direction, which the

meteor must have followed, is exactly that of the magnetic meridian;

which is a remarkable fact. The number of these stones was reckoned to

exceed three thousand; and the largest of them weighed nearly twenty

pounds. They were friable some days after their fall, and smelt strongly

of sulphur. They subsequently acquired the degree of hardness common to

this kind of stones.

While, in Europe, these phenomena thus strongly confirmed the long

exploded idea of the vulgar, that many of the luminous meteors observed

in the atmosphere, are masses of ignited matter, an account of one of

precisely the same description was received from the East Indies. On the

nineteenth of December, 1798, at eight in the evening, a large

fire-ball, or luminous meteor, was seen at Benares, and at several

places in its vicinity. It was attended by a loud rumbling noise; and,

about the same time, the inhabitants of Krakhut, fourteen miles from

Benares, saw the light, heard what resembled a loud thunder-clap, and,

immediately after, the noise of heavy bodies falling around them. Next

morning the mold in the fields was found to have been turned up in many

spots; and unusual stones of various sizes, but of the same substances,

were picked from the moist soil, generally at a depth of six inches. One

stone fell through the roof of a hut, and buried itself in the earthen

floor.

From these multiplied evidences it is proved that, in various parts of

the world, luminous meteors have been seen moving through the air with

surprising rapidity, in a direction more or less oblique, accompanied

with a noise, commonly like the whizzing of cannon-balls, followed by

explosion, and the fall of hard, stony, or semi-metallic masses in a

heated state. The constant whizzing sound; the fact of stones being

found, like each other, but unlike all others in the vicinity, at the

spots toward which the luminous body, or its fragments, had been seen to

move; the scattering or plowing up of the soil at those spots, always in

proportion to the size of the stones; the concussion of the neighboring

ground at the same time; and especially, the impinging of the stones on

bodies somewhat above the earth, or lying loose on its surface; all

these are circumstances perfectly well authenticated in these reports,

proving that such meteors are usually inflamed hard masses, descending

rapidly through the air to the earth.
