which I am acquainted. Still I cannot pronounce them identical, though my very imperfect examination had enabled me to indicate silicon from the first, as a constituent of the Randolph specimen. They were each found under circumstances equally favorable as in the case of the Rutherford iron, to the idea of their being natural productions. But unfortunately, the size of the specimens was so small as to render their full elucidation difficult. Nevertheless, I hope very soon to subject them anew to examination; and I think I may add, with every probability of establishing the real existence of the group of meteoric irons originally proposed, but which has temporarily been withdrawn from my classification.

As a convenient name for the Rutherfordton species of matter, I would propose that of Ferrosilicine.

ART. XXXIII.-On a Shooting Meteor, seen to fall at Charleston, South Carolina, on the evening of November 16th, 1857, with notices of other supposed shooting meteors; by CHARLES UPHAM SHEPARD.

IN calling attention to the matter of a shooting meteor, I am conscious, that the evidence of its genuineness is not absolutely perfect; nevertheless, it falls so little short of entire satisfactoriness, as to make it fully worthy of notice. No instance of the kind at least, has yet been recorded, entitled to so much confidence. In detailing the circumstances, I shall aim to present every particular, precisely as it came to my knowledge.

Mr. Sparkman R. Scriven, aged about 17, and clerk in the dry goods store of Messrs. Browning & Ketchum of King street, Charleston, a young man of excellent character, was the principal observer of the phenomenon. He had just returned, at half past 8 in the evening of Nov. 16th, 1857, to the residence of his father (Mr. J. M. Scriven) in Morris street, three doors west of King, and having occasion to step into the portico, he saw a red, fiery ball of the size and shape of an orange, slowly descending through a distance apparently of 20 or 30 feet, to the ground. Its fall was scarcely more rapid than that of a soap bubble, giv ing him time to call his sister, a little girl, to see it strike a high wooden fence, distant about fifty or sixty feet from the portico, and which separated the door-yard from a church enclosure adjoining. It seemed to adhere for an instant to the board against which it struck, and then separated into three parts and disappeared. The evening was dark, it having followed a rainy afternoon, though at the time of the fall, it had ceased to rain and become very foggy.

Nothing further would probably have been heard of the phenomenon but for the accidental reading, by an elder sister the next day at the breakfast table, of a paragraph from the newspaper, relating to a meteoric fall, where the specimens picked up were said to have possessed a strong odor of sulphur. This induced young Scriven, who had never before heard of meteoric falls, at once to examine the fence against which the ball had struck. The fence was eight feet high, and formed of long strips of horizontally disposed boards. It was near the extremity of an uppermost board, that had been detached and bent around so as to present its flat side uppermost, that the body had been seen to impinge. And here it was, that he discovered adhering, a small bristling mass of black fibres. These he detached and carried into the house. As it had rained again during the night, he was led to suppose that the rest of the matter had been washed away. He searched the ground among the dead grass, but not until after the second night, when much more rain had fallen. He could find no more of the same material, though he gathered up numerous small fragments, which proved to be ordinary charcoal.

Mr. Scriven (the father) was so much struck with the appearance of the black fibres, together with the circumstances under which they had been found, that he requested his son to call on Dr. Wm. Pettigrew, the family physician, and describe to him what had happened. Two days however elapsed, before Dr. Pettigrew heard of the case. He immediately repaired to the house, where he was informed of the particulars as above described, and shown a mere pinch of the matter that had been detached from the fence,-the principal portion of it having unfortunately been given to a young man of the neighborhood, an engineer at the depot of the Northwestern railroad, who wished to exhibit it to his friends.

Dr. Pettigrew immediately called to acquaint me of the case; but not finding me at home, we did not meet until the forenoon of the 20th, when he presented me the specimen gathered by Scriven, and took me to the spot.

I heard the statements repeated from the different members of the family, corroborative of those above presented, and examined the place upon the board, from whence the fibres had been gath ered. It presented no discoloration or appearance of having been heated or charred, though for many inches on either side, it was slightly blackened in spots. This perhaps was not strange, as heavy rains had fallen since the occurrence; and it might fairly be presumed, that all foreign matter would have been effectually detached. I examined the grass and soil on both sides of the fence, without finding anything beyond little fragments of charcoal, which are common enough in most places about the

premises of houses. We then took pains to find the individual to whom had been given the principal portion of the fibrous matter obtained from the fence; but had the mortification to discover, that having worn it in a paper wrapper for several days in his vest pocket, he had finally mislaid or lost it. Thus little more than a microscopically visible specimen of the shooting star remained for study and examination. Its entire weight is probably less than one-tenth of a grain. When viewed by a single pocketlens, it seems to be a confused aggregate of short clippings of the finest black hair, varying in length from one-tenth to onethird of an inch. Each portion is straight or only slightly curved. Except in color, they remind one most of that variety of pumice stone from the Sandwich Islands, known as volcanic hair, or as "Pele's hair." They do not seem very prone to break in handling, and appear slightly elastic.

They have been examined under compound microscopes of high power by several persons accustomed to the use of this instrument; but hitherto no one has ventured to suggest a relationship in their properties, to any known form of organic or inorganic matter. The following description is from a note, handed to me by my friend, Dr. F. W. Porcher of Charleston. "Black elongated bodies, perfectly opaque, round and solid; amorphous, not properly smooth, surfaces often furnished with warty dots or projections; rather glossy."

In fig. 1, I have enlarged Dr. Porcher's drawings of a few of the forms about four times, as they presented themselves to him, through a one-third inch object-glass. A few of the bodies are subspinose, and one or two decidedly bifurcate; others are cancellated, and seem capable of separation into smaller fibres. The surfaces are not always perfectly round.

I could spare only a few of them for a chemical trial. These were introduced into a small glass test-tube (previously we'l dried), and heated by contact of the flame of the blowpipe. They suddenly glowed with a brilliant light, at the same time emitting an odor most nearly resembling the bituminous. A distinct greyish skeleton of each fibre was left adhering to the glass. Barytic water being thrown into the tube was instantly rendered milky, thereby proving the existence of carbonic acid; and the subsequent addition of hydrochloric acid slowly caused the separation of the skeletons from the glass, which led me to infer the presence of silica as a part of the earthy residuum. The little bodies however were not annihilated by the process; but greatly to my surprise were easily seen, by the aid of a single lens, still floating through the clear liquid, preserving in a great measure their original form, with the exception only, of being rendered here and there transparent, as if about one-half of the black

matter had been caten out and dissolved, leaving the remainder sufficiently connected to maintain the original figure of the body. This honeycomb appearance is also represented in three of the drawings (fig. 2) made by Dr. Porcher.

This is all that I have been able to ascertain concerning the origin, structure, and chemical composition of these singular bodies. They appear to be inorganic, though composed in part of carbon. A large proportion of earthy matter also, enters into their composition.

It will be remembered perhaps, in this connexion, that Berzelius detected what appeared to him to be an organic residuum (resembling burnt hay) in the French meteoric stone of Alais that fell March 15, 1806; and bearing more distinctly still upon our subject, are the highly interesting results recently obtained by Prof. Wöhler on the unknown substance of an or ganic nature (resinous) in the meteoric stone of Kaba, Hungary, that fell April 15, 1857, and those again arrived at by Prof. E. P. Harris in the Göttingen laboratory concerning the carbonaceous matter in the stone that fell Oct. 13, 1838, at Cape of Good Hope, a meteorite originally described by Sir John Herschell and Prof. Faraday. Prof. Harris states in his valuable thesis on meteorites (Göttingen, 1859), that he

finds a quarter per cent of bituminous matter in the Cape stone, which is soluble both in alcohol and ether, and fusible in a glass tube over a spirit lamp. It finally burns with a bituminous odor and the deposition of carbon.

SECOND SERIES, VOL. XXVIII, No. 83,-SEPT., 1859.

Is the matter of the Charleston shooting-star analogous to that of the Alais and the Cape meteoric stones? And if so, may the more complete combustion of its carbonaceous ingredient have been prevented by the humid state of the atmosphere at the time of its fall? These are questions that naturally suggest themselves, but to which we are not in a condition to return satisfactory replies at present.*

It is reasonable perhaps to suppose that many aggregates of me. teoric matter, such for example as those made up wholly of one or more of the following meteoric elements; carbon, phosphorus and sulphur would, owing to their easy combustibility burn out, even in the upper regions of the atmosphere, and being resolved into gaseous compounds, fail of transmitting to the earth's surface any material proof of their existence, Others again may not be recognized at the surface of the earth, owing to the dispersion of their oxyds in the condition of an impalpable dust, or in solution in water. But however this may be, the facts seem thickening about us of the occasional arrival out of the air, of anomalous earthy bodies, whose descent is unaccompanied by the explosions belonging to the true meteorites, and the precipitated matter is uncharacterized also, by the possession of a thin, well fused coating or crust.

The study of these pseudo or doubtful meteorites, as they have been called, is worthy of a much closer attention than has hitherto been devoted to them; and it is to be regretted, that they continue still to be treated much as the true stones and iron masses were, prior to the time of Chaldni and Howard. Their study seems to be regarded as a field, exterior to the domain of legitimate science, a region for the reception of all that is vague and contradictory. Much time and labor will no doubt be requisite to disentangle what is really entitled to scientific regard; but this desirable result will be yet longer postponed, if naturalists continue to dismiss as unworthy of investigation, every reported meteoric fall that is unattended with the stereotyped accompaniments, of the descent of the black encrusted stone and iron-mass, the frequency of whose arrival has now so multiplied, as to make the recital of their apparition almost monotonous.

Without here referring to many of the doubtful meteorites, of which I have from time to time given notices, I will venture to call attention to a few other instances, of which no scientific mention has yet been made,-not claiming for them however,

* As having possibly a close connexion with the subject in hand, may be mentioned, two instances recorded in Chladni's list of ancient meteorites. The first of these refers to the fall at Rockhausen near Erfort, July 5, 1582, during a frightful tempest, of a large quantity of a fibrous substance, similar to hair. The second occurred March 23, 1665 at a place near Lancha, not far from Naumburg, in which case, the matter that fell was likewise fibrous, and resembled a bluish silk. It was also abundant.
