Here I intended to have concluded all my observations. But a recent publication, which I knew not of, when these sheets were written, obliges me to add a few more pages. In a very singular tract, published in 1794, at Riga, by Dr. _Chladni_, concerning the supposed origin of the mass of iron found by Dr. Pallas in Siberia; which the Tartars still affirm to be _an holy thing_, and, _to have fallen from heaven_; and concerning what have been supposed, by him, to be similar phaenomena; some circumstances are also mentioned, which it would be an unjust omission not to take notice of shortly, on the present occasion. With the author's hypothesis I do not presume to interfere; but surely his facts, which he affirms in support of his ideas, deserve much attention; and ought to be inserted, before I conclude these observations: and the rather, as they were adduced to maintain conclusions very different from these now offered to the consideration of the curious. On the 21st of May, 1676, a fire ball was seen to come from Dalmatia,[HH] proceeding over the Adriatic sea; it passed obliquely over Italy; where an hissing noise was heard; it burst SSW from Leghorn, with a terrible report; _and the pieces are said to have fallen into the sea_, with the same sort of noise, as when red hot iron is quenched or extinguished in water. Its height was computed to be not less than thirty-eight Italian miles; and it is said to have moved with immense velocity. Its form was oblong, at least as the luminous appearance seemed in its passage. _Avicenna_ mentions, (Averrhoes, lib. 2do Meteor. cap. 2.) that he had seen at Cordova, in Spain, a sulphureous stone that had fallen from heaven. In _Spangenberg_'s Chron. Saxon, an account is found, that at Magdeburg, in A. D. 998, two great stones, fell down in a storm of thunder: one in the town itself; the other near the Elbe, in the open country. The well known, and celebrated _Cardan_, in his book, _De Varietate Rerum_, lib. 14. cap. 72. tells us, that he himself, in the year 1510, had seen one hundred and twenty stones fall from heaven; among which one weighed one hundred and twenty; and another sixty pounds. That they were mostly of an _iron colour_, and very hard, and smelt of brimstone. He remarks, moreover, that about three o'clock, a great fire was to be seen in the heavens; and that about five o'clock the stones fell down with a rushing noise. And _Julius Scaliger_ (in his book _De Subtilitate Exerc._ p. 333.) affirms, that he had in his possession a piece of iron (as he calls it,) which had fallen from heaven in _Savoy_. _Wolf_ (in _Lection. Memorab._ Tom. II. p. 911.) mentions a great triangular stone, described by _Sebastian Brandt_, (which seems to have been the identical stone I have already mentioned as having been preserved in the church of Anxissem,) and which was said to have fallen from heaven, in the year 1493, at Ensisheim or Ensheim.
