From The Position Of The Mountains And Thick Forests Which Surround The Missions Of The Cataracts And The Little Village Of Maroa, I Presume That The Bolides Were Still Visible At 20 Degrees Above The Horizon.

On my arrival at the southern extremity of Spanish Guiana, at the little fort of San Carlos, I found some Portuguese, who had gone up the Rio Negro from the Mission of St. Joseph of the Maravitans.

They assured me that in that part of Brazil the phenomenon had been perceived at least as far as San Gabriel das Cachoeiras, consequently as far as the equator itself.* (* A little to the north-west of San Antonio de Castanheiro. I did not meet with any persons who had observed this meteor, at Santa Fe de Bogota, at Popayan, or in the southern hemisphere, at Quito and Peru. Perhaps the state of the atmosphere, so changeable in these western regions, prevented observation.)

I was forcibly struck by the immense height which these bolides must have attained, to have rendered them visible simultaneously at Cumana, and on the frontiers of Brazil, in a line of two hundred and thirty leagues in length. But what was my astonishment, when, on my return to Europe, I learned that the same phenomenon had been perceived on an extent of the globe of 64 degrees of latitude, and 91 degrees of longitude; at the equator, in South America, at Labrador, and in Germany! I saw accidentally, during my passage from Philadelphia to Bordeaux,* (* In the Memoirs of the Pennsylvanian Society.) the corresponding observation of Mr. Ellicot (latitude 30 degrees 42); and upon my return from Naples to Berlin, I read the account of the Moravian missionaries among the Esquimaux, in the Bibliothek of Gottingen.

The following is a succinct enumeration of the facts:

First. The fiery meteors were seen in the east, and the east-north-east, at 40 degrees of elevation, from 2 to 6 a.m. at Cumana (latitude 10 degrees 27 minutes 52 seconds, longitude 66 degrees 30 minutes); at Porto Cabello (latitude 10 degrees 6 minutes 52 seconds, longitude 67 degrees 5 minutes); and on the frontiers of Brazil, near the equator, in longitude 70 degrees west of the meridian of Paris.

Second. In French Guiana (latitude 4 degrees 56 minutes, longitude 54 degrees 35 minutes) "the northern part of the sky was suffused with fire. Numberless falling-stars traversed the heavens during the space of an hour and a half, and shed so vivid a light, that those meteors might be compared to the blazing sheaves which shoot out from fireworks." The knowledge of this fact rests upon the highly trustworthy testimony of the Count de Marbois, then living in exile at Cayenne, a victim to his love of justice and of rational, constitutional liberty.

Third. Mr. Ellicot, astronomer to the United States, having completed his trigonometric operations for the rectification of the limits on the Ohio, being on the 12th of November in the gulf of Florida, in latitude 25 degrees, and longitude 81 degrees 50 minutes, saw in all parts of the sky, "as many meteors as stars, moving in all directions.
