      On November 12th, 1837, at eight o’clock in the evening, the attention of observers in various parts of Great Britain was directed to a bright, luminous body, apparently proceeding from the north, which, after making a rapid descent, in the manner of a rocket, suddenly burst, and scattering its particles into various beautiful forms, vanished in the atmosphere. This was succeeded by others all similar to the first, both in shape and the manner of its ultimate disappearance. The whole display terminated at ten o’clock, when dark clouds which continued up to a late hour, overspread the earth, preventing any further observation. In the November of 1838, at the same date, the falling stars were abundant at Vienna: and one of remarkable brilliancy and size, as large as the full moon in the zenith, was seen on the 13th by M. Verusmor, off Cherburg, passing in the direction of Cape La Hogue, a long, luminous train marking its course through the sky. The same year, the non-commissioned officers in the island of Ceylon were instructed to look out for the falling stars. Only a few appeared at the usual time; but on the 5th of December, from nine o’clock till midnight, the shower was incessant, and the number defied all attempts at counting them.

      Professor Olmsted, an eminent man of science, himself an eye-witness of the great meteoric shower on the American continent, after carefully collecting and comparing facts, proposed the following theory: The meteors of November 13th, 1833, emanated from a nebulous body which was then pursuing its way along with the earth around the sun; that this body continues to revolve around the sun in an elliptical orbit, but little inclined to the plane of the ecliptic, and having its aphelion near the orbit of the earth; and finally, that the body has a period of nearly six months, and that its perihelion is a little within the orbit of Mercury. The diagram represents the ellipse supposed to be described, E being the orbit of the earth, M that of Mercury, and N that of the assumed nebula, its aphelion distance being about 95 millions of miles, and the perihelion 24 millions. Thus, when in aphelion, the body is close to the orbit of the earth, and this occurring periodically, when the earth is at the same time in that part of its orbit, nebulous particles are attracted toward it by its gravity, and then, entering the atmosphere, are consumed in it by their concurrent velocities, causing the appearance of a meteoric shower. The parent body is inferred to be nebular, because, though the meteors fall toward the earth with prodigious velocity, few, if any, appear to have reached the surface. They were stopped by the resistance of the air and dissipated in it, whereas, if they had possessed any considerable quantity of matter, the momentum would have been sufficient to have brought them down in some instances to the earth. Arago has suggested a similar theory, that of a stream or group of innumerable bodies, comparatively small, but of various dimensions, sweeping round the solar focus in an orbit which periodically cuts that of the earth. These two theories are in substance the Chladnian hypothesis, first started to explain the observed actual descent of aërolites. Though great obscurity rests upon the subject, the fact may be deemed certain that independently of the great planets and satellites of the system, there are vast numbers of bodies circling round the sun, both singly and in groups, and probably an extensive nebula, contact with which causes the phenomena of shooting stars, aërolites, and meteoric showers. But admitting the existence of such bodies to be placed beyond all doubt, the question of their origin, whether original accumulations of matter, old as the planetary orbs, or the dispersed trains of comets, or the remains of a ruined world, is a point beyond the power of the human understanding to reach.

      A FIVE DAYS’ TOUR IN THE ODENWALD

      The Odenwald, or Forest of Odin, is one of the most primitive districts of Germany. It consists of a hilly, rather than a mountainous district, of some forty miles in one direction, and thirty in another. The beautiful Neckar bounds it on the south; on the west it is terminated by the sudden descent of its hills into the great Rhine plain. This boundary is well known by the name of the Bergstrasse, or mountain road; which road, however, was at the foot of the mountains, and not over them, as the name would seem to imply. To English travelers, the beauty of this Bergstrasse is familiar. The hills, continually broken into by openings into romantic valleys, slope rapidly down to the plain, covered with picturesque vineyards; and at their feet lie antique villages, and the richly-cultivated plains of the Rhine, here thirty or forty miles wide. On almost every steep and projecting hill, or precipitous cliff, stands a ruined castle, each, as throughout Germany, with its wild history, its wilder traditions, and local associations of a hundred kinds. The railroad from Frankfort to Heidelberg now runs along the Bergstrasse, and will ever present to the eyes of travelers the charming aspect of these old legendary hills; till the enchanting valley of the Neckar, with Heidelberg reposing amid its lovely scenery at its mouth, terminates the Bergstrasse, and the hills which stretch onward, on the way toward Carlsruhe, assume another name.

      Every one ascending the Rhine from Mayence to Mannheim has been struck with the beauty of these Odenwald hills, and has stood watching that tall white tower on the summit of one of them, which, with windings of the river, seem now brought near, and then again thrown very far off; seemed to watch and haunt you, and, for many hours, to take short cuts to meet you, till, at length, like a giant disappointed of his prey, it glided away into the gray distance, and was lost in the clouds. This is the tower of Melibocus, above the village of Auerbach, to which we shall presently ascend, in order to take our first survey
