borhood of our sun, and within the sphere of our observation, in 1835. As that time approached, the computation of its orbit was made with great care and labor by a number of very eminent mathematicians, and every perturbing force that might affect it was taken into account. The result established the triumph of science, and showed how firmly and successfully the human intellect has grappled with the great problem of the path of comets in space. Rosenberger fixed on the 11th of November, 1835, as the time of its perihelion; and the comet having been first seen at Rome on the 6th of August, advanced rapidly towards the sun, and made its perihelion passage on the 15th of November, only four days after the calculated time. This was indeed wonderful accuracy, in tracing the path and computing the period of a body that recedes into space the amazing distance of 3,370,300,000 miles, which in that long journey passes within the range of so many perturbing forces, and which travels at degrees of speed so gradually and so greatly varying. It bears magnificent testimony to the power and grasp of the intellect of man. Yet, let none be proud because of what they have received. The thought that the unknown is vastly, boundlessly more than the known, should keep the wisest, and most learned, and most vigorous-minded, humble. And let the noble achievements of human intellect testify to man, that he is made for something better than grovelling among the sensualities of the world; for something better even than the study of the material forms of the universe, and the laws by which they are governed; that he will find his highest and ultimate occupation in the knowledge of the Creator and Lawgiver himself, and his highest and only happiness in the enjoyment of that Creator and Lawgiver as the God of grace and redemption--a covenant God in Jesus Christ-the Saviour and portion of the immortal spirit.

Astronomers, put into the right tract by the computations and prediction of Halley, and by the verification of that prediction, were not long in pointing out other comets with a periodic time. In 1819, Professor Encke, of Berlin, detected the periodicity of the comet which now goes by his name, and showed that it had a period of about three years and a-quarter. Many opportunities, owing to the short period of this comet, have been afforded for varied and accurate observation, and for calculating its elements with the nicest care. Encke himself bestowed amazing labor on the investigation, and he

was led to the astounding and singular conclusion, that the orbit of the comet is gradually diminishing, and that ere long it must fall into the sun. Encke's comet presents the appearance of a round nebulous body, with a bright nuclear condensation, and it is destitute of a tail. It can be seen, when most favorably situated, by the naked eye, as a star of the fifth or sixth magnitude.

In 1826, the periodicity of the fine comet called Biela's comet was discovered. This comet presents the appearance of a small round nebulous body, with a feeble condensation towards the centre, and without any tail. Its periodical time has been ascertained to be about 6 years, or more accurately 6.617 years. We find in Mr. Hind's work on Comets an interesting account of a very remarkable change observed to take place in this comet during its visit to the region of our system, in the end of 1848 and beginning of 1849. That change consisted in an actual separation into two distinct nebulosities, which travelled in company for more than three months. The apparent distance between them was, at first, little more than two minutes, but subsequently it increased to about fourteen minutes. We can not even mention the other comets whose periodicity has been recently detected. In some it ranges from five to eight years; in others, if we may credit the calculations, it ranges from 3,000 to upwards of 100,000 years!

In connection with these ascertained periodic times, and these bewildering periods and distances, the question suggests itself, Do all comets move in an elliptical orbitfrom some far turning-point in space directing their course towards the sun with motion gradually accelerated, till, on their burning path, they rush past and round him, and recede away a journey of many, many years, to the immensely distant point whence they must begin again their journey towards him? -or do these travellers in space pass away into the depths of the universe till they come within the sphere of the attraction of some other sun as glorious and powerful, or more so, than ours, round which they sweep with lightning speed, and fly off to seek yet another, and from that other yet another, of the great central suns of God's stupendous universe, forming thus a connecting link between the systems of which that universe is composed?

Comets may have their motion accelerated or retarded, and even their orbits changed, by coming within the influence of the

Mr. Müller, master of each moment protested against the immothis establishment, did its honors with bility of her bearing, auburn hair whose rich thorough German gravity. Perfect order, and silken curls admirably harmonized with extreme and conscientious cleanliness, reigned the serenity of her features, a graceful and throughout the house. One might pass flexible form just expanding into womanhood; through the servants' room, and even through such was Ellen Müller. the kitchens, without meeting with any thing by which the sight was in the least offended. The cellar was as well arranged as a book case, and the regulations of the house, as regarded both the service and the hours of meals, were as punctually observed as they could have been in a seminary. If a guest came in late, though it were but ten minutes, he was served apart, in an adjoining room, that the comfort of all might not be sacri-losophy, politics, or literature, were the usual ficed to the convenience of one.

A councillor of the Court, Hofrath Baron von Noth, who had resigned his functions in consequence of an injustice that had been done him, several students, whose parents had recommended them to the vigilance of Mr. Müller, and a few merchants, composed the majority of the habitual guests. The party was frequently increased by travellers, literary men, and artists. After dinner, phi

topics of conversation, in which Mr. Müller, a man of extensive acquirements and great good sense, took part, with a choice of expressions and an elevation of views that would have astonished me in a man of his station in any country but Germany.

Sometimes Ellen would sit down to the piano, and sing some of those simple and beautiful melodies in which the tenderness, the gravity, and the piety of the German national character seem to mingle. Then conversation ceased; every countenance expressed profound attention; and each listener, as if he were assisting at a religious service, translated the accents of that universal language according to his sympathies, his associations, and the habitual direction of his ideas.

In the conversation at this table-d'hôte there prevailed a tone of good society which excluded neither ease nor pleasantry; but a caustic or indelicate expression would have jarred on the ear like a false note in a wellexecuted concert. The countenance of Mrs. Müller, in which dignity was blended with benevolence, was the barometer by which the young men regulated themselves when the influence of Rhine wine or Stettin beer might lead them a little too far. Then Mrs. Müller assumed an air of reserve; by a few words she adroitly broke off the conversation, and turned it into another channel; and she glanced gravely at her daughter, who, with out affectation or pouting, kept her eyes fixed on her plate until the end of the meal.

Ellen Müller was the type of those beautiful German faces which the French call cold, because they know not how to read them; she was a happy mixture of the Saxon and Hanoverian characters. A pure and open

I was not long in perceiving that Baron von Noth and a young student named Werter were particularly sensible to Ellen's charms and merit. In the baron, a middle-aged man, there was a mixture of dignity and eagerness

which betrayed an almost constant struggle between pride and the energy of a strong passion. It is between the ages of thirty and forty that the passions have most empire over us. At that period of life the character is completely formed; and as we well know what we desire, so do we strive to attain our end with all the energy of a perfect organization.

Werter was little more than nineteen years old. He was tall, fair, and melancholy. I am persuaded that love had revealed itself to the young student by the intermediation of the musical sense. I had more than once watched him when Ellen sang. A sort of fever agitated him; he isolated himself in a corner of the room, and there, in a mute ecstacy, the poor boy inhaled the poison of love.

The pretensions of Ellen's two admirers manifested themselves by attentions of very different kinds, and in which were displayed their different natures. The baron brought

Mrs. Müller tickets for concerts and theatres. Often at the dessert, he would send for delicious Hungarian wine, in which he drank the health of the ladies, slightly inclining his head to Ellen, as if he would have said-I bow to you alone. Werter would stealthily place upon the piano a new ballad, or a volume of poetry; and when the young girl took it up, his face flushed and brightened as if the blood were about to burst from it. Ellen smiled modestly at the baron, or gracefully thanked the student; but she seemed not to suspect that which neither of them dared to tell her.

One night, that we were assembled in the drawing-room, one of the habitual visitors to the house presented to us a Jew, who had just arrived from Lemberg, and whom business was to detain for some months at Vienna. In a few words, Mr. Müller made the stranger acquainted with the rules and the customs of the house. The Jew replied by monosyllables, as if he disdained to expend more words and intelligence upon details so entirely material. He bowed politely to the ladies, glanced smilingly at the furniture of the room, round which he twice walked, as if in token of taking possession, and then installed himself in an arm-chair. This pantomime might have been translated thus: "Here I am; look at me once for all, and then heed me no more." Mr. Malthus-that was the Jew's name-had a decided limp in his gait; he was a man of the middle height, and of a decent bearing; his hair was neglected; but a phrenologist would have read a world of things in the magnificent development of his

An attentive observer of all that passed, I did my utmost to read Ellen's heart, and to decide as to the future chances of the baron's or the student's love. She was passionately fond of narratives of adventure, and, thanks to the wandering life I had led, I was able to gratify this taste. I noticed that traits of generosity and noble devotion produced an extraordinary effect upon her. Her eyes sparkled as though she would fain have distinguished, through time and space, the hero of a noble action; then tears moistened her beautiful lashes, as reflection recalled her to the realities of life. I understood that neither the baron nor Werter was the man to win her heart; they were neither of them equal to her. Had I been ten years younger, I think I should have been vain enough to enter the lists. But another person, whom none would at first have taken for a man capable of feeling and inspiring a strong passion, was destined to carry off the prize.

forehead.

The conversation became general. Mr. Malthus spoke little, but as soon as he opened his mouth everybody was silent. This apparent deference proceeded perhaps as much from a desire to discover his weak points as from politeness towards the new-comer.

The Jew had one of those penetrating and sonorous voices whose tones seem to reach the very soul, and which impart to words inflexions not less varied than the forms of thought. He summed up the discussion logically and lucidly; but it was easy to see that, out of consideration for his interlocutors, he abstained from putting forth his whole strength.

The conversation was intentionally led to religious prejudices: at the first words spoken on this subject, the Jew's countenance assumed a sublime expression. He rose at once to the most elevated considerations: it was easy to see that his imagination found itself in a familiar sphere. He wound up with so pathetic and powerful a peroration, that Ellen, yielding to a sympathetic impulse, made an abrupt movement towards him. Their two souls had met, and were destined mutually to complete each other.

I said to myself, that Jew will be Ellen's husband.

Then I applied myself to observe him more attentively. When Mr. Malthus was not strongly moved and animated, he was but an ordinary man; nevertheless, by the expression of his eyes, which seemed to look within himself, one could discern that he was inter
