The reader must look to Dr. Nichol's book, at page 51, for the picture of this abominable apparition. But then, in order to see what I see, the obedient reader must do what I tell him to do. Let him therefore view the wretch upside down. If he neglects that simple direction, of course I don't answer for anything that follows: without any fault of mine, my description will be unintelligible. This inversion being made, the following is the dreadful creature that will then reveal itself.
Description of the Nebula in Orion, as forced to show out by Lord Rosse.—You see a head thrown back, and raising its face, (or eyes, if eyes it had,) in the very anguish of hatred, to some unknown heavens. What should be its skull wears what might be an Assyrian tiara, only ending behind in a floating train. This head rests upon a beautifully developed neck and throat. All power being given to the awful enemy, he is beautiful where he pleases, in order to point and envenom his ghostly ugliness. The mouth, in that stage of the apocalypse which Sir John Herschel was able to arrest in his eighteen- inch mirror, is amply developed. Brutalities unspeakable sit upon the upper lip, which is confluent with a snout; for separate nostrils there are none. Were it not for this one defect of nostrils; and, even in spite of this defect, (since, in so mysterious a mixture of the angelic and the brutal, we may suppose the sense of odor to work by some compensatory organ,) one is reminded by the phantom's attitude of a passage, ever memorable, in Milton: that passage, I mean, where Death first becomes aware, soon after the original trespass, of his own future empire over man. The 'meagre shadow' even smiles (for the first time and the last) on apprehending his own abominable bliss, by apprehending from afar the savor 'of mortal change on earth.'
——'Such a scent,' (he says,) 'I draw
Of carnage, prey innumerable.'
As illustrating the attitude of the phantom in Orion, let the reader allow me to quote the tremendous passage:—
'So saying, with delight he snuff'd the smell
Of mortal change on earth. As when a flock
Of ravenous fowl, though many a league remote,
Against the day of battle, to a field,
Where armies lie encamp'd, come flying, lured
With scent of living carcasses design'd
For death, the following day, in bloody fight;
So scented the grim feature, [Footnote: 'So scented the grim
feature,' [feature is the old word for form or outline that
is shadowy; and also for form (shadowy or not) which abstracts from
the matter.] By the way, I have never seen it noticed, that
Milton was indebted for the hint of this immortal passage to a superb
line-and-a-half, in Lucan's Pharsalia.] and upturn'd
His nostril wide into the murky air,
Sagacious of his quarry from so far.'
But the lower lip, which is drawn inwards with the curve of a conch shell,—oh what a convolute of cruelty and revenge is there! Cruelty!—to whom? Revenge!—for what? Ask not, whisper not. Look upwards to other mysteries. In the very region of his temples, driving itself downwards into his cruel brain, and breaking the continuity of his diadem, is a horrid chasm, a ravine, a shaft, that many centuries would not traverse; and it is serrated on its posterior wall with a harrow that perhaps is partly hidden. From the anterior wall of this chasm rise, in vertical directions, two processes; one perpendicular, and rigid as a horn, the other streaming forward before some portentous breath. What these could be, seemed doubtful; but now, when further examinations by Sir John Herschel, at the Cape of Good Hope, have filled up the scattered outline with a rich umbrageous growth, one is inclined to regard them as the plumes of a sultan. Dressed he is, therefore, as well as armed. And finally comes Lord Rosse, that glorifies him with the jewellery [Footnote: The jewellery of Stars. And one thing is very remarkable, viz., that not only the stars justify this name of jewellery, as usual, by the life of their splendor, but also, in this case, by their arrangement. No jeweller could have set, or disposed with more art, the magnificent quadrille of stars which is placed immediately below the upright plume. There is also another, a truncated quadrille, wanting only the left hand star (or you might call it a bisected lozenge) placed on the diadem, but obliquely placed as regards the curve of that diadem. Two or three other arrangements are striking, though not equally so, both from their regularity and from their repeating each other, as the forms in a kaleidoscope.] of stars: he is now a vision 'to dream of, not to tell:' he is ready for the worship of those that are tormented in sleep: and the stages of his solemn uncovering by astronomy, first by Sir W. Herschel, secondly, by his son, and finally by Lord Rosse, is like the reversing of some heavenly doom, like the raising of the seals that had been sealed by the angel, in the Revelations. But the reader naturally asks, How does all this concern Lord Rosse's telescope on the one side, or general astronomy on the other? This nebula, he will say, seems a bad kind of fellow by your account; and of course it will not break my heart to hear, that he has had the conceit taken out of him. But in what way can that affect the pretensions of this new instrument; or, if it did, how can the character of the instrument affect the general condition of a science? Besides, is not the science a growth from very ancient times? With great respect for the Earl of Rosse, is it conceivable that he, or any man, by one hour's working the tackle of his new instrument, can have carried any stunning revolutionary effect into the heart of a section so ancient in our mathematical physics? But the reader is to consider, that the ruins made by Lord Rosse, are in sidereal astronomy, which is almost wholly a growth of modern times; and the particular part of it demolished by the new telescope, is almost exclusively the creation of the two Herschels, father and son. Laplace, it is true, adopted their views; and he transferred them to the particular service of our own planetary system. But he gave to them no new sanction, except what arises from showing that they would account for the appearances, as they present themselves to our experience at this day. That was a negative confirmation; by which I mean, that, had their views failed in the hands of Laplace, then they were proved to be false; but, not failing, they were not therefore proved to be true. It was like proving a gun; if the charge is insufficient, or if, in trying the strength of cast iron, timber, ropes, &c., the strain is not up to the rigor of the demand, you go away with perhaps a favorable impression as to the promises of the article; it has stood a moderate trial; it has stood all the trial that offered, which is always something; but you are still obliged to feel that, when the ultimate test is applied, smash may go the whole concern. Lord Rosse applied an ultimate test; and smash went the whole concern. Really I must have laughed, though all the world had been angry, when the shrieks and yells of expiring systems began to reverberate all the way from the belt of Orion; and positively at the very first broadside delivered from this huge four- decker of a telescope.
But what was it then that went to wreck? That is a thing more easy to ask than to answer. At least, for my own part, I complain that some vagueness hangs over all the accounts of the nebular hypothesis. However, in this place a brief sketch will suffice.
Herschel the elder, having greatly improved the telescope, began to observe with special attention a class of remarkable phenomena in the starry world hitherto unstudied, viz.: milky spots in various stages of diffusion. The nature of these appearances soon cleared itself up thus far, that generally they were found to be starry worlds, separated from ours by inconceivable distances, and in that way concealing at first their real nature. The whitish gleam was the mask conferred by the enormity of their remotion. This being so, it might have been supposed that, as was the faintness of these cloudy spots or nebulæ, such was the distance. But that did not follow: for in the treasury of nature it turned out that there were other resources for modifying the powers of distance, for muffling and unmuffling the voice of stars. Suppose a world at the distance x, which distance is so great as to make the manifestation of that world weak, milky, nebular. Now let the secret power that wields these awful orbs, push this world back to a double distance! that should naturally make it paler and more dilute than ever: and yet by compression, by deeper centralization, this effect shall be defeated; by forcing into far closer neighborhood the stars which compose this world, again it shall gleam out brighter when at 2_x_ than when at x. At this point of compression, let the great moulding power a second time push it back; and a second time it will grow faint. But once more let this world be tortured into closer compression, again let the screw be put upon it, and once again it shall shake off the oppression of distance as the dew-drops are shaken from a lion's mane. And thus in fact the mysterious architect plays at hide-and-seek with his worlds. 'I will hide it,' he says, 'and it shall be found again by man; I will withdraw it into distances that shall seem fabulous, and again it shall apparel itself in glorious light; a third time I will plunge it into aboriginal darkness, and upon the vision of man a third time it shall rise with a new epiphany.'
But, says the objector, there is no such world; there is no world that has thus been driven back, and depressed from one deep to a lower deep. Granted: but the same effect, an illustration of the same law, is produced equally, whether you take four worlds, all of the same magnitude, and plunge them simultaneously into four different abysses, sinking by graduated distances one below another, or take one world and plunge it to the same distances successively. So in Geology, when men talk of substances in different stages, or of transitional states, they do not mean that they have watched the same individual stratum or phenomenon, exhibiting states removed from each other by depths of many thousand years; how could they? but they have seen one stage in the case A, another stage in the case B. They take, for instance, three objects, the same (to use the technical language of logic) generically, though numerically different, under separate circumstances, or in different stages of advance. They are one object for logic, they are three for human convenience. So again it might seem impossible to give the history of a rose tree from infancy to age: how could the same rose tree, at the same time, be young and old? Yet by taking the different developments of its flowers, even as they hang on the same tree, from the earliest bud to the full- blown rose, you may in effect pursue this vegetable growth through all its stages: you have before you the bony blushing little rose-bud, and the respectable 'mediæval' full-blown rose.
This point settled, let it now be remarked, that Herschel's resources enabled him to unmask many of these nebulæ: stars they were, and stars he forced them to own themselves. Why should any decent world wear an alias? There was nothing, you know, to be ashamed of in being an honest cluster of stars. Indeed, they seemed to be sensible of this themselves, and they now yielded to the force of Herschel's arguments so far as to show themselves in the new character of nebulæ spangled with stars; these are the stellar nebulæ; quite as much as you could expect in so short a time: Rome was not built in a day: and one must have some respect to stellar feelings. It was noticed, however, that where a bright haze, and not a weak milk- and-water haze, had revealed itself to the telescope, this, arising from a case of compression, (as previously explained,) required very little increase of telescopic power to force him into a fuller confession. He made a clean breast of it. But at length came a dreadful anomaly. A 'nebula' in the constellation Andromeda turned restive: another in Orion, I grieve to say it, still more so. I confine myself to the latter. A very low power sufficed to bring him to a slight confession, which in fact amounted to nothing; the very highest would not persuade him to show a star. 'Just one,' said some coaxing person; 'we'll be satisfied with only one.' But no: he would not. He was hardened, 'he wouldn't split.' And Herschel was thus led, after waiting as long as flesh and blood could wait, to infer two classes of nebulæ; one that were stars; and another that were not stars, nor ever were meant to be stars. Yet that was premature: he found at last, that, though not raised to the peerage of stars, finally they would be so: they were the matter of stars; and by gradual condensation would become suns, whose atmosphere, by a similar process of condensing, would become planets, capable of brilliant literati and philosophers, in several volumes octavo. So stood the case for a long time; it was settled to the satisfaction of Europe that there were two classes of nebulæ, one that were worlds, one that were not, but only the pabulum of future worlds. Silence arose. A voice was heard, 'Let there be Lord Rosse!' and immediately his telescope walked into Orion; destroyed the supposed matter of stars; but, in return, created immeasurable worlds.
As a hint for apprehending the delicacy and difficulty of the process in sidereal astronomy, let the inexperienced reader figure to himself these separate cases of perplexity: 1st, A perplexity where the dilemma arises from the collision between magnitude and distance:—is the size less, or the distance greater? 2dly, Where the dilemma arises between motions, a motion in ourselves doubtfully confounded with a motion in some external body; or, 3dly, Where it arises between possible positions of an object: is it a real proximity that we see between two stars, or simply an apparent proximity from lying in the same visual line, though in far other depths of space? As regards the first dilemma, we may suppose two laws, A and B, absolutely in contradiction, laid down at starting: A, that all fixed stars are precisely at the same distance; in this case every difference in the apparent magnitude will indicate a corresponding difference in the real magnitude, and will measure that difference. B, that all the fixed stars are precisely of the same magnitude; in which case, every variety in the size will indicate a corresponding difference in the distance, and will measure that difference. Nor could we imagine any exception to these inferences from A or from B, whichever of the two were assumed, unless through optical laws that might not equally affect objects under different circumstances; I mean, for instance, that might suffer a disturbance as applied under hypoth. B, to different depths in space, or under hypoth. A, to different arrangements of structure in the star. But thirdly, it is certain, that neither A nor B is the abiding law: and next it becomes an object by science and by instruments to distinguish more readily and more certainly between the cases where the distance has degraded the size, and the cases where the size being really less, has caused an exaggeration of the distance: or again, where the size being really less, yet co-operating with a distance really greater, may degrade the estimate, (though travelling in a right direction,) below the truth; or again where the size being really less, yet counteracted by a distance also less, may equally disturb the truth of human measurements, and so on.
A second large order of equivocating appearances will arise,—not as to magnitude, but as to motion. If it could be a safe assumption, that the system to which our planet is attached were absolutely fixed and motionless, except as regards its own internal relations of movement, then every change outside of us, every motion that the registers of astronomy had established, would be objective and not subjective. It would be safe to pronounce at once that it was a motion in the object contemplated, not in the subject contemplating. Or, reversely, if it were safe to assume as a universal law, that no motion was possible in the starry heavens, then every change of relations in space, between ourselves and them, would indicate and would measure a progress, or regress, on the part of our solar system, in certain known directions. But now, because it is not safe to rest in either assumption, the range of possibilities for which science has to provide, is enlarged; the immediate difficulties are multiplied; but with the result (as in the former case) of reversionally expanding the powers, and consequently the facilities, lodged both in the science and in the arts ministerial to the science. Thus, in the constellation Cygnus, there is a star gradually changing its relation to our system, whose distance from ourselves (as Dr. Nichol tells us) is ascertained to be about six hundred and seventy thousand times our own distance from the sun: that is, neglecting minute accuracy, about six hundred and seventy thousand stages of one hundred million miles each. This point being known, it falls within the arts of astronomy to translate this apparent angular motion into miles; and presuming this change of relation to be not in the star, but really in ourselves, we may deduce the velocity of our course, we may enter into our log daily the rate at which our whole solar system is running. Bessel, it seems, the eminent astronomer who died lately, computed this velocity to be such (viz., three times that of our own earth in its proper orbit) as would carry us to the star in forty-one thousand years. But, in the mean time, the astronomer is to hold in reserve some small share of his attention, some trifle of a side-glance, now and then, to the possibility of an error, after all, in the main assumption: he must watch the indications, if any such should arise, that not ourselves, but the star in Cygnus, is the real party concerned, in drifting at this shocking rate, with no prospect of coming to an anchorage. [Footnote: It is worth adding at this point, whilst the reader remembers without effort the numbers, viz., forty-one thousand years, for the time, (the space being our own distance from the sun repeated six hundred and seventy thousand times,) what would be the time required for reaching, in the body, that distance to which Lord Rosse's six feet mirror has so recently extended our vision. The time would be, as Dr. Nichol computes, about two hundred and fifty millions of years, supposing that our rate of travelling was about three times that of our earth in its orbit. Now, as the velocity is assumed to be the same in both cases, the ratio between the distance (already so tremendous) of Bessel's 61 Cygni, and that of Lord Rosse's farthest frontier, is as forty- one thousand to two hundred and fifty millions. This is a simple rule- of-three problem for a child. And the answer to it will, perhaps, convey the simplest expression of the superhuman power lodged in the new telescope:—as is the ratio of forty-one thousand to two hundred and fifty million, so is the ratio of our own distance from the sun multiplied by six hundred and seventy thousand, to the outermost limit of Lord Rosse's sidereal vision.]
Another class, and a frequent one, of equivocal phenomena, phenomena that are reconcilable indifferently with either of two assumptions, though less plausibly reconciled with the one than with the other, concerns the position of stars that seem connected with each other by systematic relations, and which yet may lie in very different depths of space, being brought into seeming connection only by the human eye. There have been, and there are, cases where two stars dissemble an interconnection which they really have, and other cases where they simulate an interconnection which they have not. All these cases of simulation and dissimulation torment the astronomer by multiplying his perplexities, and deepening the difficulty of escaping them. He cannot get at the truth: in many cases, magnitude and distance are in collusion with each other to deceive him: motion subjective is in collusion with motion objective; duplex systems are in collusion with fraudulent stars, having no real partnership whatever, but mimicking such a partnership by means of the limitations or errors affecting the human eye, where it can apply no other sense to aid or to correct itself. So that the business of astronomy, in these days, is no sinecure, as the reader perceives. And by another evidence, it is continually becoming less of a sinecure. Formerly, one or two men,— Tycho, suppose, or, in a later age, Cassini and Horrox, and Bradley, had observatories: one man, suppose, observed the stars for all Christendom; and the rest of Europe observed him. But now, up and down Europe, from the deep blue of Italian skies to the cold frosty atmospheres of St. Petersburg and Glasgow, the stars are conscious of being watched everywhere; and if all astronomers do not publish their observations, all use them in their speculations. New and brilliantly appointed observatories are rising in every latitude, or risen; and none, by the way, of these new-born observatories, is more interesting from the circumstances of its position, or more picturesque to a higher organ than the eye—viz., to the human heart—than the New Observatory raised by the university of Glasgow.[Footnote: It has been reported, ever since the autumn of 1845, and the report is now, (August, 1846,) gathering strength, that some railway potentate, having taken a fancy for the ancient college of Glasgow, as a bauble to hang about his wife's neck, (no accounting for tastes,) has offered, (or will offer,) such a price, that the good old academic lady in this her moss-grown antiquity, seriously thinks of taking him at his word, packing up her traps, and being off. When a spirit of galavanting comes across an aged lady, it is always difficult to know where it will stop: so, in fact, you know, she may choose to steam for Texas. But the present impression is, that she will settle down by the side of what you may call her married or settled daughter—the Observatory; which one would be glad to have confirmed, as indicating that no purpose of pleasure-seeking had been working in elderly minds, but the instinct of religious rest and aspiration. The Observatory would thus remind one of those early Christian anchorites, and self-exiled visionaries, that being led by almost a necessity of nature to take up their residence in deserts, sometimes drew after themselves the whole of their own neighborhood.]
The New Observatory of Glasgow is now, I believe, finished; and the only fact connected with its history that was painful, as embodying and recording that Vandal alienation from science, literature, and all their interests, which has ever marked our too haughty and Caliph-Omar- like British government, lay in the circumstance that the glasses of the apparatus, the whole mounting of the establishment, in so far as it was a scientific establishment, and even the workmen for putting up the machinery, were imported from Bavaria. We, that once bade the world stand aside when the question arose about glasses, or the graduation of instruments, were now literally obliged to stand cap in hand, bowing to Mr. Somebody, successor of Frauenhofer or Frauendevil, in Munich! Who caused that, we should all be glad to know, if not the wicked Treasury, that killed the hen that laid the golden eggs by taxing her until her spine broke? It is to be hoped that, at this moment, and specifically for this offence, some scores of Exchequer men, chancellors and other rubbish, are in purgatory, and perhaps working, with shirt-sleeves tucked up, in purgatorial glass-houses, with very small allowances of beer, to defray the cost of perspiration. But why trouble a festal remembrance with commemorations of crimes or criminals? What makes the Glasgow Observatory so peculiarly interesting, is its position, connected with and overlooking so vast a city, having more than three hundred thousand inhabitants, (in spite of an American sceptic,) nearly all children of toil; and a city, too, which, from the necessities of its circumstances, draws so deeply upon that fountain of misery and guilt which some ordinance, as ancient as 'our father Jacob,' with his patriarchal well for Samaria, has bequeathed to manufacturing towns,—to Ninevehs, to Babylons, to Tyres. How tarnished with eternal canopies of smoke, and of sorrow; how dark with agitations of many orders, is the mighty town below! How serene, how quiet, how lifted above the confusion and the roar, how liberated from the strifes of earth, is the solemn Observatory that crowns the grounds above! And duly, at night, just when the toil of over-wrought Glasgow is mercifully relaxing, then comes the summons to the laboring astronomer. He speaks not of the night, but of the day and the flaunting day-light, as the hours 'in which no man can work.' And the least reflecting of men must be impressed by the idea, that at wide intervals, but intervals scattered over Europe, whilst 'all that mighty heart' is, by sleep, resting from its labors, secret eyes are lifted up to heaven in astronomical watch-towers; eyes that keep watch and ward over spaces that make us dizzy to remember, eyes that register the promises of comets, and disentangle the labyrinths of worlds.
Another feature of interest, connected with the Glasgow Observatory, is personal, and founded on the intellectual characteristics of the present professor, Dr. Nichol; in the deep meditative style of his mind seeking for rest, yet placed in conflict for ever with the tumultuous necessity in him for travelling along the line of revolutionary thought, and following it loyally, wearied or not, to its natural home.
In a sonnet of Milton, one of three connected with his own blindness, he distinguishes between two classes of servants that minister to the purposes of God. 'His state,' says he, meaning God's state, the arrangement of his regular service, 'is kingly;' that is to say, it resembles the mode of service established in the courts of kings; and, in this, it resembles that service, that there are two classes of ministers attending on his pleasure. For, as in the trains of kings are some that run without resting, night or day, to carry the royal messages, and also others—great lords in waiting—that move not from the royal gates; so of the divine retinues, some are for action only, some for contemplation. 'Thousands' there are that
——'at his bidding speed, And post o'er land and ocean without rest.'
Others, on the contrary, motionless as statues, that share not in the agitations of their times, that tremble not in sympathy with the storms around them, but that listen—that watch—that wait—for secret indications to be fulfilled, or secret signs to be deciphered. And, of this latter class, he adds-that they, not less than the others, are accepted by God; or, as it is so exquisitely expressed in the closing line,
'They also serve, that only stand and wait.'
Something analogous to this one may see in the distributions of literature and science. Many popularize and diffuse: some reap and gather on their own account. Many translate, into languages fit for the multitude, messages which they receive from human voices: some listen, like Kubla Khan, far down in caverns or hanging over subterranean rivers, for secret whispers that mingle and confuse themselves with the general uproar of torrents, but which can be detected and kept apart by the obstinate prophetic ear, which spells into words and ominous sentences the distracted syllables of ærial voices. Dr. Nichol is one of those who pass to and fro between these classes; and has the rare function of keeping open their vital communications. As a popularizing astronomer, he has done more for the benefit of his great science than all the rest of Europe combined: and now, when he notices, without murmur, the fact that his office of popular teacher is almost taken out of his hands, (so many are they who have trained of late for the duty,) that change has, in fact, been accomplished through knowledge, through explanations, through suggestions, dispersed and prompted by himself.
For my own part, as one belonging to the laity, and not to the clerus, in the science of astronomy, I could scarcely have presumed to report minutely, or to sit in the character of dissector upon the separate details of Dr. Nichol's works, either this, or those which have preceded it, had there even been room left disposable for such a task. But in this view it is sufficient to have made the general acknowledgment which already has been made, that Dr. Nichol's works, and his oral lectures upon astronomy, are to be considered as the fundus of the knowledge on that science now working in this generation. More important it is, and more in reconciliation with the tenor of my own ordinary studies, to notice the philosophic spirit in which Dr. Nichol's works are framed; the breadth of his views, the eternal tendency of his steps in advance, or (if advance on that quarter, or at that point, happens to be absolutely walled out for the present,) the vigor of the reconnoissances by which he examines the hostile intrenchments. Another feature challenges notice. In reading astronomical works, there arises (from old experience of what is usually most faulty) a wish either for the naked severities of science, with a total abstinence from all display of enthusiasm; or else, if the cravings of human sensibility are to be met and gratified, that it shall be by an enthusiasm unaffected and grand as its subject. Of that kind is the enthusiasm of Dr. Nichol. The grandeurs of astronomy are such to him who has a capacity for being grandly moved. They are none at all to him who has not. To the mean they become meannesses. Space, for example, has no grandeur to him who has no space in the theatre of his own brain. I know writers who report the marvels of velocity, &c., in such a way that they become insults to yourself. It is obvious that in their way of insisting on our earth's speed in her annual orbit, they do not seek to exalt her, but to mortify you. And, besides, these fellows are answerable for provoking people into fibs:—for I remember one day, that reading a statement of this nature, about how many things the Earth had done that we could never hope to do, and about the number of cannon balls, harnessed as a tandem, which the Earth would fly past, without leaving time to say, How are you off for soap? in vexation of heart I could not help exclaiming—'That's nothing: I've done a great deal more myself;' though, when one turns it in one's mind, you know there must be some inaccuracy there. How different is Dr. Nichol's enthusiasm from this hypocritical and vulgar wonderment! It shows itself not merely in reflecting the grandeurs of his theme, and by the sure test of detecting and allying itself with all the indirect grandeurs that arrange themselves from any distance, upon or about that centre, but by the manifest promptness with which Dr. Nichol's enthusiasm awakens itself upon every road that leads to things elevating for man; or to things promising for knowledge; or to things which, like dubious theories or imperfect attempts at systematizing, though neutral as regards knowledge, minister to what is greater than knowledge, viz., to intellectual power, to the augmented power of handling your materials, though with no more materials than before. In his geological and cosmological inquiries, in his casual speculations, the same quality of intellect betrays itself; the intellect that labors in sympathy with the laboring nisus of these gladiatorial times; that works (and sees the necessity of working) the apparatus of many sciences towards a composite result; the intellect that retires in one direction only to make head in another; and that already is prefiguring the route beyond the barriers, whilst yet the gates are locked.
