lute dimensions, when stated in miles, leagues, or any units familiar to the human experience, they are too stunning and confounding. If, again, they are stated in larger units, as for instance diameters of the earth's orbit, the unit itself that should facilitate the grasping of the result, and which really is more manageable numerically, becomes itself elusive of the mental grasp: it comes in as an interpreter; and (as in some other cases) the interpreter is hardest to be understood of the two. If, finally, TIME be assumed as the exponent of the dreadful magnitudes, time combining itself with motion, as in the flight of cannon-balls or the flight of swallows, the sublimity becomes greater; but horror seizes upon the reflecting intellect, and incredulity upon the irreflective. Even a railroad generation, that should have faith in the miracles of velocity, lifts up its hands with an‘Incredulus odi!' we know that Dr. Nichol speaks the truth; but he seems to speak falsehood. And the ignorant by-stander prays that the doctor may have grace given him and time for repentance; whilst his more liberal companion reproves his want of charity, observing that travellers into far countries have always had a license for lying, as a sort of tax or fine levied for remunerating their own risks; and that great astronomers, as necessarily far travellers into space, are entitled to a double per centage of the same Munchausen privilege.

Great is the mystery of Space, greater is the mystery of Time; either mystery grows upon man, as man himself grows; and either seems to be a function of the godlike which is in man. In reality the

depths and the heights which are in man, the depths by which he searches, the heights by which he aspires, are but projected and made objective externally in the three dimensions of space which are outside of him. He trembles at the abyss into which his bodily eyes look down, or look up; not knowing that abyss to be, not always consciously suspecting it to be, but by an instinct written in his prophetic heart feeling it to be, boding it to be, fearing it to be, and sometimes hoping it to be, the mirror to a mightier abyss that will one day be expanded in himself. Even as to the sense of space, which is the lesser mystery than time, I know not whether the reader has remarked that it is one which swells upon man with the expansion of his mind, and that it is probably peculiar to the mind of man. An infant of a year old, or oftentimes even older, takes no notice of a sound, however loud, which is a quarter of a mile removed, or even in a distant chamber. And brutes, even of the most enlarged capacities, seem not to have any commerce with distance: distance is probably not revealed to them except by a presence, viz., by some shadow of their own animality, which, if perceived at all, is perceived as a thing present to their organs. An animal desire, or a deep animal hostility, may render sensible a distance which else would not be sensible; but not render it sensible as a distance. Hence perhaps is explained, and not out of any self-oblivion from higher enthusiasm, a fact that often has occurred, of deer, or hares, or foxes, and the pack of hounds in pursuit, chaser and chased, all going headlong over a precipice together. Depth

or height does not readily manifest itself to them; so that any strong motive is sufficient to overpower the sense of it. Man only has a natural function for expanding on an illimitable sensorium, the illimitable growths of space. Man, coming to the precipice, reads his danger; the brute perishes: man is saved; and the horse is saved by his rider.

But, if this sounds in the ear of some a doubtful refinement, the doubt applies only to the lowest degrees of space. For the highest, it is certain that brutes have no perception. To man is as much reserved the prerogative of perceiving space in its higher extensions, as of geometrically constructing the relations of space. And the brute is no more capable of apprehending abysses through his eye, than he can build upwards or can analyze downwards the aerial synthesis of Geometry. Such, therefore, as is space for the grandeur of man's perceptions, such as is space for the benefit of man's towering mathematic speculations, such is the nature of our debt to Lord Rosse as being the philosopher who has most pushed back the frontiers of our conquests upon this exclusive inheritance of man. We have all heard of a king that, sitting on the sea-shore, bade the waves, as they began to lave his feet, upon their allegiance to retire. That was said not vainly or presumptuously, but in reproof of sycophantic courtiers. Now, however, we see in good earnest another man, wielding another kind of sceptre, and sitting upon the shores of infinity, that says to the ice which had frozen up our progress, 'Melt thou before my breath!' that says to the rebellious nebulæ, — Sub

mit, and burst into blazing worlds!' that says to the gates of darkness,—'Roll back, ye barriers, and no longer hide from us the infinities of God!'

'Come, and I will show you what is beautiful.'

From the days of infancy still lingers in my ears this opening of a prose hymn by a lady, then very celebrated, viz., the late Mrs. Barbauld. The hymn began by enticing some solitary infant into some silent garden, I believe, or some forest lawn; and the opening words were, 'Come, and I will show you what is beautiful!' Well, and what beside? There

is nothing beside; oh, disappointed and therefore enraged reader; positively this is the sum-total of what I can recall from the wreck of years; and certainly it is not much. Even of Sappho, though time has made mere ducks and drakes of her lyrics, we have rather more spared to us than this. And yet this trifle, simple as you think it, this shred of a fragment, if the reader will believe me, still echoes with luxurious sweetness in my ears, from some unaccountable hide-and-seek of fugitive childish memories; just as a marine shell, if applied steadily to the ear, awakens (according to the fine image of Landor5) the great vision of the sea; places the listener

'In the sun's palace-porch,

And murmurs as the ocean murmurs there.'

Now, on some moonless night, in some fitting condition of the atmosphere, if Lord Rosse would permit the reader and myself to walk into the front drawingroom of his telescope, then, in Mrs. Barbauld's words,

slightly varied, I might say to him, -Come, and I will show you what is sublime! In fact, what I am going to lay before him, from Dr. Nichol's work, is, or at least would be, (when translated into Hebrew grandeur by the mighty telescope,) a step above even that object which some four-and-twenty years ago in the British Museum struck me as simply the sublimest sight which in this sight-seeing world I had seen. It was the Memnon's head, then recently brought from Egypt. I looked at it, as the reader must suppose, in order to understand the depth which I have here ascribed to the impression, not as a human but as a symbolic head; and what it symbolized to me were: 1. The peace which passeth all understanding. 2. The eternity which baffles and confounds all faculty of computation; the eternity which had been, the eternity which was to be. 3. The diffusive love, not such as rises and falls upon waves of life and mortality, not such as sinks and swells by undulations of time, but a procession -an emanation from some mystery of endless dawn. You durst not call it a smile that radiated from the lips; the radiation was too awful to clothe itself in adumbrations or memorials of flesh.

In that mode of sublimity, perhaps, I still adhere to my first opinion, that nothing so great was ever beheld. The atmosphere for this, for the Memnon, was the breathlessness which belongs to a saintly trance; the holy thing seemed to live by silence. But there is a picture, the pendant of the Memnon, there is a dreadful cartoon, from the gallery which has begun to open upon Lord Rosse's telescope,
