tation in asserting that we are _in the midst_ of that inconceivable host of stars--of suns--of systems--which constitute the Galaxy. Moreover, not only have _we_--not only has _our_ Sun a right to claim the Galaxy as its own especial cluster, but, with slight reservation, it may be said that all the distinctly visible stars of the firmament--all the stars Visible to the naked eye--have equally a right to claim it as _their_ own. There has been a great deal of misconception in respect to the _shape_ of the Galaxy; which, in nearly all our astronomical treatises, is said to resemble that of a capital Y. The cluster in question has, in reality, a certain general--_very_ general resemblance to the planet Saturn, with its encompassing triple ring. Instead of the solid orb of that planet, however, we must picture to ourselves a lenticular star-island, or collection of stars; our Sun lying excentrically--near the shore of the island--on that side of it which is nearest the constellation of the Cross and farthest from that of Cassiopeia. The surrounding ring, where it approaches our position, has in it a longitudinal _gash_, which does, in fact, cause _the ring, in our vicinity_, to assume, loosely, the appearance of a capital Y. We must not fall into the error, however, of conceiving the somewhat indefinite girdle as at all _remote_, comparatively speaking, from the also indefinite lenticular cluster which it surrounds; and thus, for mere purpose of explanation, we may speak of our Sun as actually situated at that point of the Y where its three component lines unite; and, conceiving this letter to be of a certain solidity--of a certain thickness, very trivial in comparison with its length--we may even speak of our position as _in the middle_ of this thickness. Fancying ourselves thus placed, we shall no longer find difficulty in accounting for the phaenomena presented--which are perspective altogether. When we look upward or downward--that is to say, when we cast our eyes in the direction of the letter's _thickness_--we look through fewer stars than when we cast them in the direction of its _length_, or _along_ either of the three component lines. Of course, in the former case, the stars appear scattered--in the latter, crowded.--To reverse this explanation:--An inhabitant of the Earth, when looking, as we commonly express ourselves, _at_ the Galaxy, is then beholding it in some of the directions of its length--is looking
