Lastly, G star jeans One other fact connected with our system, remains to be noticed—one especially dwelt on by Sir John Hcrschel—in that worifon the Southern Skies, in which he has G star raw worthily closed the greatest, most complete, and G-star outlet most classical series of inquiries yet possessed by sidereal astronomy. On the background of the sky, in regions not apparently connected either with the Milky Way, or any foreign cluster, this acute observer has been frequently called on to remark, instead of that perfect darkness usually characterizing recesses which no star illumines, " an exceedingly delicate and uniform dotting, or itippling of the fitld in view, by points of light too small to admit of any one being steadily or fixedly examined, and too numerous for counting, were it possible, so to view them." He has specified no fewer than thirty-seven places distinguished by this strange and evanescent presence, G star the shadowas of some fur away reality, or light blushin: through darkness. The phenomenon, indeed, so faint, that he says, " The idea of illusion ha continually arisen subsequently;" but as to it reality, it is enough to G-star read from Sir John note book, ' I feel satisfied the stippling is no llusion, as its dark mottling moves with the stars as I move the tube to and fro;" and more that is similar. What are these fresh intimations from beyond abysses so awful? On examining, by aid of a stellar chart, whether the patches of light could be grouped in any consistent or intelligible manner, the same astronomer found that, with the exception of three that appear outlying and disconnected, they form several distinct but continuous streams; and it seems, therefore, that as they must be held to be starry regions of great extent and excessive remoteness, we are constrained -to consider them branchesor arms of the system of our Milky Way, amid depths to which no adventurous conception ever penetrated before.
