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 _nebulae_, 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
