[Sidenote: The _Milky Way_.]
400. There is a remarkable track round the Heavens, called the _Milky
Way_ from its peculiar whiteness, which is owing to a great number of
Stars scattered therein; none of which can be distinctly seen without
telescopes. This track appears single in some parts, in others double.
[Sidenote: Lucid Spots.]
401. There are several little whitish spots in the Heavens, which appear
magnified, and more luminous when seen through telescopes; yet without
any Stars in them. One of these is in _Andromeda_’s girdle, first
observed _A. D._ 1612, by _Simon Marius_; and which has some whitish
rays near its middle: it is liable to several changes, and is sometimes
invisible. Another is near the Ecliptic, between the head and bow of
_Sagittarius_: it is small, but very luminous. A third is on the back of
the _Centaur_, which is too far South to be seen in _Britain_. A fourth,
of a smaller size, is before _Antinous_’s right foot; having a Star in
it, which makes it appear more bright. A fifth is in the Constellation
of _Hercules_, between the Stars ζ and η, which spot, though but small,
is visible to the bare eye if the sky be clear and the Moon absent.
[Sidenote: Cloudy Stars.
Magellanic Clouds.]
