III. _Of the Poetical rising and setting of the Stars._

[Sidenote: _Cosmical_, _Acronical_, and _Heliacal rising_ and

_setting_.]

The ancient Poets make frequent mention of the Stars rising and

setting, either _Cosmically_, _Acronically_, or _Heliacally_; whence

these distinctions are called _Poetical_.

A Star is said to _rise_ or _set Cosmically_, when it rises or sets at

Sun-rising; and when it _rises_ or _sets_ at Sun-setting, it is said

to rise or set _Acronically_. A Star _rises Heliacally_, when first it

becomes visible, after it had been so near the Sun as to be hid by the

splendor of his rays: And a Star is said to _set Heliacally_, when it

is first immersed, or hid by the Sun’s rays.

The _Fixed Stars_, and the three superior Planets, _Mars_, _Jupiter_,

and _Saturn_, rise _Heliacally_ in the morning; but the Moon rises

_Heliacally_ in the evening, because the Sun is swifter than the

superior Planets, and slower than the Moon.

IV. _Of the surface of the Earth, considered as it is composed of Land

and Water._

The Earth consists naturally of two parts, Land and Water, and

therefore it is called the _Terraqueous Globe_. Each of these elements

is subdivided into various forms and parts, which accordingly are

distinguished by different names.
