15. The _Ocean_, or _Main Sea_, is a vast spreading collection of water, not divided or separated by lands running between; such is the _Atlantic_ or _Western Ocean_; between _Europe_ and _America_; the _Pacific Ocean_, or _South Sea_, &c. _Note_, Those parts of the ocean which border upon the land, are called by various names, according to those of the adjacent countries; as, the _British Sea_, the _Irish Sea_, the _French_ and _Spanish Sea_. [Sidenote: _A Lake._] 16. A _Lake_ is a collection of deep standing water, inclosed all round with land, and not having any visible and open communication with the sea: But when this lake is very large, it is commonly called a sea; as the _Caspian Sea_ in _Asia_, &c. [Sidenote: _A Gulf._] [Sidenote: _Creek_ or _Haven_.] 17. A _Gulf_ is a part of the sea almost encompassed with land, or that which runs up a great way into the land; as, the _Gulf_ of _Venice, &c._ But if it be very large, ’tis rather called an _Inland Sea_; as the _Baltic Sea_, the _Mediterranean Sea_, the _Red Sea_, or the _Arabian Gulf, &c._ And a small part of sea thus environed with land is usually called a _Bay_. If it be but a very small Part, or, as it were, a small arm of the sea, that runs but a few miles between the land, it is called a _Creek_ or _Haven_. [Sidenote: _A Strait._] 18. A _Strait_ is a narrow passage lying between two shores, whereby two seas are joined together; as, the _Straits_ of _Dover_, between the _British Channel_ and the _German Sea_; the _Straits_ of _Gibralter_, between the _Atlantic_ and the _Mediterranean Sea_. The _Mediterranean_ itself is also sometimes called the _Straits_. These are all the necessary terms commonly used in _Geography_. The names of the several countries and seas, and all the principal divisions of the Earth, the reader will find expressed upon the Terrestrial Globes. To give a tolerable account of the produce of each country, the genius of the people, their political institutions, _&c._ is properly a particular subject of itself, and quite foreign to our design. We shall next proceed to the use of the Globes; but first it may not be amiss to take a short _review_ of their appurtenances. Those circles of the sphere that are _fixed_, are (as has been already said) drawn upon the _Globes_ themselves; those that are _moveable_, are supplied by the _Brass Meridian_, the _Wooden Horizon_, and the _Quadrant of Altitude_.
