ases are Epidemical, that are supposed to flow from
the Air: What other diseases, wherein _that_ hath a share, the Countrey is
subject to; the Plague and Contagious sicknesses: What is the usual
salubrity or insalubrity of the Air; and with what Constitutions it agrees
better or worse, than others.

3. About the _Water_, may be observ'd, the Sea, its Depth, degree of
Saltness, Tydes, Currents, &c. _Next_, Rivers, their Bigness, Length,
Course, Inundations, Goodness, Levity (or their Contraries) of Waters, &c.
_Then_, Lakes, Ponds, Springs, and especially Mineral waters, their Kinds,
Qualities, Vertues, and how examined. To the _Waters_ belong also _Fishes_,
what kinds of them (whether Salt or Fresh-water fish) are to be found in
the Country; their Store, Bigness, Goodness, Seasons, Haunts, Peculiarities
of any kind, and the wayes of taking them, especially those that are not
purely _Mechanical_.

4. In the _Earth_, may be observed,

1. _It self._

2. Its _Inhabitants_, and its _Productions_, and these _External_, and
_Internal_.

_First_, in the Earth _it self_, may be observ'd, its dimensions,
scituation, East, West, North, and South: its Figure, its Plains, and
Valleys, and their Extent; its Hills and Mountains, and the height of the
tallest, both in reference to the neighbouring Valleys or Plains, and in
reference to the Level of the Sea: As {188} also, whether the Mountains lye
scattered, or in ridges, and whether those run North and South, or East and
West, &c. What Promontories, fiery or smoaking Hills, &c. the Country has,
or hath not: Whether the Country be coherent, or much broken into Ilands.
What the Magnetical Declination is in several places, and the Variations of
that Declination in the same place (and, if either of those be very
considerable, then, what circumstances may assist one to guess at the
Reason as Subterraneal fires, the Vicinity of Iron-mines, &c.) what the
Nature of the Soyle is, whether Clays, Sandy, &c. or good Mould; and what
Grains, Fruits, and other Vegetables, do the most naturally agree with it:
As also, by what particular Arts and Industries the Inhabitants improve the
Advantages, and remedy the Inconveniences of their Soyl: What hidden
qualities the Soyl may have (as that of _Ireland_, against Venemous Beasts,
&c.)

_Secondly_, above the ignobler _Productions_ of the Earth, there must be a
careful account given of the _Inhabitants_ themselves, both _Natives_ and
_St
