The Mathematicall Praeface to Elements of Geometrie of Euclid of Megara

Or, how High or depe, aboue or vnder the leuel of the measurers stãding,
any thing is, which is sene on land or water, called _Hypsometrie_.
[3.]
* Or, it informeth the measurer, how Broad any thing is, which is in the
measurers vew: so it be on Land or Water, situated: and may be called
_Platometrie_. Though I vse here to condition, the thing measured, to be
on Land, or Water Situated:
[Note.]
yet, know for certaine, that the sundry heigthe of Cloudes, blasing
Starres, and of the Mone, may (by these meanes) haue their distances
from the earth: and, of the blasing Starres and Mone, the Soliditie
(aswell as distances) to be measured: But because, neither these things
are vulgarly taught: nor of a common practiser so ready to be executed:
I, rather, let such measures be reckened incident to some of our other
Artes, dealing with thinges on high, more purposely, then this vulgar
Land measuring Geometrie doth: as in _Perspectiue_ and _Astronomie, &c._
Of these Feates (farther applied) is Sprong the Feate of _Geodesie_, or
Land Measuring: more cunningly to measure & Suruey Land, Woods, and
Waters, a farre of. More cunningly, I say: But God knoweth (hitherto) in
these Realmes of England and Ireland (whether through ignorance or
fraude, I can not tell, in euery particular)
[Note.]
how great wrong and iniurie hath (in my time) bene committed by vntrue
measuring and surueying of Land or Woods, any way. And, this I am sure:
that the Value of the difference, betwene the truth and such Surueyes,
would haue bene hable to haue foũd (for euer) in eche of our two
Vniuersities, an excellent Mathematicall Reader: to eche, allowing
(yearly) a hundred Markes of lawfull money of this realme: which, in
dede, would seme requisit, here, to be had (though by other wayes
prouided for) as well, as, the famous Vniuersitie of Paris, hath two
Mathematicall Readers: and eche, two hundreth French Crownes yearly, of
the French Kinges magnificent liberalitie onely. Now, againe, to our
purpose returning: Moreouer, of the former knowledge Geometricall, are
growen the Skills of _Geographie_, _Chorographie_, _Hydrographie_, and
_Stratarithmetrie_.
