where he may at ſome diſtance, diſcern the
place on which the Cloud does caſt its ſhadow,
and withal does obſerve, how much both the
Cloud and the Sun decline from the Vertical
point. From which he may eaſily conclude
the true Altitude of it, as you may more plain-
ly conceive, by this following Diagram.

Where A B is a perpendicular from the cloud,
G the Station of him that meaſures, D the place
where the ſhadow of the Cloud doth fall.

The inſtrument being directed from the Sta-
tion G, to the Cloud at A, the perpendicular
will ſhew the Angle B A G. Then letting the
Sun ſhine through the ſights of your Inſtru-
ment, the perpendicular of it will give the
Angle B A D. After wards having meaſured

gon. the diſtance G D by paces, you may, according
to the common Rules, find the height B A.
