Gnomonic projection, a projection of the circles of the
sphere, in which the point of sight is taken at the center
of the sphere, and the principal plane is tangent to the
surface of the sphere. "The gnomonic projection derives
its name from the connection between the methods of
describing it and those for the construction of a gnomon
or dial." --Cyc. of Arts & Sciences.

4. (Persp.) The representation of something; delineation;
plan; especially, the representation of any object on a
perspective plane, or such a delineation as would result
were the chief points of the object thrown forward upon
the plane, each in the direction of a line drawn through
it from a given point of sight, or central point; as, the
projection of a sphere. The several kinds of projection

Mercator's projection, a mode of representing the sphere in
which the meridians are drawn parallel to each other, and
the parallels of latitude are straight lines whose
distance from each other increases with their distance
from the equator, so that at all places the degrees of
latitude and longitude have to each other the same ratio
as on the sphere itself.
Oblique projection, a projection made by parallel lines
drawn from every point of a figure and meeting the plane
of projection obliquely.
Polar projection, a projection of the sphere in which the
point of sight is at the center, and the plane of
projection passes through one of the polar circles.
Powder of projection (Alchemy.), a certain powder cast into
a crucible or other vessel containing prepared metal or
other matter which is to be thereby transmuted into gold.
Projection of a point on a plane (Descriptive Geom.), the
