Betides, a knowledge of thefe names, together with an ac-
quaintance with the general properties and manner of drawing
fuch figures, muff certainly be confidered as an introductory
ilep to a more advanced knowledge of Geometry, by thofe
young men who intend to rife higher in this fublime fcience,
than can be expected to be taught in a drawing-book.

afterwards defcribe the conftruCtion, or manner of drawing, the
moft generally ufeful figures.
'Of the Superficies (See Plate II.)
No. i, is a Geometrical Square, fo called becaufe it has four
tides of equal length, and four right angles.
No. 2, is a Parallelogram. This figure receives its name
from its oppofite fides and ends being all parallel to each other.
No. 3, a Rhomb, which is properly a geometrical fquare
moved out of its pofition, fince all its tides are equal, but not
its angles, two of them being acute, and the other obtufe.
