SECTION IV.
Of the reprefdntatlons of Polygonal and Curvilinear Figures—con-
taining fome further Remarks on the difference between the Re-
prefentation of Objects on a Plane, and their real Appearance to
the Eye—Of long and Jhort diftances, and the Reprefentation of
a Row of Columns and Pilajlers, parallel to the Picture; to-
gether with fome Obfervations on the theory of Circular
Objects.
Of Polygonal Figures.
Lines in three different pofitions to the picture, will re-
prefent any polygon in any fituation whatever *.
A pentagon may have one fide parallel to the picture; and
if fo, the other four will be oblique to it; or it may be placed
fo as to have all its fides oblique.
* See the definition in page 49, and the various kinds of polygons in Plate II.
