rious directions to his original lines, or by drawing
on the right hand, what is here given to the left, or
by any other change which fancy may fugged.
It isalfo proper to remark, that the conftruction of
horizontal pictures is precifely the fame as that of
vertical pictures, which is eafily experimented by
looking up to the ceiling ; in which cafe, the center
beam or ray from the eye equally regulates every
other line: the fame if a perfon from a high para-
pet looks down to the ground; the wall of the houfe
which fupports the parapet, anfwers to the fituation
of a horizontal plane, and the ground is to him ver-
tical. But as it is hardly to be fuppofed that our
readers (hould undertake fuch fubjecis, the prefent
hint is thought fufficient without examples.
Perfpeciive has by fome perfons been applied to
reprefent as receding what really approaches, and to
bring- forward what retires: but at the fame time
that this is allowed to be curious, it is equally con-
sidered as ufelefs, and merely is the effect of irregu-
lar furfaces forming one picture.
It is amazing to fee the errors committed by ar-
tifts (not otherwife without merit) in their reprefen-
tations of fun dry objects, and even frequently of
fpaces and dillances: whereas, if they would infert
on their defigns merely three or four of the principal
directing lines, they could not polBbly commit fuch

vifeable to make ufe of a height correfpondent to
