equilateral triangle, whofe perpendicular will be at w; then
will s w be the diftance propofed in this cafe. But if the piece
of furniture be of an extraordinary length in front, in propor-
tion to its breadth from back to front, then it will be belt to
adopt the preceding method; for if we fuppofe the piece of
furniture to extend from 7 to 9, then a perpendicular of an
equilateral triangle of that dimenfion added to the whole height
of the horizon, would forefhorten too much. Of thefe things I
am perfuaded the reader will be convinced, if he make the ex-
periment as the cafes are here dated.
Of the Repref ent ations of circular and curvilinear Figures,
both plain and folid\ together with fame Remarks on their
Theory.
The manner in which fome painters and defigners treat
circular objects, would lead one to fuppofe that there is no cer-
tain theory on which to build the practice of drawing objects of
that kind.
Sometimes we may fee a calk, if not fhewing both ends, yet
the end on which it Hands is reprefented by a curve confider-
ably more flat than that by which its top is fhewn; than
which nothing can be more abfurd, for the very reverfe is the
truth.*
