Example IX. Fig. 36. Plate XXIV.
How to reprefeni a Chair having its Front perpendicular to
the Picture.

In this example the fame ground line, horizon^ center, and
diftance, is ufed as in the preceding; therefore let the fpace 7, 1,
be equal to the length of the chair front. From 7 draw a line
to s, and from 1 draw a line to the diftance, cutting at 16.
Make 7,9 equal to the length of the fide rail, and from 9 draw
a line* to j; make 9,10 the thicknefs of the back foot, and from
10 draw a line to r, as before. Draw a parallel line for the
depth of the tide rail, and from 8 draw a line to r. Next con-
fider how much the back foot fweeps off from the perpendicu-
lar, which is equal to the fpace 12,13, or 2, 22 ; draw vifuals
from each of thefe points, as the example direds. To find the
bevel of the fides, take C D and place it from 7 to 5, and from 1
to 3; from which draw lines to the diftance, cutting at 11 and
17; from 11 and 17 draw parallels cutting the vifual 91 at 20
and 18 ; from 7 draw a line to 20, and from 16 draw one to 18,
which will finifh the outline of the feat. Laftly, from 18
and 20 let fall perpendiculars, cutting at 24, 25 ; from which
draw parallels to the vifual 13 which gives the bottom of
8 each
