Of
bed by. On the perpendicular line now mentioned lay on the
diftance of the picture from the horizontal line. Then deter-
mine the pofition of one fide of the bed, by drawing a line from
the angle E to V; from V drawr a line to the diftance here out
of the plate, on the aforefaid perpendicular; from the diftance
draw a line T U at right angles with this, which produced cuts
the horizon, and finds the vanifhing point for the ends of the
bed; confequently V is the vanifhing point for the fides of the
bed. From 7 to A is feven feet, the length of the fide; and
from 7 to N is the width of the bed. From N A draw lines to
D D, the dividing centers, or meafuring points, found as in
Problem VI. Method 2. page 237, which will cut the vifuals for
the apparent length and width of the bed. A perpendicular
from 5 is the center of the end of the bed; S is the original '
height of the dome, from which a line is directed to the right
hand vanifhing point, cutting at d\ a line from d finds the cen-
ter of fthe dome, and V the top ,of the pine-apple; c a give the
height of the cornice; the diagonals 1, 3, 2,4, find the center of
the dome, by railing a perpendicular from their interfecliom
Every other thing will follow of courfe to him who has previ-
oufly ftudied the rules given; without which, it would be im-
pofilble to make every particular underftood here.
