Note 44 — Chapter V
Reading edition
I am obliged to give these measures approximately, because, this front having been studied by the builder with unusual care, not one of its measures is the same as another; and the symmetries between the correspondent arches are obtained by changes in the depth of their mouldings and variations in their heights, far too complicated for me to enter into here; so that of the two arches stated as 19 ft. 8 in. in span, one is in reality 19 ft. 6½ in., the other 19 ft. 10 in., and of the two stated as 20 ft. 4 in., one is 20 ft. and the other 20 ft. 8 in.
