The meafures of this elegant defign are fo incor- 
rectly executed, (hat I can make no ufe of them. 
The fronts of the two outer liftoff folids differ by a 
Paris inch and one third > the fide entrances by if ; 
the diftances of the columns from the pilafters (a 
meafure of little more than, 1 8 inches) differ an inch

befgodetz has given the meafure of no part of this 
budding , in feet, and inches, but the diameters of the 
columns j which he fays do not differ, from each other, 
as in many of the reft.

Thefe fhafts were probably intended for 16 mo- 
dules, and their meafure is more to be relied on than 
that of the diameters, both on account of its fize, 
and becaufe the correct execution of it was not only 
more ealy, but more neceffary. Therefore, though 
thefe meafures are too few, and too unequal to deter- 
mine the exaCt magnitude of the foot ufed in the con-
