fractions of the digit in the divil'ors, by which means 
any mealure of the foot might be derived from any 
building. I , . 
A mean from the feven firft horizontal meafuies 
gives a Roman foot of 964,3 P ar * s * A mean from 
the uprights one of 964,4. *'■ 
But the depth of the folid, and the widths of the 
entrances are moll to be depended on,, and thefe give 
a foot of 964! London parts ; which will be found 
to be the greatefl meafure this building will anfwer 
to by probable divifors. 
For though the extent of the front, or the width 
of the middle entrance, mult probably have been the 
prime meafure in a building of this kind; yet no 
part feems more likely to confift of fome number at 
whole feet (or at leaft whole palms) than the depth 
of the folid; fince there appears no. reafon why the 
arehitea lhould ufe odd digits in the meafure of it. 
Now if we fuppofe the extent of the front to have 
been 78-? Roman feet, they will contain 9 70 parts 
each ; but to make the depth agree with this mea- 
fure, it mull have been 23! fuch feet, which does 
not feetn probable, for the reafon above-mentioned. 
The middle entrance mull then have been 22 Y > in- 
ftead of 23 whole feet, and the extent on each fide 
274#, inllead of 28. And there will not be one 
whole meafure in the plan of this building, w ic 
is improbable. Neither do thefe broken mealures 
ferve for the fubdivifion of the fides better, or even 
fo well as the whole ones. 
The lhafts of the columns are fo nearly 1 6 modules,
