* Auzout’s meafure of the foot on the monument of 
M. Ebutius, is nearly equal to 973 London parts. 
Revillas makes this 972*, and the Capponian foot 
968^. 
The mean of thefe meafures of the Roman foot on 
the marbles, is nearly 969 thoufandth parts of the 
London foot. 
Philander, in his notes on Vitruvius (2), fays, the 
foot from a porphyry column, infcribed nOA. ©• 
exceeded the Coffutian foot by the ninth pait of an 
inch ; therefore it contained nearly 974 London parts. 
This column feems to have been a more authentic 
meafure of the Roman foot, than the figures on the 
monuments; fince the infcription fliews it was in- 
tended for fuch, whereas they were only reprefenta- 
tions of it. And notwithftanding the inlcnption was 
Greek, the foot mull have been Roman ; for Philan- 
der’s meafure of it exceeds the mean meafuie of thofe 
on the marbles, by lefs than the fixteenth part of a 
London inch, and is lefs than fome of the antient 
foot-rules, hereafter mentioned; whereas it wants 
above the third part of an inch to be equal to the 
Greek foot. It might, perhaps, be ufed by fome 
Greek mafon at Rome, to adjuft his workmens rules 
by ; for when the Romans began to be expenfive in 
their buildings, they had mod of their maions from 
Greece. And though this column is not now to be 
found, and the accuracy of Philander’s meafure of it 
may be doubted, it is ftill a proof, that, at one time 
or other, the meafure of the Roman foot was fenlibly 
greater than that on the monument of Coflutius.
