foot from the congius to contain about yo. 1*0.1- 
don parts. 
Greaves took likewife another meafure of inis, 
congius, by the cube of his Cofiutian foot, which 
he found to contain 7 congii, and about an half, of 
millet (5). Now, the quadrantai fhould contain 8> 
hence the fide of the quadrantai to this congius will 
contain 988 parts of the iron ftandard: for 988 is to 
967 (Greaves’s meafure of the Coffutian foot) in the 
fubtriplicate proportion of 8 to J{. But this is a greater 
meafure than even that of Villalpandus, and was pro- 
bably owing to an erroneous cube of the Coffutian 
foot ; for the joiners at Rome might be as bad work- 
men as the fcalemakers ; and Greaves fays, he could 
not get a ballance there, fit to examine the congius 
by weight ( 6 ). 
Monf. Aftruc, in his Natural Hiftory of Langue- 
doc, fays, he had caufed the diftance between the 
ninth and tenth mile-fiones on the road from Nifmes 
to Beaucaire to be meafured, and that it was found 
to be 7 54 Paris toifes. They were both fet up by 
Tiberius, and the road lies in a ftrait line between 
them. This meafure gives a Roman foot of 96 4 
London parts. He does not fay he took this meafure 
himfelf (7), nor has he given any account how it 
was taken. Perhaps by a provincial meafure, and

Bis expreffion is, ‘ c J’ai fait mefurer la diftance de 1 un a 1 autre - , 
et elle s’eft trouvee de 754 toifes de Paris.” Where he fpeaks of 
the Marquis Maffsei, he fays, “ II amefure ;” but, in the fame 
paragraph, fpeaking of himfelf, he again fays, “ J’ai fait mefurer.”'
