In one MS. I read (l. ii. c. 4, p. 409) perfumante quatro solli, in another, quatro florini, an important variety, since the florin was worth ten Roman solidi (Muratori, dissert. xxviii). The former reading would give us a population of 25,000, the latter of 250,000 families; and I much fear, that the former is more consistent with the decay of Rome and her territory.
