this Book_.

FRENCH MONEY.

The LIVRE TOURNOIS of the period may be taken, on the mean of five
valuations cited in a footnote at p. 87 of vol. i., as equal in _modern
silver value_ to ... 18.04 _francs_.

Say English money ... 14_s._ 3.8_d._

The LIVRE PARISIS was worth one-fourth more than the _Tournois_,[1]
and therefore equivalent in silver value to ... 22.55 _francs_.

Say English money ... 17_s._ 10.8_d._

(Gold being then to silver in relative value about 12:1 instead of about
15:1 as now, one-fourth has to be added to the values based on silver in
equations with the gold coin of the period, and one-fifth to be deducted
in values based on gold value. By oversight, in vol. i. p. 87, I took 16:1
as the present gold value, and so exaggerated the value of the livre
Tournois as compared with gold.)

M. Natalis de Wailly, in his recent fine edition of Joinville, determines
the valuation of these _livres_, in the reign of St. Lewis, by taking
a mean between a value calculated on the present value of silver, and a
value calculated on the present value of gold,[2] and his result is:
