Note 1 — Chapter XV
Henry Yule translation
The Encyc. Britann., article “Money,” gives the livre tournois of this period as 18.17 francs. A French paper in Notes and Queries (4th S. IV. 485) gives it under St. Lewis and Philip III. as equivalent to 18.24 fr., and under Philip IV. to 17.95. And lastly, experiment at the British Museum, made by the kind intervention of my friend, Mr. E. Thomas, F.R.S., gave the weights of the sols of St. Lewis (1226–1270) and Philip IV. (1285–1314) respectively as 63 grains and 61½ grains of remarkably pure silver. These trials would give the livres (20 sols) as equivalent to 18.14 fr. and 17.70 fr. respectively.
