The computed exchange has generally been in favor of London with Lisbon, Antwerp, Leghorn, and, if you except France, I believe, with most other parts of Europe that pay in common currency; and it is not improbable that the real exchange was so too.
Digression Concerning Banks of Deposit, Particularly Concerning that of Amsterdam
The currency of a great State, such as France or England, generally consists almost entirely of its own coin. Should this currency, therefore, be at any time worn, clipped, or otherwise degraded below its standard value, the State by a reformation of its coin can effectually re-establish its currency. But the currency of a small State, such as Genoa or Hamburg, can seldom consist altogether in its own coin, but must be made up, in a great measure, of the coins of all the neighboring States with which its
