course of the dealings of those two countries with one another, but will be influenced by that of the dealings of England with those other places. England may be obliged to send out every year money to Holland, though its annual exports to that country may exceed very much the annual value of its imports from thence; and though what is called the balance of trade may be very much in favour of England.
In the way, besides, in which the par of exchange has hitherto been computed, the ordinary course of exchange can afford no sufficient indication that the ordinary state of debt and credit is in favour of that country which seems to have, or which is supposed to have, the ordinary course of exchange in its favour: or, in other words, the real exchange may be, and, in fact, often is so very different from the computed one, that from the course of the latter, no certain conclusion can, upon many occasions, be drawn concerning that of the former.
When for a sum of money paid in England, containing, according to the standard of the English mint, a certain number of ounces of pure silver, you receive a bill for a sum of money to be paid in France, containing, according to the standard of the French mint, an equal number of ounces of pure silver, exchange is said to be at par between England and France. When you pay more, you are supposed to give a premium, and exchange is said to be against England, and in favour of France. When you pay less, you are supposed to get a premium, and exchange is said to be against France, and in favour of England.
But, first, we cannot always judge of the value of the current money of different countries by the standard of their respective mints. In some it is more, in others it is less worn, clipt, and otherwise degenerated from that standard. But the value of the current coin of every country, compared with that of any other country, is in proportion not to the quantity of pure silver which it ought to contain, but to that which it actually does contain. Before the reformation of the silver coin in king William’s time,
