An Inquiry into the Nature and Causes of the Wealth of Nations. Adam Smith

to Mr. Meggens {Postscript to the Universal Merchant p. 15 and 16. This postscript was not printed till 1756, three years after the publication of the book, which has never had a second edition. The postscript is, therefore, to be found in few copies; it corrects several errors in the book.}, the annual importation of the precious metals into Spain, at an average of six years, viz. from 1748 to 1753, both inclusive, and into Portugal, at an average of seven years, viz. from 1747 to 1753, both inclusive, amounted in silver to 1,101,107 pounds weight, and in gold to 49,940 pounds weight. The silver, at sixty two shillings the pound troy, amounts to £ 3,413,431:10s. sterling. The gold, at forty-four guineas and a half the pound troy, amounts to £ 2,333,446:14s. sterling. Both together amount to £ 5,746,878:4s. sterling. The account of what was imported under register, he assures us, is exact. He gives us the detail of the particular places from which the gold and silver were brought, and of the particular quantity of each metal, which, according to the register, each of them afforded. He makes an allowance, too, for the quantity of each metal which, he supposes, may have been smuggled. The great experience of this judicious merchant renders his opinion of considerable weight.

      According to the eloquent, and sometimes well-informed, author of the Philosophical and Political History of the Establishment of the Europeans in the two Indies, the annual importation of registered gold and silver into Spain, at an average of eleven years, viz. from 1754 to 1764, both inclusive, amounted to 13,984,185⅗ piastres of ten reals. On account of what may have been smuggled, however, the whole annual importation, he supposes, may have amounted to seventeen millions of piastres, which, at 4s. 6d. the piastre, is equal to £ 3,825,000 sterling. He gives the detail, too, of the particular places from which the gold and silver were brought, and of the particular quantities of each metal, which according to the register, each of them afforded. He informs us, too, that if we were to judge of the quantity of gold annually imported from the Brazils to Lisbon, by the amount of the tax paid to the king of Portugal, which it seems, is one-fifth of the standard metal, we might value it at eighteen millions of cruzadoes, or forty-five millions of French livres, equal to about twenty millions sterling. On account of what may have been smuggled, however, we may safely, he says, add to this sum an eighth more, or £ 250,000 sterling, so that the whole will amount to £ 2,250,000 sterling. According to this account, therefore, the whole annual importation of the precious metals into both Spain and Portugal, mounts to about £ 6,075,000 sterling.
