On the whole, then, it appears that the demand for gold and silver, as articles of commerce, is likely to exceed the demand for the precious metals solely for use as money. This is a new point; and we must not lose sight of it in endeavouring to appreciate the effect which an increase or diminution in the production of the precious metals may have, both on their price and on their relative value. Without noting the variations which have occurred from one century to another, in the production and in the importation of gold and silver, in order to recapitulate the quantities of the precious metals which America has poured into the European markets in 318 years, from the discovery of Hispaniola to the revolution in Mexico, M. de Humboldt considers the production of gold to have been [7]2,381,600 kilogrammes, and that of silver [8]110,362,222 kilogrammes: making a total value of about [9]32 “milliards” of francs: the weight of gold imported represents about ¹⁄₄₇th of that of silver. It does not appear probable, that the produce of gold in other parts during these three centuries has materially altered these proportions. Admitting that when first the Mexican revolution retarded the working of their silver mines, the amount of coined money throughout Europe represented a value of [10]8 “milliards” of francs, of which [11]6 “milliards” were in silver, and [12]2 “milliards” in gold, the relative quantity in weight would still have been as 47 to 1; and yet the relative monied value, thirty years since, varied in Europe between 1 to 14½, and 1 to 15¾. Thus, in the value of the precious metals, the difference was three times less than in their weight. Nothing is more difficult in matters relating to money than to present statistics which may be considered as an approximation to truth. It would appear that as gold and silver are used as the denominators of value, generally, throughout the world, all the phenomena connected with their production and circulation ought to be noted with the greatest precision: they ought to be the points to which the attention of statisticians should be “_par excellence_” directed. What can be more important, in an economical point of view, than to establish a regular scale, indicating the rapidity of every movement connected with the subject, and acting as a gauge of its extent?
