not for this greater exportation of silver.

But the ordinary proportion between the respective values of two commodities is not necessarily the same as that between the quantities of them which are commonly in the market. The price of an ox, reckoned at ten guineas, is about threescore times the price of a lamb, reckoned at 3s. 6d. It would be absurd, however, to infer from thence that there are commonly in the market threescore lambs for one ox: and it would be just as absurd to infer, because an ounce of gold will commonly purchase from fourteen to fifteen ounces of silver, that there are commonly in the market only fourteen or fifteen ounces of silver for one ounce of gold.
