than gold. Though both the gold and silver mines of America exceeded in fertility all those which had ever been known before, the fertility of the silver mines had, it seems, been proportionally still greater than that of the gold ones.
The great quantities of silver carried annually from Europe to India, have, in some of the English settlements, gradually reduced the value of that metal in proportion to gold. In the mint of Calcutta, an ounce of fine gold is supposed to be worth fifteen ounces of fine silver, in the same manner as in Europe. It is in the mint, perhaps, rated too high for the value which it bears in the market of Bengal. In China, the proportion of gold to silver still continues as one to ten, or one to twelve. In Japan, it is said to be as one to eight.
The proportion between the quantities of gold and silver annually imported into Europe, according to Mr Meggens’ account, is as one to twenty-two nearly; that is, for one ounce of gold there are imported a little more than twenty-two ounces of silver. The great quantity of silver sent annually to the East Indies reduces, he supposes, the quantities of those metals which remain in Europe to the proportion of one to fourteen or fifteen, the proportion of their values. The proportion between their values, he seems to think, must necessarily be the same as that between their quantities, and would therefore be as one to twenty-two, were it 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 three score 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 three score lambs for one ox; and it would be just as absurd to infer, because an ounce of gold will commonly purchase from fourteen or fifteen ounces of silver, that there are commonly in the market only fourteen or fifteen ounces of silver for one ounce of gold.
