I shall be very glad if I find that by this translation I have in any way contributed to increase the circulation of your remarks in this country. The subject is one of considerable interest, and I hope that you will, at no very distant period, give us some further observations, and let us know how far your first impressions have been then influenced by events which may have occurred subsequently to the present time.

REMARKS ON THE PRODUCTION OF THE PRECIOUS METALS, &c. From the commencement of the 19th century, gold appears to have been always esteemed in Europe above the price at which it has been legally fixed in relation to silver; the commercial value of the metal has remained on an average about 1 per cent. above its legal value. In England alone gold circulates as money: in those countries which have maintained a double standard, gold, rarely coined, became immediately an article of merchandize, and disappeared from circulation. Gold regions were discovered without restoring the equilibrium of value between the two metals. Civilization, in its development from historical times, has but realized the legends of ancient fables. Gold, from its importance and constancy of value, appeared likely to remain for ever the symbol and the essential agent of wealth. In this regular course of the progress of the precious metals, a pause, or rather a deviation, appears to have occurred. Gold seems to be tottering in its monetary supremacy; the fortress appears to have succumbed in a paroxysm of alarm. Ten years ago, every one was frightened at the prospect of the depreciation of silver; during the last eighteen months, it is the diminution in the price of gold that has been alarming the public. Some countries, which, but a short time since, were but too anxious to attract and retain gold in circulation, even at great sacrifices, have already shown a feverish anxiety to banish it altogether.
