payment—being given, the total amount of money in circulation at a given time will be determined by the sum total of the prices of commodities to be realized, plus the total amount of payments falling due at the same time, minus the amount of payments balancing each other. The general law that the volume of money in circulation depends on the prices of commodities is not affected by this in the least, since the extent of the payments is itself determined by the prices stipulated in contracts. What is, however, strikingly demonstrated, is that even if the rapidity of circulation and the economy of payments be assumed to remain the same, the sum total of the prices of the commodities circulating in a given period of time, say one day, and the volume of money in circulation on the same day are by no means equal, because there is a large number of commodities in circulation whose prices have yet to be realized in money at a future date, and there is a quantity of money in circulation which constitutes the payment for commodities which have long gone out of circulation. The latter amount will depend on the sum of payments falling due on the same day although contracted for at entirely different periods.
We have seen that a change in the values of gold and silver does not affect their function as measures of value or money of account. But this change is of decisive importance for money as a hoard, since with the rise or fall of value of gold and silver, the total value of a gold or silver hoard will also rise or fall. Of still greater importance is the effect of this change on money as a means of payment. The payment takes
