Rh of gold circulation can make up for its quantity, or the presence of gold in the sphere of circulation is determined not only by its presence as an equivalent of a commodity side by side with it, but also by its participation in the movement of metamorphoses of commodities. The rapidity of the circulation of money, however, can serve as a substitute for its quantity only to a limited extent, since at any given moment an endless number of isolated purchases and sales takes places in different localities.

If the total price of the commodities in circulation rises, but in a smaller ratio than the increase in the rapidity of circulation of money, the volume of the circulating medium will diminish. If on the contrary the rapidity of circulation decreases in a greater ratio than the total price of the commodities in circulation, the volume of currency will increase. An increasing volume of currency combined with a general fall of prices or a diminishing volume of currency in connection with a general rise of prices is one of the best known phenomena in the history of prices. But the consideration of the causes which bring about a simultaneous rise in the level of prices and a still greater rise in the rate of velocity of circulation of money, or the opposite phenomenon, falls outside of the sphere of simple circulation. By way of illustration, it may be mentioned that in periods of prevailing credit, the rapidity of circulation of money grows
