Woollen or linen cloth are not the regulating commodities by which the real value of all other commodities must be finally measured and determined; corn is. The real value of every other commodity is finally measured and determined by the proportion which its average money price bears to the average money price of corn. The real value of corn does not vary with those variations in its average money price, which sometimes occur from one century to another; it is the real value of silver which varies with them.
