contingencies. The supply of money, in short, is all the money in circulation at the time.
The demand for money, again, consists of all the goods offered for sale. Every seller of goods is a buyer of money, and the goods he brings with him constitute his demand. The demand for money differs from the demand for other things in this, that it is limited only by the means of the purchaser. The demand for other things is for so much and no more; but there is always a demand for as much money as can be got. Persons may indeed refuse to sell, and withdraw their goods from the market, if they cannot get for them what they consider a sufficient price.

It is always a sine quâ non with a dealer to dispose of his goods.
As the whole of the goods in the market compose the demand for money, so the whole of the money constitutes the demand for goods. The money and the goods are seeking each other for the purpose of being exchanged. They are reciprocally supply and demand to one another. It is indifferent whether, in characterizing the phenomena, we speak of the demand and supply of goods, or the supply and the demand of money. They are equivalent expressions.
We shall proceed to illustrate this proposition more fully. And in doing this, the reader will remark a great difference between the class of questions which now occupy us, and those which we previously had under discussion respecting Values. In considering Value, we were only concerned with causes which acted upon particular commodities apart from the rest. Causes which affect all commodities alike, do not act upon values. But in considering the relation between goods and money, it is with the causes that operate upon all goods whatever, that we are specially concerned. We are
