Marx on the relationship between wages and prices

As we suppose that no change whatever has taken place either in the productive powers of labour, or in the amount of capital and labour employed, or in the value of the money wherein the values of products are estimated, but only a change in the rate of wages, how could that rise of wages affect the prices of commodities? Only by affecting the actual proportion between the demand for, and the supply of these commodities.
