If you except corn and such other vegetables as are raised altogether by human industry, that all other sorts of rude produce, cattle, poultry, game of all kinds, the useful fossils and minerals of the earth, etc., naturally grow dearer as the society advances in wealth and improvement, I have endeavoured to show already. Though such commodities, therefore, come to exchange for a greater quantity of silver than before, it will not from thence follow that silver has become really cheaper, or will purchase less labour than before, but that such commodities have become really dearer, or will purchase more labour than before.

It is not their nominal price only, but their real price which rises in the progress of improvement. The rise of their nominal price is the effect, not of any degradation of the value of silver, but of the rise in their real price.
