Mr. Malthus, having acknowledged this principle, cannot, I think, consistently maintain that the whole money value of all the commodities in the country must sink exactly in proportion to the fall in the price of corn. If the corn consumed in the country were of the value of ten millions per annum, and the manufactured and foreign commodities consumed were of the value of twenty millions, making altogether thirty millions, it would not be admissible to infer that the annual expenditure was reduced to 15 millions, because corn had fallen 50 per cent., or from 10 to 5 millions.
The value of the raw produce which entered into the composition of these manufactures might not, for example, exceed 20 per cent. of their whole value, and, therefore, the fall in the value of manufactured commodities, instead of being from 20 to 10 millions, would be only from 20 to 18 millions; and after the fall in the price of corn of 50 per cent., the whole amount of the annual expenditure, instead of falling from 30 to 25 millions, would fall from 30 to 23 millions.11
Instead of thus considering the effect of a fall in the value of raw produce; as Mr. Malthus was bound to do by his previous admission; he considers it as precisely the same thing with a rise of 100 per cent. in the value of money, and, therefore, argues as if all commodities would sink to half their former price.
"During the twenty years, beginning with 1794," he says, "and ending with 1813, the average price of British corn per quarter was about eighty-three
