Note 6 — Chapter V · ON THE DEFINITION AND APPLICATION OF TERMS BY MR. RICARDO.
Reading edition
Polit. Econ. c. xx. p. 326. 3rd edit.—It may be remarked, by the way, that Mr. Ricardo here uses labour as a measure of value in the sense in which I think it ought always to be used, and not according to his own theory. He measures the exchangeable value of the plate and velvet, not by the quantity of labour worked up in them, but by the quantity they will command or employ.
