length of the race course?” and the answer
were, ‘ The convenience of the spectators, who
could not have seen the horses at a greater
distance ;’ or, ¢ The choice of the subscribers ;’
then it is plain, that by the word ‘determined,’
I was understood to mean ‘ determined objec-
tively,” in relation to the existence of the object;
in other words, what caused the race-course to
be this length rather than another length: but
if the answer were, ¢ An actual admeasurement,’
it would then be plain, that by the word ¢ de-
termined,” I had been understood to mean ¢ de-
termined subjectively,” i. e. in relation to our
knowledge ; what ascertained it*?”

The writer just quoted is wrong, however,
in supposing Mr. Ricardo to be free from am-

is astonishing to find the author of the Dia-
* London Magazine, Dec. 1823. p. 588: article en-
iitled ¢¢ Measure of Value.”
