As the
rate of wages is itself fluctuating, and as the prices paid and
quantities executed have been given only between certain limits,
it is not to be expected that this table can represent the cost
of each part of the work with the minutest accuracy, nor even
that it shall accord perfectly with the prices above given: but
it has been drawn up with some care, and will be quite sufficient
to serve as the basis of those reasonings which it is meant to
illustrate. A table nearly similar will be subjoined, which has
been deduced from a statement of M. Perronet, respecting the art
of pin-making in France, above seventy years ago.
