Finally, in what follows, it will be the more legitimate to neglect the absolute variations which affect the value of the monetary metals, as we do not have numerical applications directly in view. If the theory were sufficiently developed, and the data sufficiently accurate, it would be easy to go from the value of an article in terms of a fictitious and invariable modulus, to its monetary value. If the value of an article, in terms of this fictitious modulus, was ${\displaystyle p}$, at a time when that of the monetary metal was ${\displaystyle \pi }$, and if at another time these quantities had taken other values, ${\displaystyle p^{\prime }}$ and ${\displaystyle \pi ^{\prime }}$, it is evident that the monetary value of the article would have varied in the ratio of
${\displaystyle {\frac {p}{\pi }}{\mbox{ to }}{\frac {p^{\prime }}{\pi ^{\prime }}}.}$
