Abstract
ONE of the main objects of this pamphlet is to show how, by the use of the Chain Rule, the principles and practice of foreign exchanges can be brought down to the understanding of pupils of secondary and continuation schools. The author's purpose is “to prove by very simple arithmetical formula (sic) (1) that if the world possessed but one substance as its measure of value and equivalent in exchange, the world's interchanges of things could be effected on the conditions of barter.
