PREFATORY NOTE

applications of algebraic symbols and geometrical diagrams
to economic problems are presented in an appendix. Those
to whom these forms of expression tend rather to confuse
than to clarify the reasoning which they embody, may thus
readily spare themselves this confusion; while those to
whom these symbols are familiar and helpful will not be
deprived of the aid to precision of conception and of
argument which can hardly be afforded in equal degree by
any other means.
Readers who desire to pursue something more than an
introductory course of economic study will find a few
references to the more accessible works in the English
language in the table of contents.
