NOTE.--The most important contributions to the theory of
consumption have been made by S. N. Patten in his numerous
writings, among them: _The Consumption of Wealth_ (1889);
_Theory of Dynamic Economics_ (1892); _The Theory of
Prosperity_ (1902). A number of the ideas are well
restated in more simple terms by E. T. Devine in
_Economics_, especially pp. 375-396, and 73-111 (applies to
chapter 41).
