NOTE ON BOOKS 
Those who desire to make a further study of Political 
Economy are advised to peruse next some comprehensive 
work of an intermediate size. Works of this kind are 
numerous. The following have appeared in England :— 
Flux, Economic Principles ; Nicholson, Elements of 
Political Economy ; and my own Outlines of Political 
Economy. The following have appeared in the United 
States :—Bullock, Introduction to the Study of Economics ; 
Ely, Outlines of Economics; Fetter, Principles of Economics; 
Hadley, Economics ; Seagar, Introduction to Economics ; 
Seligman, Principles of Economics ; and Walker, Political 
Economy. In addition there is a book by Gide on Political 
Economy which has been translated from the French into 
English. 
After reading one of these volumes the student who 
aims at thoroughness should work through Marshall’s 
Principles of Economics, which is the authoritative treatise 
on theory, but does not cover money, foreign trade and 
public economics and finance. Large comprehensive 
treatises, which, however, are not substitutes for Marshall’s 
Principles in respect of the subjects included in the latter, 
have been penned by Nicholson (3 vols.), Taussig (2 vols.), 
and Pierson (in Dutch, of which only the first volume has 
been translated). Wicksteed’s Common Sense of Political 
Economy may also be mentioned, together with Panta- 
leoni’s Pure Economics (translated). 
Mathematicians who are interested in theory should 
carefully study the mathematical appendix to Marshall’s 
Principles, and consult in addition Edgeworth’s Mathe 
matical Psychics, the mathematical appendix to Flux’s
