1. CLAY, HENRY . Economics for the General Reader. Macmillan . Page 164. A good short account of money from the standpoint of the economist.
2. EINZIG, PAUL . Primitive Money. Eyre & Spottiswoode, N.D. , 1949. Page 353 et. seq. Einzig is more cautious than Hingston Quiggin, and, though he reaches substantially the same conclusion, he draws attention to the many sources on which money can depend for its value: it is a wholesome corrective to any facile generalisation. I am inclined to think that the concept of the basic assumptions might throw light on a subject the complexity of which is better displayed by Einzig than by Hingston Quiggin.
