Originally published in 1936, this book discusses the post-War reconstruction of the monetary system. It examines the American use of silver and changes to China''s currency system and asks whether a combination of gold and silver would not be a better solution than a pure Gold Standard. The book discusses to what extent it is possible to unite the advantages of an orthodox metallic standard with the greater elasticity which was required. Using geometry, the author gives a more complete picture of the relationships involved in Symmetallism and a theoretical account of the symmetallic Bullion Standard.
