This 1971 book reviews and criticises the widely accepted hypothesis that the decline of the inland bill of exchange in Britain in the nineteenth century was largely due to the process of bank amalgamation, which linked bank branches in areas of excess demand for money with branches having surplus funds. Dr Nishimura argues that the introduction of the telegraph and steamship in the last quarter of the nineteenth century, by making both supply and demand more certain, relieved the merchant of the necessity to hold large stocks of goods in anticipation of orders. This book will be useful for other researchers in this field.
