§ Mr. Lubbock
asked the Chancellor of the Exchequer what estimate he has made of the cost and benefits of changing to a demical currency system.
§ Mr. Maurice Macmillan
An estimate of the cost was given in the Halsbury Report. The Halsbury Committee described the benefits as "incapable of measurement", but they would clearly be appreciable, although diffused throughout the economy and spread over a considerable period of time.
