Copy letter from Herbert Rix, to Mr Mills, Inspector of Meters, London County Council Meter Inspectors Office, St Anne Street, Westminster 'Sir, We have reason to think that our gas-meter registers enormously in excess of our actual consumption. I am directed to ask that it may be tested. I have communicated with the Gas Light & Coke Co, and they instruct me to apply to you. I am, yours truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 30 July 1891
