 His work and frequently updated books such as his "Practical Treatise on Banking" (1827) were eventually widely adopted to improve the British banking systems and laid the foundations of the modern publicly owned retail bank and Building Society movement.It was Gilbart who standardised the modern spelling of the word "cheque" in his book "Practical Treatise on Banking", and formalised this in subsequent legislation.Some claim that the spelling was derived from early notes issued by Goldsmiths of London.
