Catalogue Note

The first item is the first separate printing of the British government's reprint of Babbage's 1822 letter to Sir Humphry Davy which also appears in volume 15 of The House of Commons Sessional Papers, paginated 9-16. This separate printing also includes for the first time copies of accompanying letters from the Treasury and the Royal Society. The letter to Brewster describes the interesting developments occurring when the Difference Engine, rather than simply adding differences, was set to add multiples of differences.
