Dear Marc

The source is 'Passages from the Life of a Philosopher', Babbage's autobiographical excursion. I am away from my sources in London at this time so can't check the page number but it is, as I recall, in the chapter on the Analytical Engine about where CB writes about tic-tac-toe arcade machines as another reference to funding the construction of the Analytical Engine. The references CB makes to novel writing appear in the nature of a passing musing rather than conscientious intention - but who knows. The intention may have been real and the reference only, casual.

Best wishes Doron
