Henry Prevost Babbage was the youngest son of Charles Babbage and after his father's death took possession of all his father's materials relating to the calculating engines. Here he reports that he was able to assemble the arithmetic unit of the analytical engine to the point where it could do simple calculations. He also explains his reasons for melting down the remaining portions of his father's Difference Engine.

The report by the committee in the third paper concludes by "we are ... of the opinion that [Babbage's engine] is not more than a theoretical possibility; that is to say, we do not consider it a certainty that it could be constructed and put together so as to run smoothly and correctly, and to do the work expected of it. We cannot advise the British Association to take any steps, either by way of recommendation or otherwise, to procure the construction of Mr. Babbage's Analytical Engine..." The second paper also includes George Francis Fitzgerald's Presidential Address to Section A (Mathematical and physical sciences), pp.557-562, [T&W F76] and a review of Henry Selby Hele-Shaw's "A new sphere planimeter", pp.584-585, [T&W H96].
