I annex a copy of the correspondence which took place at that time, and which your Lordship will observe was laid before Parliament.
The Committee of the Royal Society, to which the subject was referred, reported generally that the invention was one "fully adequate to the attainment of the objects proposed by the inventor, and that they considered Mr. Babbage as highly deserving of public encouragement in the prosecution of his arduous undertaking."—Report of Royal Society, 1st May, 1823.

And in a subsequent and more detailed Report, which I annex also, they state:—
"The Committee have no intention of entering into any consideration of the abstract mathematical principle on which the practicability of such a machine as Mr. Babbage's relies, nor of its public utility when completed. They consider the former as not only sufficiently clear in itself, but as already admitted and acted on by the Council in their former proceedings. The latter they regard as obvious to every one who considers the immense advantage of accurate numerical Tables in all matters of calculation, especially in those which relate to Astronomy and Navigation, and the great variety and extent of those which it is the object and within the compass of Mr. Babbage's Engine to calculate and print with perfect accuracy."—Report of Committee of Royal Society, 12th Feb., 1829.
Upon the first of these Reports, the Government determined to construct the machine, under my personal super-
