[1] A complete list of the names of all the competitors, together with those selected by the Committee, will be found in the Appendix; also a description and views of the two designs specially referred to. [2] This "memorandum" will be found in the Appendix. [3] The figures quoted are not quite correct, as will be seen hereafter. [4] The surface covered by the Basilica of St. Peter's at Rome amounts to 223,900 square feet, the Cathedral at Milan occupies 124,100, and St. Paul's, London, 114,900 square feet. [5] It is perhaps necessary to mention here, that the leakage of the roof which was at first much complained of was owing to incomplete construction, and not to any defect in the principle, or in the manner in which it has been carried out. [6] About three hundred planks were passed through the machine in a working-day of ten hours, allowing the necessary stoppages for sharpening the cutters; and if only three widths of sash-bar were produced out of each blank, the quantity finished per diem would amount to about two miles and three quarters. This machinery, as well as that for grooving and moulding the ridges, was worked at the Phoenix Saw-mills, Cumberland-basin, Regent's Park, belonging to Mr. Birch. [7] A This piece of machinery is only novel in its application, as it is similar to that used by brush-makers for drilling a number of small holes in close and regular arrangement.
