of Carbonic acid gas, which however though partially successful was afterwards abandoned. "But the great work by which his name will be transmitted to posterity is the Thames Tunnel which, though almost a complete failure as a commercial transaction is nevertheless a wondrous monument of engineering skill and enterprise. It was commenced in March, 1825, and opened to the public in 1843, after a multitude of obstacles and disasters." He held extensive premises at Battersea on the site now occupied by the Citizen Steam-boat Company, where his celebrated saw and veneer mills were burned down about the year 1814. He was elected a Fellow of the Royal Society in 1814; was appointed Vice-President in 1832. He was Knighted in 1840. Died Dec. 1849, in his eighty first year, universally respected. Sir Richard Phillips, who had an opportunity of inspecting Brunel's machinery at Battersea, eulogizes his fame and speaks of his merits and scientific genius thus:--"A few yards from the toll-gate of the Bridge on the western side of the road stand the workshops of that eminent, modest, and persevering mechanic Mr. Brunel, a gentleman of the rarest genius who has effected as much for the mechanic arts as any man of his time. The wonderful apparatus in the Dockyard at Portsmouth with which he sets blocks for the navy, with a precision and expedition that astonish every beholder, secures him a monument of fame and eclipses all rivalry." At Battersea Works Sir Richard witnessed four circular saws, two of them 18-ft. in diameter and two of them 9-ft. in diameter, besides other circular saws much smaller used for the purpose of separating veneers. He saw planks of mahogany and rosewood sawn into veneers the 16th of an inch thick. By the power that turned those tremendous saws he beheld a large sheet of veneer 10-ft. long by 2-ft. broad separated in ten minutes "so even and so uniform that it appeared more like a perfect work of nature than one of human art." In another building Sir Richard was shown Mr. Brunel's manufactory for shoes, where the labour was sub-divided so that each shoe passed by aid of machinery through twenty-five hands complete from the hide as supplied by the currier. By this means a hundred pairs of strong and well-finished shoes were made per day. He remarks, "each man performs but one step in the process, which implies no knowledge of what is done by those who go before or follow him. The persons employed are not shoemakers, but wounded soldiers, who are able to learn their respective duties in a few hours. The contract at which these shoes are delivered to Government is 6s. 6d. per pair, being at least 2s. less than were paid previously for an unequalled and cobbled article." The shoes thus made for the Army were tried for two years but afterwards abandoned from economical views.
