1876 Obituary 
MR. WILLIAM CHADWELL MYLNE, the second son of the late Mr. W. C. Mylne, M. Inst. C.E., F.R.S., was born at the New River Head, Clerkenwell, on the 7th of February, 1821.
He entered his father’s office at an early age, and in November 1845 was appointed River Surveyor in connection with his father, the Engineer-in-Chief to the New River Company, who had himself succeeded, in 1811, Robert Mylne, the grandfather of the subject of the present notice, Mr. Mylne, for three years previous to his appointment, was an assistant in the New River Company’s works, and he continued the duties of River Surveyor until the spring of 1875, when, from ill-health, he resigned this office and retired to Bath.
Mr. Mylne’s professional occupations were almost wholly confined to the service of the New River Company, whose extensive concerns necessarily absorbed almost his entire attention. At various times, however, he was engaged in other undertakings, and his last independent professional work was the successful construction, in 1869, of a deep shaft into the chalk at Coldbath Fields House of Correction, Clerkenwell, for a supply of water to that establishment.
Mr. W. C. Mylne was elected an Associate of the Institution of Civil Engineers on the 13th of April, 1847, and he died at Bath on the 14th of March, 1876, aged fifty-five.
