By the death of Mrs. Bailey-Denton, widow of the eminent civil engineer, which occurred on the 4th inst. at Tunbridge Wells, in the eighty-third year of her age, another link connecting the present generation with the construction of our railways is severed. Mrs. Bailey-Denton assisted her husband in his surveys connected with the London and South Western Railway, the Midland Railway, and the Great Northern Railway, and celebrated her golden wedding in 1892.
