Curious textual similarities?

Bradshaw’s Hand Book to London 1862 says of Seven Dials on p.120: ‘..The angular direction of each street renders the spot rather embarrassing to a pedestrian who crosses this maze of buildings unexpectedly, and frequently causes him to diverge from the road that would lead him to his destination..’.

Walter Thornbury, Old and New London, 1878, Vol .3, Chap.XXVI, on this site says of Seven Dials: ‘..The angular direction of each street renders the spot rather embarrassing to a pedestrian who crosses this maze of buildings unexpectedly, and frequently causes him to diverge from the road that would lead him to his destination..’.

Mr Bradshaw’s work was clearly respected and well-used.

Where and how, I have often wondered, did Mr Bradshaw source his information without access to the internet?
