The above comparative measurements are given as being of the contemporary types of English and French cathedrals, being nearly approximate to each other as to the date of their erection and measurements. The figures themselves are transcribed from a little-known but thoroughly conscientious work by G. D. Whittington, entitled "Contributions to an Ecclesiastical Survey of France."
