The alteration in the limit of height of walls from 80 feet to 76 feet has been made partly because the height of such walls is now measured from the level of the adjacent foot-path instead of as formerly from the top of the footings, and partly to accord with the provisions of section 185 sub-section (5) of the same Ordinance.
