srom 45 deg. to 70 cleg, it may then be concluded, that every part of architectural decoration
susceptible of height will appear too low, if viewed under 20 deg. and too elevated if the visual
ray exceeds 70 deg.
Having coniidered the niost convenient situation sor viewing the high parts of a building, let
us osser the proper point to place the spectator, that he may see to the bell: advantage the whole
■ range of any considerable front of what extent soever ; this disiance is the summit os an equila-
teral triangle, die base of which is the sront in question.
When a building extends five or six hundred seet, the depth is not considered as a nccessarv
proportion. The extent of length mutt be divided into several distinct breakings, as the square
of its height, square and half, ccc. without which, no such design can ever appear beautiful,
each raust corrrespond with the whole, and yet be independently agreeable: but to examine
the correctness of the particular members, and the neatness and spirit of the ornaments, we mast
approach near enough to observe the minutest divisions.
