Note 22 — Chapter II
Reading edition
It is worth noticing that the courses of stone in a mosque or house are always 13 or 14 inches high, and are hardly ever subdivided. The windows, doors, and ornament are therefore regulated by the courses, and are four or six courses, or whatever the number, and not four-and-a-half, &c. It is thus easy to calculate the height of a building of stone by counting its courses.
