Supposing upon the Wall B C, [Tab. 2. Fig. 10.] I Paint the Figure of a House, to appear at a Miles distance; and this done, I discover a real House, actually removed to that distance: these two Houses, I dispose so by the side of each other, as that the Sections of the Line A C, made by each Piramid of visual Rays, be equal; and yet after all, viewing these two Houses with both Eyes, they neither appear equally big, nor equally distant.
