The Forty-ninth FIGURE.

The Elevation of the Ionick Design in Perspective.

This Plate containing the Perspective of the foregoing Upright, is drawn by the Method laid down in the Forty-second Figure; to wit, from the Plan B of the Forty-seventh Figure, Parallels to the Ground-line CD are prolong’d to the Visual OM; and thence are continu’d Parallels to the Perpendicular EC. These being transferr’d into this Figure, are intersected by the visual Lines that proceed from AB, which contains the Heights of this Ionick Composition, agreeable to the foregoing Figure, and the Rules deliver’d by Vignola. Now there is no Point in any Member of this Upright, but may be found by the Intersection which the visual Line from AB makes with its respective Perpendicular.
