The Sixty-ninth FIGURE.
John James translation
The Plan of the Sixty-seventh Figure in Perspective, and third Preparation to the Seventy-first Figure.
The Artifice us’d in projecting the Perspective of this Plan, has been already shewn in the Forty-second Figure; namely, that for giving the greater Distance between the Parallels, the Ground-line is drawn much lower than its true Place; as is manifest on Inspection of the Figure.
