The Reducing into Perspective the Plan of the Fortieth Figure, and the Upright of the Forty-first Figure, would become very confus’d, through the great Obliquity of the Rays: We have therefore remedy’d the Inconveniences of both, by the Methods explain’d in the Tenth and Eleventh Figures. And this Plate contains in little, what is more at large describ’d in Parts, as well in this, as the four subsequent Figures.
Fig. xliii.
FIGURA Quadragesimatertia.
Contractio vestigii figuræ quadragesimæ.
Linea plani multò remotior est à lineâ horizontali in hoc schemate, quàm in præcedenti. Ideo istud vestigium vacat omni confusione. Cætera patent ex iis quae sæpiùs dicta sunt, & ex figuræ hujus inspectione. Oportet autem, rectas parallelas ad lineam plani, prolongari usque ad visualem TO, (quæ cadit extra paginam) ut adminiculo parallelarum, fiat elevatio longitudinis nostri ædificii, de quâ dicemus figurâ quadragesimaquartâ.
