ITem, quod eadem ſolida baſes habentia altitudinibus; vel ſe-
cantibus æqualiter tangentibus inclinatis reciprocas, ſint æ-
qualia; & quæ ſunt æqualia, baſes habeant altitudinibus, vel ſe-
cantibus æqualiter tangentibus inclinatis reciprocas.

miparabolas, ex quibus in reuolutione generantur, habeant ean-
dem rationem.
