Transcription
Hence ariseth (in the transverse lines) for the first movement 1, for the second 1 + 1, for the third 1 + 1+ 1, and so forth, in Arithmetical progression: As are the Ordinates in a Triangle, at equal distance.
And such are the continual increments of the Diameter or of the Ordinates in the exterior Parabola, answering to the interior ordinates, or segments of the Tangent equally increasing. As is known, and commonly admitted.
