Conte Giordano Riccati Di Treviso, Con due Lettere del medesimo Signor Conte Riccati all’ Autore. Bassano MDCCLXXXIV.
Collation: A8-B8; [Figure, 1].

Printer is (Remondini), Bassano, 1784. 1 table refolded f.t with 9 figures from copper plate. In this dissertation, Franceschinis takes cue from a theorem contained a volume of the works dell’ Abbot Paul Frisi and in order to refute it, demonstrates with a rigorous method that the force expressed from the tension of a rope is proportional to the points of the angles constituted from two sides of the same rope.

Very nice but disbound and several pages loose but complete. Toned and lightly stained front and back. A very nice mathematical document.
