Mathematical discourses concerning two new sciences : relating to mechanicks and local motion, in four dialogues. I. Of the resistance of solids against fraction. II. Of the cause of their coherence. III. Of local motion, viz. Equable, and naturally accelerate. IV. Of violent motion, or of projects / by Galileo Galilei ; with an appendix concerning the center of gravity of solid bodies ; done into English from the Italian by Tho. Weston, late master, and now published by John Weston, present master, of the Academy at Greenwich.
