Book 1[edit]

 THE MOTION OF BODIES
 Of the method of first and last ratios of quantities, by the help whereof we demonstrate the propositions that follow [1]
 Of the invention of centripetal forces [2]
 Of the motion of bodies in eccentric Conic sections [3]
 Of the finding of elliptic, parabolic, and hyperbolic orbits, from the focus given [4]
 How the orbits are to be found when neither focus is given [5]
 How the motions are to be found in given orbits [6]
 Concerning the rectilinear ascent and descent of bodies [7]
 Of the invention of orbits wherein bodies will revolve, being acted upon by any sort of centripetal force [8]
 Of the motion of bodies in movable orbits; and of the motion of the apsides [9]
 Of the motion of bodies in given superficies; and of the reciprocal motion of funependulous bodies [10]
 Of the motions of bodies tending to each other with centripetal forces [11]
 Of the attractive forces of sphaerical bodies [12]
 Of the attractive forces of bodies which are not of a sphaerical figure [13]
 Of the motion of very small bodies when agitated by centripetal forces tending to the several parts of any very great body [14]
Book 2[edit]

 THE MOTION OF BODIES (In resisting mediums)
 Of the Motion of Bodies that are resisted in the ratio of the Velocity [15]
 Of the Motion of Bodies that are resisted in the duplicate ratio of their Velocities [16]
 Of the Motions of Bodies which are resisted partly in the ratio of the Velocities, and partly in the duplicate of the same ratio [17]
 Of the circular motion of bodies in resisting mediums [18]
 Of the density and compression of fluids; and of Hydrostatics [19]
 Of the motion and resistance of funependulous bodies [20]
 Of the motion of fluids and the resistance made to projected bodies [21]
 Of motion propagated thro' fluids [22]
 Of the circular motion of fluids [23]
Book 3[edit]

 OF THE SYSTEM OF THE WORLD
