Nota ad pag: 468 Newtoni, May 1694
Gregory tries to work out how Newton's lemma 1 to book 3 in the Principia derives the ratio of forces acting on the earth and thence the precession of the equinoxes. He wonders if Newton, who in the interest of brevity disliked showing his work, knows a shorter way to do this.
