Description
Diagrams in a copy of one of Newton's earliest drafts (now presumed lost) 'on motion' (1684), which became Book 1 of Principia mathematica philosophiae naturalis (1687).
A diagram for problem 4: supposing that the centripetal force be reciprocally proportional to the square of the distance from its centre, and with the quantity of that force known, there is required the ellipse which a body shall describe when released from a given position with a given speed following a given straight line. Compare Principia (1687), book 1, proposition 17, problem 9.
This is copied from RBO/6/226.

Object history
At the meeting of the Royal Society on 10 December 1684, 'Mr. Halley gave an account, that he had lately seen Mr. Newton at Cambridge, who had shewed him a curious treatise, De Motu; which upon Mr. Halley's desire, was, he said, promised to be sent to the Society to be entered upon their register. Mr. Halley was desired to put Mr. Newton in mind of his promise for the securing his invention to himself till such time as he could be at leisure to publish it. Mr. Paget was desired to join with Mr. Halley' (Birch 4:347).
This is a copy of the tract sent via Edward Paget to Halley, which contained Newton's demonstration that an elliptical orbit entails an inverse-square force to one focus. From these insights, Newton went on to develop his Principia mathematica philosophiae naturalis. The original draft is presumed lost.
