![Lot 219 [Isaac Newton] Sketch of a](https://cdn.rrauction.com/auction/731/3505322_1.jpg)
Drawing in pen, ink, and grey wash, showing a "Manubrium or Winch," squirting water via a hose from a bucket, accomplished on an off-white 7 x 7.25 sheet. The handwriting is untraced, but this is evidently an item related to the activities of the secretaries of the Royal Society in handling the business of the Philosophical Transactions, apparently a drawing for a figure in that publication. Possibly communicated by Robert Hooke to Isaac Newton. In fine condition.
Provenance: Item (iii) from auction lot 391, source untraced: "Album containing a collection of papers by Robert Hooke and others, some evidently deriving from the papers of Sir Isaac Newton."
