### Ad pag: 221. Newtoni Nota, May 1694

Item

Identifier: Coll-33/Folio C [46]

Scope and Contents
Gregory's attempt to work out corollary 2 to Newton's proposition 91, from book 1 of the Principia, which compared the ratio of the attraction of a sphere to that of a spheroid, using the integration of the square root of a trinomial.

**Dates:**May 1694

### Ad Philosophiam Neutoni Nota, 15 September 1693

Item

Identifier: Coll-33/Folio C [181]

Scope and Contents
For Gregory's Nota to Newton's Principia. One of several attempts (see C46, C60, and C63) to understand Newton's corollary 2 to proposition 91, book 1, which discovered the ratio of the attraction of a shpere to that of a spheroid, and involved the integration of the square root of a trinomial.

**Dates:**15 September 1693

### Adnotata ... ex Newtone, May 1694

Item

Identifier: Coll-33/Folio C [43]

Scope and Contents
Notes of some of the consultations with Newton in Cambridge from the 4th to the 8th of May, 1694. The topics of those talks included astronomy, mechanics, physics and mathematics. The mathematical topics included conic radii, conjugates of curves, the polar coordinates of an orbit, and the form of the solid of least resistance.

**Dates:**May 1694

### Adnotata Phys: et Math: de Newtono 1698..., 1698

Item

Identifier: Coll-33/Folio C [62]

Scope and Contents
Thoughts on Newton's theory of the moon. Gregory notes Fatio's success in deriving the inverse square law, and Flamsteed's refusal to supply orbital data.

**Dates:**1698

### Chartae 4. fol: de Nostra 2da Quadrandi Methodo, 1686

Item

Identifier: Coll-33/Folio C [206]

Scope and Contents
A tranche of workpapers in which Gregory continues to labour on adapting Newton's method of quadrature. He continues to have trouble adapting the basic series, an indefinite integral, to the definite integral defined between O and x.

One paper among these was probably intended for the Astronomiae, showing a body moving in an ellipse.

**Dates:**1686

### Corrigenda to the Astronomiae, 1698-1699

Item

Identifier: Coll-33/Quarto A [56(3)]

Editorial issues in Gregory's major textbook.

**Dates:**1698-1699

### Extrait de Manouvre des Vaisseaux ... sequuntur ... de Newtoni cogitatio, 1694

Item

Identifier: Coll-33/Folio C [57]

Scope and Contents
A jotting, dated 1694, about a book on how vessels turn (for Gregory was interested in how solids behaved in fluids), and diagrams on the catenary curve, annotated annoted by Gregory and by Newton, almost certainly during their five-day meeting in Cambridge in May of the same year.

**Dates:**1694

### Folio C, c1680-c1708

Series — Volume Dc.1.61: Series Coll-33/Folio C

Identifier: Coll-33/Folio C

Scope and Contents
The papers of David Gregory consist of:
These are mostly handwritten items, bound together as a volume, though with some loose insertions of manuscripts which had strayed, some of them with modern annotations concerning their provenance. Their scope and content is as David Gregory indexed them, save for the missing items, which consist of two dozen papers and letters on general physics and maths, and several...

**Dates:**c1680-c1708

### In editione nova Philos: Newtoniana haec ab Auctore fient, May 1694

Item

Identifier: Coll-33/Folio C [42]

Scope and Contents
These are the things that Gregory was able to copy into his notes or his own copy of the Principia from those things which Newton had altered in his own copy. He proposed that these be published as a volume of Notae if not as a second edition.

**Dates:**May 1694
