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

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

Curva Cragio exhibitur, July 1687

Identifier: Coll-33/Folio C [205]
Scope and Contents Gregory, probably with Pitcairne at his side, sent these curves to Craige in Cambridge, challenging him to find their quadrature. Thus the writing that is not in Gregory's hand may be Craige's.
Dates: July 1687
