Chartae 4. fol: de Nostra 2da Quadrandi Methodo, 1686
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.
Commentarius in D.G. Quadrature: in D.P. Probl: de inventoribus, June 1692
Gregory's further commentary on the problem laid out for him (and John Young) in 1688.
Curva Cragio exhibitur, July 1687
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.
Folio C, c1680-c1708
Index Chartarum in M.S. C. in folio, 1700
An index, in Gregory's hand, to the material he designated as Folio C.
Memoranda pro Arch Pitcarnio et C. Oliphant, 1695
A list of collegial favours to ask of Dr Gregory, presumably on his return home from Holland.
Primo designatur..., 1680's
Problemata Proposita J. Young a D. Pitcairne, 1683-1687
Broadsheet excerpts of the problem and condemnation in the joust between Archibald Pitcairne and John Young, which lost the latter his mathematics chair at Edinburgh. There follows a rumination, perhaps in Pitcairne's hand or perhaps Gregory's, on scientific education.
Propositiones D.A. Pitcairnei, c1692
4 scraps, the first three in Archibald Pitcairne's hand, containing scrawled thoughts on one or two geometric processions, and numerous fragments of book titles, names, and addresses, apparently all relating to Gregory's time in Holland. These may be all that is left of item 92.
