Ad Jo: De Witt Elem: Curvarum, 1680
A demonstratio on one of de Witt's notes on Schooten's 1659 Latin edition of Descartes' Geometria. Unrelated jottings on reverse are in a hand other than Gregory's.
Curva foliata, c1693
Diagram and mathematical description of a foliate curve. A modern hand has pencilled in "7 a Schooten", referring to geometer Frans van Schooten (1615-1660).
De ratione studii mathematici consilium, 1693
Draft, not in Gregory's usual hand, of a paper written for the direction of students. Another copy, under this same title, is in Francis Pringle's notebook, Dc.6.12. Two others, under different titles, are in Folio C (see below), as number 112, and in fol. 85 of the Royal Society of London's MS 247.
Excerpta de Codico M.S. Henratii communicata a [illegible], 27 May 1693
Extract of a volume (only partially cited) found by David Gregory in Amsterdam. He captions this "F: a. Schoten', suggesting that the work transcribed is that of geometer Frans van Schooten (1615-1660). The work concerns curves and quadratures, and is laced with comparisons to the work of Jan Hudde.
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.
Notata in D: de Witt Loca plana et solida, 1696
12 pages of commentary on De Witt's notes in Schooten's 1659 edition of Descarted. The last page appears to have been bound out of sequence; part of this document was inadvertently misnumbered by Gregory as item 3.
