Ex Scriptis H. van Heurat, s.d.
A writeup of Heurat's theorems on the quadrature of curves, possibly written out by one 'D Verwer'.
Ex Tschurnhausii Theoremate et Methodo Deducitur Canon meus, 1688
A 11-page tranche of workpapers in which Gregory derives his own conclusions from the work of Tchirnhausen.
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.
Explanation of Symbols, c1780-c1803
Volume contains manuscript notes on the symbology of mathematics and engineering, followed by miscellanea on dymanics ('wheel carriages' being a special topic). There are some minor diagrams, and some of the terms are glossed with Russian.
Extracta ex Journales des Scavans, after 1682
Notes on curves, taken "ex transact: philos: gallicis 1682".
Extrait de Manouvre des Vaisseaux ... sequuntur ... de Newtoni cogitatio, 1694
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.
Fluxions, c1780-c1808
Volume contains manuscript notes on the calculus.
