Scope and Contents

Treatment of Sir Edmond Halley's method of finding the rotary motions produced in two spheres by an oblique impact. Appears to have been written in a hand other than David Gregory's, [Halley's?] though the title is clearly in his.

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...

Scope and Contents The constitution of the Folio E papers of David Gregory follows: The documents' order is random, but the collection has several foci. One is David Gregory the academic's need for books. Numerous shopping lists for titles abroad reflect this, (one of which also includes a requirement for tea), as do inventories of other people's libraries nearer to home. Another focus in the collection is Gregory's public...

Scope and Contents

5 unconnected pages from Halley's published translation of Apollonius, dedicated to Henry Aldrich, whose grant had funded the project.

Scope and Contents

An index, in Gregory's hand, to the material he designated as Folio C.

Scope and Contents

A critique of the Keplerian ellipse from William Whiston's Praelectiones, (1707), which were also published in English in 1715 and 1728. Gregory's handwritten note at the bottom suggests that he or Sir Edmund Halley helped with corrections.

Scope and Contents The papers of David Gregory in Quarto A consist of: 107 manuscript papers and an index, relating to: theoretical physics, including optics, especially treatises on refraction and colour, on mechanics, specifically on velocity, gravitation, centrifugal and centripetal force, and the movement of solids through fluid, and an occasional thought on magnetic attraction. Applied physics, considering ships,...

Scope and Contents

David Gregory's solution to Sir Edmund Halley's problem, proposed during Gregory's composition of the "Tract on Fluxions", of finding the rotary motion in a sphere struck by another sphere. (Halley's solution is in Coll-33/Quarto A [7].) It is built on some basic lemmas and includes a reference (possibly after the date given) to proposition 40 of the "Tract on Fluxions".

Scope and Contents

List of corrigenda for an unspecified work, almost certainly Catoptricae et Dioptricae Elementa, (1695), or the Edinburgh optics lectures from which this work proceeded.

Scope and Contents Note of some Arabic versions of Apollonius' "Sectio Ratione" in the Bodleian Library, that possess Latin glosses by Edward Bernard, Gregory's predecessor in the Savilian Chair of Astronomy, and one other person. Bernard had wished to publish the works of the ancient mathematicians; this manuscript he found defective and abandoned, unable to translate completely. [His partial translation was copied out by Gregory as B37, and used by Sir Edmund Halley to learn enough Arabic to translate the...
