Notata Math. Nov: 1702, November 1702

 Item
Identifier: Coll-33/Quarto A [62(2)]
Scope and Contents

This small page appears to go with item 61(2), Newton's refraction table. 1702 was the year that the Astronomiae came out, by which time Gregory was also well under way with his ancient geometers project.

Dates: November 1702

Notata phys: et math: London ..., 1697

 Item
Identifier: Coll-33/Quarto A [78]
Scope and Contents

Notes on scientific matters, many of them discussed with Newton, such as why the brachistochrone curve is a cycloid and how a musical chord can have the figure of a catenaria, and a record of curiosities, such as the toads of Surinam, who breed their young on their backs, and floors that can be secured made with dovetails instead of nails.

Notata phys: et math: London ..., 1698-1705

 Item
Identifier: Coll-33/Quarto A [80]
Scope and Contents

Almost certainly a latter part of Gregory's item 80: 'Notata Phys: et Math: D.G. Lond: 25 June &c 1698'. This covers cone sections, elements of Euclid, errata in a Halley treatment of comets in his own Apollonius project, and a jotting on Scottish history bibliography.

Notes on priority, 1707

 Item
Identifier: Coll-33/Folio E [038]
Scope and Contents

This small slip bears what appears to be ammunition in Gregory's defence of his uncle James Gregorie against old charges of plagiarism. The confusing reference to "Actis Phil. Septemb. & Decemb. 1797" is a slip of the pen. The material appeared in the Acta of 1707.

Observ: Eclipsos Lunaris Oxon 19 Octr 1697 et [Mercury] in [the Sun] 24 Oct 1697, October 1697, with 2 apparently attached documents from 17041693

Identifier: Coll-33/Quarto A [28]
Scope and Contents Two straightforward records of planetary eclipses, but meant, on palaeographic evidence, to be kept with a draft and a fair copy of a subsequent Philosophical Transactions of the Royal Society article [Vol. XXIV, No. 293, for September-October 1704, p1704] about the Cassini curve, a model of how a periodic comet probably orbits. Folding and fading of these documents suggest that they were inserted not long after David Gregory generated his index of Quarto A (which he drew up around 1700)....

Observata et dicta apud D. Hugenium, 06 June 1693

 Item
Identifier: Coll-33/Quarto A [4]
Scope and Contents

Notes of a conversation in Holland with Christian Huygens, concerning an 'horologium' to show hours, months, years, and planetary positions. More general mention of the work of numerous other scientists: Notably, Huygens disputes the notion of John Bernoulli (James Bernoulli's younger brother) that the curve of an inflated sail is part-catenary and part-circle, and warns that Newton ought not to be 'deflected' into theology or chemistry.

Scope and Contents A treatise on general arithmetic by the celebrated astronomer Ghiyās al-Dīn Jamshīd b. Mas'ūd b. Maḥmūd al-Ṭayyib al-Kāshī, commonly known as Al-Ghayyās, (d. ca. 1436 C.E.) who dedicated the work to Mīrzā Ulugh Beg, grandson of Tīmūr (see fol. 4b).

Scope and Contents This is a much more complete work of Euclid than the Greek text that has come down to us. It was translated from the Greek by the famous philosopher and astronomer Khwājah Naṣīr al-Dīn al-Ṭūsī (d. 672 A.H., 1274 C.E.) b. Imām Fakhr al-Dīn, and was brought to Spain by the Arabs, thence a knowledge of its contents was diffused throughout Europe long before the Greek original was discovered. In this work Naṣīr al-Dīn proves most of the propositions, sometimes in two, three, and four ways,...

Scope and Contents The treatise on conic sections by Apollonius of Perga, who was born in the reign of Ptolemy Euergetes, and died during that of Ptolemy Philopater, who ruled 222-205 B.C. It is stated on fol. 52b that Apollonius dedicated the first three books of his conic sections to Eudemus. The treatise was originally in eight books, of which only the first four were known in Europe. About the middle of the seventeenth century the next three books were translated from an Arabic MS. dated 1250 C.E. The...
