De affirmanda parallaxi magni orbis, cogitatum Hugenii, June 1693

Identifier: Coll-33/Quarto A [15]
Scope and Contents A transcription of Christiaan Huygen's argument that because stars' observed radii are so insensibly small, the diameter of the earth's orbit relative to the stars' position is also insensible, and thus the parallax measurement, which ought to prove or disprove the Copernican layout of the heavens, is useless.
Dates: June 1693

De Antlia Pneumatica ..., 1681

Identifier: Coll-33/Folio C [9]
Scope and Contents Notes from a trip to London in May and early June of 1681. Gregory saw Boyle's pneumatic pump (an 'antlia' is a siphon) and a method of making 'leaves' with molten glass and water. One Mr Lamb discussed copper engraving with him. He saw Newton's reflecting telescope in Gresham College.
Dates: 1681

De gyratione Globorum de collisione mutua Probl: Halleianum 3, c January 1695

Identifier: Coll-33/Quarto A [7]
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.
Dates: c January 1695

De resolutione equationum cubicarum, 1684-1696

Identifier: Coll-33/Folio C [20]
Scope and Contents Notes on a universal theorem on the forces on inclined planes, possibly part of his notes on Huygen's Horologium Oscillatorium, now lost.
Dates: 1684-1696

Descriptio Machinae ad Planetarum Motuu exhibendum ... in obsero: Paris, 1680

Identifier: Coll-33/Folio C [165]
Scope and Contents Diagrams and explanations of things Gregory saw in Paris in December of 1680: a pendulum of the sort used in Huygens' famous horologium, an enormous quadrant, and the moving planetary model of one Dr Romer. This was probably the Danish astromechanic Ole Roemer (1644-1710).
Dates: 1680

Dr Gregorys solution of the same, s.d.

Identifier: Coll-33/Folio C [95]
Scope and Contents Gregory's solution to the specific gravity problem in item C 94.
Dates: s.d.

Dr Oliphants Solution of Mr Boyles Probl: about the specifick Gravity of bodys, s.d.

Identifier: Coll-33/Folio C [94]
Scope and Contents A basic problem in physics. The hand may not be Gregory's. ' Dr Oliphant' may be Charles Oliphant, disputant in a furore over an anonymous tract lampooning Archibald Pitcairne in 1695, or perhaps David Oliphant, librarian to Glasgow University 1691-1671. Item 94 in Quarto A happens to be titled, 'Memoranda pro Arch Pitcarnio et C. Oliphant'. See also unlabelled page between C 100 and C 102 (which is not C 101--that being out of sequence, glued to the back of C 97).
Dates: s.d.
