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

 Item

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)....

 Item

Identifier: Coll-33/Quarto A [14]

Scope and Contents

Remarks en passant about library volumes in history and physics seen in Leiden. A longer passage follows: notes to a conversation with Christiaan Huygens, critiquing Sir Isaac Newton's notions of absolute motion and the propagation of light. Huygens also says that John Flamsteed ought to declare for the absolute speed of light, and that this should persuade Jean Dominique Cassini.
