Ad Cartesis Specia ... sectionibus Coni, 1680

 Item
Identifier: Coll-33/Folio C [134]
Scope and Contents

Notes on Cartesian cone sections, written out during Gregory's stay in Rotterdam.

The item going before, also labelled 134, may actually be 133 (or part of it), which was supposed to have been a treatment by James Gregory on hyperbolae, nautical spirals, and other things. It treats of a hyperbola, at least. Its hand is not David's, but neither is it the hand of item C 136, in James' familiar hand.

Dates: 1680

Ad Philosophiam Neutoni Nota, 15 September 1693

 Item
Identifier: Coll-33/Folio C [181]
