TitleLetter, from [James] Gregorie to John Collins, dated at St Andrews
Date5 September 1670
DescriptionAddressed "to his worthy friend Mr John Collins at the Three Crownes in Bloomsbury Market".

Has received books from Collins a few weeks ago and thanks Collins. Will send fuller answer and some "lucubrations" of his along with Lord St Andrews [James Sharp, Archbishop of St Andrews] who will travel to London in the middle of October.
Discusses hyperbola and the construction of logarithms.
Has read Barrow's lectures with pleasure and attention, comments on the originality of his general geometrical method and what differentiates it from his own. Admires Barrow's 11th and 12th lectures but wishes he had included the solution to a problem Gregorie has been finding difficul and despairs to resolve. Longs to see [Isaac] Newton's method. Considers that Barrow has made such considerable advances in his 13th lecture that nothing can be added to it. Hopes [Christian] Huygen's work will appear in print soon and to be given any news related to the debate [on movement of planets] between [Jean Dominique] Cassini and [Nicholas] Mercator as he hopes to add to it himself.

Figure at the bottom of page 2 in Collin's hand with the annotation: "the first of the 12th lecture by which the surfaces of the pronoids are given."
Paragraph relating to Barrow's method underlined in red and quotation marks in pencil in the margins.
Annotated 'No. 16: p. 95' in reference to the inclusion of underlined paragraph related to Barrow in the 'Commercium Epistolicum' 1722 edition, page 95, paragraph XVI, in Latin translation.

Annotated at the top of the address page: "A Problem proposed to Dr Barrow 5 September 1670" in Collins' hand.
