Autograph letter signed from Colin Maclaurin announcing his intention to write A Treatise of Fluxions, 16 November 1734

Autograph letter signed by Colin Maclaurin addressed to James Stirling "at Mr Watt's Academy in the little Tower Street, London", dated 16 November 1734, announcing his intention to write A Treatise of Fluxions ("Upon more consideration I did not think it best to write an answer to Dean Berkeley but to write a treatise of fluxions which might answer the purpose and be useful to my scholars. I intend that it shall be laid before you as soon I shall send two or three sheets more of it to Mr Warrender that I may have your judgment of it with all openness and liberty … Robert Simpson [sic] is lazy you know and perhaps has not considered that subject so much as others. But I can entirely depend on your judgment. I am not at present inclined to put my name to it … I have some thoughts in order to makesome of Mr De Moivre’s theorems more easy which I hope he will not take amiss"), and discussing other matters (his search for a copy of Machin’s book on the moon; "I observe in our news papers that Dr Halley has found the longitud"', etc.).
