Chetham's Library, Manchester, MSS/1/227, Finding no. A.3.110. The catalogue entry reads: “Notebook [by William Gascoigne (1612?–1644)] containing notes in English taken from the 1632 edition of Lansberg's Tabulae Motuum Coelestium.” The manuscript was obtained from the 1883 sale of the Towneley Hall library and was listed in the sale catalogue as “A new and true theory of the sun's motion. MS”. The notebook is 118 pages long and largely consists of a verbatim English translation of Lansberg's Novae & genuinae motuum coelestium theoricae, which was appended to the 1632 edition of Tabulae motuum. The verso of the first page of the notebook has several attempts at a latinized version of Gascoigne's signature, but these are dissimilar to the uniform signatures on the three known Gascoigne letters. The handwriting throughout the notebook, although similar to that of the letters, does have some important differences (e.g. the rendition of the word “of”) and careful study is required in order to determine whether it is indeed written by William Gascoigne.

CavendishCharlesJohnPell, 16, British Library MS Add. 4278, ff. 180–1 (transcribed in John Pell (1611–1685) and his correspondence with Sir Charles Cavendish by MalcolmNoelJacquelineStedall (Oxford, 2005), Letter 14, 369–70). Note: The same letter transcribed in Correspondance du Père Marin Mersenne, ed. by de CornelisWaard (Paris, 1932–88), xiii, 204–5, is incomplete and omits the piece about Gascoigne. One wonders whether the antecedent letter from Pell to Cavendish in Malcolm and Stedall's work is also incomplete, since Pell does not ask any question about Gascoigne, even though Cavendish appears to be answering one. Although the letter was written a month after the Battle of Marston Moor, in which Gascoigne was probably killed, Cavendish does not seem to be aware of Gascoigne's demise.

My first businesse in London, was to seeke for Galileo's Dialogues; I thought it a very good bargain, when at taking my leave of your Lordship I undertooke to buy it for you, but if your Lordship should bind me to performance it would be bad enough, for it is not possible to get it for money. There were but few brought over at first, and they that buy such bookes, are not such men as to part with them againe. I heare say it is called in, in Italy, as a booke that will do more hurt to their religion then all the bookes have done of Luther and Calvin, such opposition they thinke is between their religion, and naturall reason.
