(b) Permit (in French) for Pigott to use a French institute’s library (addressed to Pigott at Hotel de Nantes, Paris). Undated. The reference to ‘institut’ may refer to L'Institut national des sciences et des arts, which would date it after 1795, presumably to Pigott’s stay in France after the Peace of Amiens.

(d) Draft of a letter of June 1792 from Pigott to M. Cassini of the French Academie Royale de Sciences (in French), thanking him for sending the continuation of ‘L’extrait des observations astronomiques’, noting that he had just returned after a six-year absence to their observatory and intended to recommence his ‘amusements Astronomiques’, and offering to make astronomical observations from York. An explanatory footnote (in English) refers to M. Mechain, ‘whose correspondence I first did neglect; but who soon after, printed in the Connais: d. Tems [Connaissance des Temps], the proper motion of Beta [Virginis] without mentioning me – as also my improved method of determining diff. of Merid:ns by the Meridian [Moon] & not a word of me – also the Long: & Lat. of York without my name to it -’.

Summary of contents and extracts have been provided by a volunteer.
