The collection comprises two manuscript volumes. The first (MS 13/1) contains 19th century transcripts of 24 letters between John Wallis and the Rev. Edmund Elys, dated December 1690 to April 1699. The letters contain discussion on religious and theological issues.
The volume also includes transcripts of three letters from John Wallis to Dr Thomas Smith, 14 July 1692, 6 July 1697 and 21 December 1698; and a transcript of a letter from Dr Arthur Charlett to the Archbishop of Canterbury [Archbishop Thomas Tenison], 22 September 1700.
All of the transcripts are in the same hand but the identity of the transcriber is unknown. On the first page of the volume, a note states that the correspondence was copied from a volume then in the possession of Joseph Parkis Esq. The current location of the original letters between Wallis and Elys is unknown. No other letters between them are listed in C.J. Scriba, 'A Tentative Index of the Correspondence of John Wallis, F.R.S.', Notes and Records of the Royal Society, 22 (1967), 58-93. The originals of the remaining four letters are now in the Bodleian Library, Oxford.
The second volume (MS 13/2) contains a transcript of treatise in which Dr Wallis criticizes Lewis Maidwell's proposals for an Academy. The original manuscript was written in November 1700, with a supplement dated January 1700/01. The treatise is followed by extracts from the Journal of the House of Commons relating to Maidwell's proposals, dated 1699-1705. At the end is a transcript of a paper posted by Professor [Nathaniel] Bliss, Savilian Professor of Geometry from 1742-65, inviting scholars to attend his house to discuss mathematical issues.
All of the transcripts are in the same hand, which is different from that in MS 13/1, but the identity of the transcriber is unknown. The introduction to the volume states that the treatise was then unpublished, and had been 'copied from the Original in Dr Wallis' own handwriting, which is preserved in the Savilian Library, at Oxford [now part of the Bodleian Library's collections of rare books and printed ephemera], MSS No. 57. It has since been published and edited by the Oxford Historical Society.
The date of the transcripts in both volumes is unknown but the style of handwriting and stationery used suggests a date around the middle of the 19th century.
