Mathematical manuscript largely comprised of a fair copy, without attribution, of the problems, diagrams, and Euclidean references of John Speidell's Geometricall extraction, first published in 1616. Followed by 8 illustrated propositions on measurement, with reference to Edmund Gunter (professor of astronomy at Gresham College, f. 55v) and possibly based on his Description and use of the sector, the crosse-staffe and other such instruments, first published in 1623. The illustrated title page is heavily based on the title page of Gunter's collected works. At the end of the mathematical material, 4 historical documents are bound in: 3 copies of official documents in English on paper from between 1616 and 1621, and a fragment (3 leaves) of a 15th-century land register in Latin on parchment that includes names of communities in southern England such as Larkehyll (Larkhill) and Suthinhame (Southampton). Folio format; the documents are on guards and are folded to fit within the binding, and the paper documents (f. 61-75) are on a mix of folio singletons and bifolia.
