Visitors book to the Sir Isaac Newton Exhibition, 13-31 August 1951.

Written in England. Contains the curious characters known as the Boetian contractions, and is a valuable document for the history of arithmetic. The treatise commences on the Roman abacal system, and afterwards proceeds to give an explanation of the Eastern Boetian system with altered characters, and with a complete adoption of the advantages of local position. In Folio 2, recto, line 5, the author says that he will expound 'quaedam de numerorum scientia. regulis uidelicet algorismi' and on Folio 3, verso, he refers to Pithagoras, Nicomachus, Apuleius and Boethius. The text ends on the first line of Folio 34, recto, and is followed by eight lines in a semi-current 13th century hand.

Transcript extract from line 14 ' Prima itaque omnium est igin. 1. id est unitas. Secunda andras. 2. id est binarius. Tercia ormis. 3. id est ternarius. Quarta arbas. 4. id est quaternarius.

Singule ataque figure in quocumque loco sint sui ipsius exprimunt significationem. Nunquam enim figura unitatis officium binarii sibi usurpabit, nec binarius ternarii, nec ternarius quaternarii, nec quelibet ceterarum quod alter significare poterit. Ad majorem itaque evidentiam significationes locorum ponamus. primo ita loco posita igin seipsam, id es unitatem, significat. Secundo denarium. Tercio centenarium. Quarto millenarium.

Originally two rows, each of twenty four folds, but the first folds in the lower row ( lower if the sheet is looked at from the side containing art. 1) are missing and the first fold in the upper row has been sewn to the foot of the second fold. Three membranes were joined to make a sheet.

Entries in red include Edwardii Regis and Translacio Edwardi Regis (20 March, 13 October); in black, Translacio Mildride (13 July). Each feast is illustrated by a conventional head, sideways, in coloured penwork: kings crowned, abbots tonsured etc. The ruling is in red and green inks.

On the other side, the other way up: (a) in the upper row, the sign of the zodiac in each month, followed by its occupation; (b) in the lower row, an astronomical calendar, 1 january to 15 June on 22 folds, four to a month.
