The manuscript was written between 1664 and 1669 by 'Conradus Gleskinski, Germanus'. After a dedication to Sir Philip Warwick ('Magnificentissimo nobilissimo domino domino Philippo Warwick equiti aurato'), beginning 'Non necessum habeo ut linguam Slavonicam', the manuscript contains (1) 'Alphabetum Slavonicum'; (2) St Paul's epistle to Philemon, the Lords' prayer, and the numbers from one upwards, written out in three lines, in Slavonic, Slavonic in Roman characters, and English. The last four leaves of the manuscript are occupied with a list of persons who conferred benefits on the writer; they are mostly Cambridge and Oxford clergymen, e.g. 'Dominus Barrow Coll. Trin. Math. Prof. in aula publica me lauto prandio excepit et dedit 10 sol', 'Rev. dominus Pierce vino Hispanico me tractavit et dedit 17 sol', etc.
