The Rules of the Holy Apostles and the Holy Seven Councils of the Church on such subjects as deadly sins, good and bad days, the holy Sacrament, priests and monks, in Slavonic, a work in thirty-nine chapters; preceded by a table of the chapters. Among them are the Questions of st. Cyril, the Questions of st. Niphon, bishop of Novgorod, and others, and the rule of st. Theodore for his monastery.

Fols. 2-18 are occupied by a little primer of Russian spelling, consisting of letters, syllables, and easy words, closing with the Lord's Prayer and a monogram, all written about A.D. 1600 (?). This was in 1610 in the possession of Thomas Thomson, an Oxford M.A. (of Brasenose college?), a native of Hudswell in Yorkshire, who on Aug. 24, 1622, wrote an astrological note about certain coloured banners significant of the weather, in English. This piece clearly does not properly belong to the volume, though now fastened in it.
