Northern gothica textualis (s. XIII): striking difference between bold and hairlines. Small "s", "h", and feet of minims nearly entirely closed with hairlines. The ascender of the "d" can b slanted, straight with flat top, or looped. Frequent abbreviations, not in musical notations. Later additions in margins, possibly calculations and library references from 18-19th century.
