Casing: leather with gold tooling. 4-stave MS paper. Watermark: Coat of arms containing a fleur-de-lis, and the initials "P T". In a single hand (the same as 442/39c).
Contents (and concordances with the other volumes) are given below: titles of pieces are taken from 442/39b unless otherwise stated. Original pagination [sic] in ink. Foliation added for cataloguing. Each air also has 1-2 numbers at its head (not included in the catalogue entries); the numbers do not always agree amongst the three volumes. In the part of each entry where the metre is given, quotation marks around a "2" or a "3" indicates the original has a slash through the number. Many additional proportional metric signs are used in this source.
