This collection contains a contemporary red morocco-bound calligraphic manuscript prayer book in three parts. The cover has elaborate gilt borders, and the spine has gilt compartments and lettering, with marbled endpapers. The first and largest section, Explications des Cérémonies de l'Église avec les Prières, contains prayers keyed to specific moments of the Mass, accompanied by twelve colored vignette illustrations. The two shorter appended sections are "Les Sept Psaulmes de la Pentience" (Seven Penitential Psalms), and "Les Litanies des S.ts" (Litanies of the Saints), both of which have titles written in gold ink on a blue wash background, similarly within the blue and red borders of the first part, but with initial letters gilt on a blue wash. The half-title includes a note by one of the manuscript's owners, A. [Arthur] Dinaux (1795–1864), on the book's provenance. The note explains the contents of the book and notes a former owner had written on a flyleaf that it "qu'il provenait de l'oncle germain de M .Aubrey le 14 février 1765(?). C'est la seule date qu'on découvre dans ce manuscrit." The flyleaf is no longer present with this manuscript.
