It is housed within its own unique black Solander box with a gilt title in rule to spine. The Solander box is named after the Swedish botanist Daniel Solander (1733-82), who is credited with constructing a box capable of storing valuable material while working as 'Keeper of Printed Books' at the British Museum. A Solander is used mostly in libraries and places storing archive material, including maps, prints, and manuscripts. 103 leaves (wanting at least seven others, probably bearing miniatures, from the Hours of the Virgin and elsewhere), two surviving miniatures with illuminated borders, four further pages with illuminated borders, 4-, 2- and 1-line initials in burnished gold or colours, text mainly in Latin with some prayers in Flemish, leaves at the front (calendar) and rear corroded with some loss, some damp staining, and browning, one or two old repairs, ink stamp of the Abbé Haffreingue and inscription 'Alberto Ruskin Cook fratri amato D.D. frater amantissimus Arthurus Bernard Cook A.S.
