Below are presented rocks and minerals selected by famous mineral dealer James R. Gregory of Victorian London, England, and arranged in two wooden boxes, one formed of two trays for the rock collection (Fig. 1) and one formed of four trays for the mineral collection (Figs. 2-3). Each tray contains 50 specimens, meaning a total of c. 100 rock specimens and c. 200 minerals in the collection. Originally, each specimen carried a small sticker with its collection number typed on it and was accompanied by a James R. Gregory label. Some specimens are unfortunately missing. Others lost their number and may be mislabelled. The address on one box label (Fig. 4, 88 Charlotte Street, Fitzroy Square, London) indicates the collection would have been prepared in the period 1874-1895. Some specimen labels give however another address (15 Russell Street, Covent Garden, London), which indicates that these specimens would have been labelled in the period 1866-1874. Similar portable collections were common in the 19th century as educational tools for geologists. They are nowadays relatively rare and praised by collectors. We purchased this collection in 2011 from an estate in Staffordshire, England. It now forms the Special Collection B of the Tricottet Collection.

Rock collection catalogue

Table 1 lists the sedimentary rock specimens, no. 1 to 72 from the rock collection (Fig. 1), and Table 2 the igneous and metamorphic rocks, no. 73 to 100. The two tables follow the exact description given by the Gregory labels (Figs. 5-6). When a word could not be identified, it has been replaced by "----". Sedimentary rocks are arranged chronologically from the most recent to the oldest one. All specimens come from different regions of United Kingdom making this collection a rare memento of 19th-century regional geology. Most specimens come from type localities, some being nowadays Sites of Special Scientific Interest (SSSI).
