A number of large three-dimensional models of important areas were on display in the Museum. Specific guides were published to describe the models. The first was a general guide to all the models in the Museum of Practical Geology in Jermyn Street and dated 1865, others were somewhat later between 1906 and 1932 and covered Assynt Mountains, Ardnamurchan, Ingleborough and district, the Thames Valley and the Isle of Purbeck. For convenience the Description of Arthur's Seat Volcano is included in this series, though the model was displayed in the Royal Scottish Museum.
