Etching by T Sopwith of the geologist William Buckland (1784-1856). Buckland was Profesor of Geology and Mineralogy at Oxford. This humourous depiction, subtitled 'Costume of the Glaciers', shows Buckland wrapped up in layers of warm clothing and carrying a variety of equipment including 'Maps of Ancient Glaciers' and tools for taking rock samples. Those at bottom left show scratches from a glacier made thousands of years ago, and scratches made by a cart on Waterloo Bridge 'the day before yesterday'. Sopwith has even signed the portrait as 'scratched by T Sopwith'.
