Edinburgh has long been recognized as one important place where early glacial theory was promoted and debated. This paper, rather than attend to the longer-term development of glacial theory, focuses on the ways in which the theory was assessed, disseminated and received in and through the scientific culture of early Victorian Edinburgh. Edinburgh's scientific and educational societies, science journals, newspapers and field sites are brought to view through examining their engagement with, and use of, early glacial theory. Tracking the theory's passage across a range of spaces bound up with the promotion of geology in mid-nineteenth-century Edinburgh signals relations between local geological endeavour and other sorts of scientific and cultural work. Particular, though not exclusive, attention is given to practices more readily defined as ‘popular’.
