This is one of four calotypes of young girls with David Octavius Hill?s dog, a terrier pup called Brownie. The girls depicted are the Farnie sisters; the eldest one, Annie, protectively holding the younger, Harriet, who is pretending to be asleep. Sleeping children were a recurring theme in nineteenth-century art, as it played on the Victorian fascination with childhood innocence and death. The image is clear and well-defined, which means that the girls must have sat very still for anything from several seconds up to a minute. Although the calotype was taken in the 1840s, this particular print was produced in the photography studio of Jessie Bertram around 1920. In total, 49 `new? prints were made from the original negatives and were subsequently published as an album.
