English: A standard deposit gauge for collecting and measuring particulates such as soot in air pollution (see the Wikipedia article "Deposit gauge" for a technical and historic description). This photo comes from p.79 of the book "The smoke problem of great cities" by Napier Shaw and John Switzer Owens (London, Constable & Company, 1925) and (from the text) was probably used in the first scientific experiments featuring deposit gauges, published as "The Sootfall of London" in the Lancet, 1912. |
