Some more stereo views of the dioramas at the Natural History Museum in Los Angeles. The Walrus group is a popular subject for dioramas. There is a beautiful one at the American Museum of Natural History with a background painting by Francis Lee Jaques. When a taxidermist took me round the dioramas at the Zoological Museum in Copenhagen the thing he was most proud of was the representation of excrement on the show and ice. The natural history museum in Stockholm has a similar fascination with faeces. Such polution clearly made much less of an impression on the American surveys, for in both examples the snow is a pure white.
