Amongst other material, a naturalist took a photograph of a dead dog on a beach. The corpse was a week old and covered in flies. The naturalist returned home, took a film from his camera and sent it to a reputable laboratory. The film was developed and printed and returned by post to the naturalist who opened the small parcel in his study. Comparing the prints with the negatives the naturalist had cause to hold one of the photographs in his teeth. It was the negative of the dead dog on the beach. That evening the naturalist died of an infection.

His body, covered in flies, was found by the police a week later and photographed.
