Camera An Aid To Diagnosis

A Manchester, Eng., photographer relates that he once took a photograph of a child who was apparently in good health and had a clear skin. The negative showed face to be thickly covered with an eruption. Three days afterward the child was covered with spots due to prickly heat. The camera had seen and photographed the eruption three days before it was visible to the naked eye. It is said that another case of a similar kind is recorded, where a child ehowed spots on his portrait which were invisible on his face a fortnight previous to an attack of smallpox.
