title: Specimen holder improvements for the study of amphibian skin pigmentation.
abstract: A skin specimen holder was constructed permitting nearly identical experimental conditions during in vitro spectrophotometry and photomicrography of amphibian skin melanocytes. The specimen holder was made of non-corrosive steel thread and made to fit a spectrophotometer cuvette and the light microscope stage. The improvements were compared to earlier constructions.
