Spectroscopic observations of the Nal D emission lines of prominences were made with the Domeless Solar Telescope in Hida Observatory. When active prominences are bright in the D 2 emission line, the intensity ratio of D~ to D 2 is found to deviate significantly from the theoretical ratio of the opt
