A total of 50 spiral galaxies that were detected at low galactic latitudes at 21cm using the Arecibo Observatory 305m telescope were used to compare their POSS II images with their 2MASS images.These galaxies were studied in order to find a criterion to classify morphologically infrared images of galaxies and compare them with their optical counterparts . To remain permanent members of a continuous congress would be to establish a power that is certain sooner or later to be abused .
