Seriatim cold-mapping was carried out upon totally untrained subjects with 2 mm and 3 mm stimulators at 17[degree] C. Each square of a checkerboard pattern was stimulated 6 times during a period; repeated mappings being made the same day and also for several days in succession. Three indications of consistency are found: (1) reliability coefficients of .85 or better are obtained in the majority of cases when successive periods are compared; (2) charts of average against individual scores show low mean deviations and few "wild shots"; (3) maps derived from average scores indicate a high degree of orderliness, even when the reliability coefficients are low. Seriatim cold-mapping is a promising research technique. Certain avenues for further investigation are suggested.
