RECALL OF PICTET'S EXPERIMENT (COOLING BY CASCADE PROCESSES AND JOULE-THOMSON EFFECT) AND OF CAILLETET'S EXPERIMENT (LIQUEFACTION PROCESS BY ADIABATIC EXPANSION WITH EXTERNAL WORK). APPLICATION OF THE ISENTROPIC PROCESS FIRST USED BY CAILLETET TO PRODUCTION OF MILLI-AND MICRODEGREE KELVIN TEMPERATURES. THEN, USING THESE EXTREME LOW TEMPERATURES FOR PRECOOLING, LOWER TEMPERATURES, OF THE ORDER OF NANODEGREE KELVIN, CAN BE OBTAINED BY ADIABATIC DEMAGNETISATION OF THE NUCLEAR SPIN SYSTEMS. J. V.
