A METHOD OF DETERMINING A CHARACTERISTIC OF A POROUS MEDIUM WHICH COMPRISES OBTAINING A SAMPLE OF SAID MEDIUM, SATURATING SAID SAMPLE WITH AN ELECTRICALLY-CONDUCTING LIQUID, PREPARING A DISPERSION WHOSE CONTINUOUS PHASE IS OF THE SAME COMPOSITION AS SAID LIQUID AND HAVING A DISPERSED PHASE OF HIGHER ELECTRICAL RESISTTHAN SAID LIQUID, MEASURING THE ELECTRICAL RESISTANCE OF AN ELECTRICAL CELL FILLED WITH SAID LIQUID, MEASURING THE ELECTRICAL RESISTANCE OF SAID ELECTROLYTIC CELL FILLED WITH SAID SATURATED SAMPLE SURROUNDED BY SAID LIQUID, MEASURING THE ELECTRICAL RESISTANCE OF SAID ELECTROLYTIC CELL FILLED WITH SAID DISPERSION, AND MEASURING THE ELECTRICAL RESISTANCE OF SAID ELECTROLYTIC CELL FILLED WITH SAID SATURATED SAMPLE SURROUNDED BY SAID DISPERSION WHEREBY A CHARACTERISTIC OF SAID SAMPLE MAY BE COMPUTED FROM SAID MEASURED RESISTANCES.
