Fig. 1 i is a thermometer placed in the center of the oven for noting the temperature. Twenty grams of soil were placed in the receptacle, normal potassium nitrate solution allowed to percolate through, and titrated at room temperature with results as shown in Table IV. The temperature eflfect is very slight, and certainly does not indicate colloidal adsorption, unless this may be an exceptional case. (5).
