A few years aro Comber of the Rothamsted Station (England) suggested the use of a four per cent solution of potassium thiocyanate in 95 per cent alcohol as a means of testing soils for acidity. This method has been modified by substituting acetone and ether for the alcohol and has been more or less widely adopted for testing f ield soils, provided the soil is in a dry or almost dry state. The results on moist soils are more or less doubt fu l , consequently the use of such a solution by the field man is decidedly limited.
