The foregoing results are really of the highest importance. They show 

 that by employing the same amount of soil and the same quantity of 

 water entirely different depressions are obtained in the diverse classes 

 of soil. The magnitude of the depression ranges form .017 in the case 

 of sand (Soil No .13) to 1.245 in the case of clay loam (Soil No. 19), or 

 a difference of over 73 times. The variation between the other soils is 

 not as great as this, but certainly sufficiently great. 



If one were studying the comparative soluble salt content of the above 

 list of soils and obtained the foregoing depressions of the freezing point
