Abstract
SINCE we proposed a graphical procedure to estimate the solid volume percentage below detectable size1, an alternative method has been suggested by Eckhoff2. Using our data1, he obtained two values for the solid volume, V ∞, which are about 5 per cent below our estimate. The purpose of this communication is to discuss the reasons for these differences. The numerical differences arise through different extrapolation criteria; thus values similar to Eckhoff's can be obtained from our method with his criteria. Our value, however, cannot be found from Eckhoff's method. This is not a criticism; his method was not intended for use with an equation.
