Comments are given to show that for calculating the composition derivative of the mother thermodynamic quantity in obtaining the partial molar quantity, the curve-fitting of the mother function followed by arithmetic differentiation of the resulting function is often dangerous. An example is provided. (C) 2012 Elsevier B.V. All rights reserved.
