  An established procedure for the estimation of ice-water interfacial energy
based on evaluation of the slope of the experimental ice nucleation rate data
versus scaled temperature is critically analyzed in this work. An inconsistent
estimate of the ice-water interfacial energy is found in the work of Murray et
al. [Phys. Chem. Chem. Phys., 2010, 12, 10380-10387]. The source of the
inconsistency is identified in an inappropriate regression method used for
experimental ice nucleation data fitting, a correct estimate of the ice-water
interfacial energy is presented, and limits of the slope method are discussed.
