Abstract Errors are discovered in the authors' calculated excess enthalpies based on the Buchowski-Ksiazcyak λh equation. The authors inadvertently subtracted the solute's enthalpy of fusion from the product universal gas constant (in Joules/(mole K)) times Buchowski-Ksiazcyak h parameter, without changing the units of solute's enthalpy of fusion to Joules/mole. As a result all of the 81 excess enthalpies given in Table 8 of the published paper by Huang and coworkers are in error.
