Abstract
This commentary shows that the dimensionless thermal slip parameter (β *2 ) and the dimensionless concentration slip parameter (β *3 ) are dimensional. Appropriate correct forms of β *2 and β *3 are given. Also, the second elasticity parameter (E2) is dimensional. An appropriate correct form of E2 is given.
