It is the primary mission of the present article to show that the premises and method in the articles of Chao et al. (1982) and Bertin and Ozoe (1986) (in the following referred to as CCO and BO, respectively) are flawed because indiscriminate extrapolation is not permissible for low Prandtl numbers and that there is no corroborative experimental evidence for Pr number influence on the onset of convection. The question is posed in order to accentuate the lack of response in the literature following the publication of CCO and BO.
