  As we showed in a preceding arXiv:gr-qc Einstein equations, conveniently
written, provide the more orthodox and simple description of cosmological
models with a time dependent speed of light $c$. We derive here the concomitant
dependence of the electric permittivity $\epsilon$, the magnetic permeability
$\mu$, the unit of charge $e$, Plank's constant $h$, under the assumption of
the constancy of the fine structure constant $\alpha$, and the masses of
elementary particles $m$. As a consequence of these concomitant dependences on
time they remain constant their ratios $e/m$ as well as their Compton wave
length $\lambda_c$ and their classical radius $r_0$.
