That's true, that's one of the obsolete ones. Or rather, it is a useful
shortcut, treat a macroscopically homogeneous medium such as the
dielectric of a capacitor as homogeneous rather than dealing with every
single atom, electron etc. individually.

Of course, what we know as "Maxwell's Equations" have been heavily 
modified by Heaviside and others.

Maxwell knew of, or should have known of, Fizeau's work showing the speed
of light is not relative to the medium for small values of (n-1) with n
being the index of refraction. Instead it approaches c as a limit for n
near 1.
