 of the curve equally well. However, from the values for $$\beta$$ one can easily see, that 's theory requires totally different velocities, than the one of or. For these two theories, the velocities are nearly identical, and what is even more remarkable: The function $$\Phi(\beta)$$ numerically agrees, as one can easily convince himself, with both of them (within the velocity interval given here) with a deviation of at most 2%.

The decision thus only depends on equations (19) and (22) or (20) and (23).

The values of the field integrals, calculated in the appendix p. 543ff, are:

Thus

$E/Mc=0,1884.\,$

On the other hand, the calculation by means of the curve constants (under consideration of the corrections due to the error of the $$z$$-scale mentioned on p. 513):

The values for $$\epsilon/\mu_0$$ are

Eventually one can also make a comparison of the different theories, by determining the constants A and B, or C and D themselves, from equations (16) be means of the measured values of M and E and the
