By means of the measured values Here as well as later on the value given above [eqn:(79)] (79) has been replaced by $a=7.39·{10}^{-}15$, obtained from$ = ac4 = 5.54 · 10^-5$. This is the final result of the newest measurements made by W. Westphal, according to information kindly furnished by him and Mr. H. Rubens. (Nov., 1912). [Compare [page:64]p. page:64, footnote. Tr.] of $a$ and $c_2$ the universal constants $h$ and $k$ may be readily calculated. For it follows from equations [eqn:(277)] (277) and [eqn:(288)] (288) that $h=\frac{a{c}_2^4}{48\pi \alpha c}k=\frac{a{c}_2^3}{48\pi \alpha }.\mathrm{\backslash Label}[eqn](292)\text{upshape (292)}$ Substituting the values of the constants $a$, $c_2$, $\alpha$, $c$, we get $h=6.415·{10}^{-27}\text{erg}\text{sec}.,k=1.34·{10}^{-16}\frac{\text{erg}}{\text{degree}}.\mathrm{\backslash Label}[eqn](293)\text{upshape (293)}$
