  A new measurement of the branching ratio, $R_{e/\mu} =\Gamma (\pi^+
\rightarrow \mbox{e}^+ \nu + \pi^+ \rightarrow \mbox{e}^+ \nu \gamma)/ \Gamma
(\pi^+ \rightarrow \mu^+ \nu + \pi^+ \rightarrow \mu^+ \nu \gamma)$, resulted
in $R_{e/\mu}^{exp} = (1.2344 \pm 0.0023 (stat) \pm 0.0019 (syst)) \times
10^{-4}$. This is in agreement with the standard model prediction and improves
the test of electron-muon universality to the level of 0.1 %.
