  We present the explicit form for all the four dimensional, static,
spherically symmetric solutions in $(4+n)$-d Abelian Kaluza-Klein theory by
performing a subset of $SO(2,n)$ transformations corresponding to four
$SO(1,1)$ boosts on the Schwarzschild solution, supplemented by $SO(n)/SO(n-2)$
transformations. The solutions are parameterized by the mass $M$, Taub-Nut
charge $a$, $n$ electric $\vec{\cal Q}$ and $n$ magnetic $\vec{\cal P}$
charges. Non-extreme black holes (with zero Taub-NUT charge) have either the
Reissner-Nordstr\" om or Schwarzschild global space-time. Supersymmetric
extreme black holes have a null or naked singularity, while non-supersymmetric
extreme ones have a global space-time of extreme Reissner-Nordstr\" om black
holes.
