We comment on the structure of intersecting black p-brane solutions in
string theory explaining how known solutions can be obtained from Sch
warzschild solution simply by sequences of boosts and dualities, This
implies, in particular, that dimensional reduction in all internal wor
ld-volume directions including time leads to a metric (related by anal
ytic continuation to a cosmological metric) which does not depend on p
-brane charges, i.e. is the same as the metric following by reduction
from a higher-dimensional 'neutral' Schwarzschild black hole.
