  The author describes some stones which he found at the bottom of Khushmo
River's shoal during 1988 expedition into the region of the Tunguska impact
(1908). Photos of stones are presented. Three stones have traces of melting and
the author consider these stones as probable Tunguska meteorites. Some
arguments are presented to confirm author's opinion. Results of investigation
of prospect holes in peat-bogs are briefly described too. New data concerning
heat impulse of the Tunguska impact are obtained. There is the assumption that
some meteorites which are formed during comet impact looks like stony or
glass-like thin plates with traces of melting.
