the book is right, you are wrong - corona and leader are far not the
same, even corona and streamer are far not the same.

it`s positive discharge, so this experement once more proves the facts

there are several very logical reasons - they`re all described in the
book. in the other book ("Physics of lightning and of lightning
protection", page 91) it`s written, that everything this was proved by
the experiments and there`re some data from the experiments.
