Harry, I can't thank you enough for this.  I've searched years
for this issue with no luck!  For me, this is the greatest
article Tesla has ever written.  A rare look at "Tesla's Tesla Coils"

Special Note:
The Turn Of The Century Electrotherapy Museum is honoured to
present three rare works on Lichtenberg Figures made by Danish
Scientist P. O. Pedersen.  We have obtained permission to publish
these papers from The Danish Royal Academy, who graciously sent
us uncut originals from 1919, 1922, and 1929.  These volumes are
at the museum, with PDF versions below.

We are grateful for the assistance of Danish Tesla Coiler Finn Hammer,
who has created many masterpiece Tesla Coils that included homemade
transformers and variacs that look better than those which can be
purchased new.  His amazing website is located at:

Thank You Finn, for giving us the opportunity to see and share these
wonderful documents.
