I really don't know what rules you are talking about.

Hello.
I'm trying to find something about Vaschy's rules (in electrotechnics,
electric circuits). Can you tell me something about them?
I assume he means the mathematical physicist Aimée Vaschy (1857-1899),
who contributed to the Thevenin and Norton circuit equivalence
theorems.

Hi Terry,
Your recollection is far better than mine.

And in fact I now suspect my conclusion was superficial. It seems he
suggested Thevenin was *wrong*, so Vaschy can hardly be called a
'contributor'. Here's a brief extract from my earlier source:
http://cmc.rice.edu/docs/docs/Joh2001Aug1Originsoft.pdf:
"The year 1883 marked publication of at least four papers [5],
[18]-[20] in Annales Télégraphiques, the second of which [5] described
what he thought was his new equivalent circuit result. Excited by his
result, Thévenin wanted to report it to the French Academy of
Sciences. According to Suchet, Thévenin asked a colleague, the
mathematical physicist Aimée Vaschy (1857-1899), to comment on the
paper. Vaschy thought the result incorrect. Thévenin consulted others,
and varied opinions were offered. Eventually his previously published
paper [5] was published virtually verbatim1 in Compte Rendu in the
same year."
A more thorough search turns up more work by Vaschy that I think more
relevant.
If the OP is still interested, here are a few more links:
http://arxiv.org/PS_cache/physics/pdf/0309/0309040.pdf
http://www.esanet.it/chez_basilio/antenna.htm
http://ing.pub.ro/engleza/programa/sem3.htm
http://software.ucv.ro/Cursuri/Electrical_engineering2/electrical_engineering2.html
Those last two make explicit reference to 'Vaschy Theorem', as part of
circuit network theory. The most I could find was that it is 'The null
action sources theorems'. But nowhere could I find what the actual
theorems *are*.
