See if you can find it - "A Chart Atlas of Complex Hyperbolic

Hi Reg,

A rare citation indeed, following an equally rare citation (Kennelly
following Smith, that is, and rare meaning a citation offered by you
who usually claim such activity reveals plagiarism).

But as for your challenge (yes a heated term I suppose - but
still...):
Google "Complex Hyperbolic Functions" Kennelly
to find from:
http://www.geocities.com/neveyaakov/.../kennelly.html
"Arthur Edwin Kennelly was U.S. electrical engineer who made
innovations in analytic methods in electronics, particularly the
definitive application of complex-number theory to
alternating-current (ac) circuits."

Let me quickly add that Kennelly was US through immigration and
professional employment, but British schooled and trained.

Such an introduction would put your comment to the test:
The Victorian multi-dimensional charts remained in use through the
days of VLF and LF radio and for 5 decades until the advent of
computers.

Which on one hand would suggest rather Edwardian than Victorian, and
on the other hand, perhaps Wilsonian for where this tome was actually
published.

I have a copy of Kennelly's "A Chart Atlas of Complex Hyperbolic
Functions", in my library in Florida. I'd be pleased to scan it for anyone who'd
like a copy, but only if you have the patience to wait until I return south in
November.
