  Some coworkers of mine here 
are casually looking for the oldest references that describe the 
phenomena reported in this paper."


Jim:

    Have them try getting "Electrical Radiation" by Oliver Lodge, 
Philosophical Magazine, June 1889; I believe it describes his 
experiments with coupling between two resonant circuits using Leyden 
jars.  I got this reference from "Syntony and Spark, The Origins of 
Radio" by Hugh Aitken, Wiley-Interscience and there are other good 
references there.  If you haven't seen it (I'll bet the Caltech library 
has a copy) tuning or "syntony" is the whole theme of the book.  I would 
also looking at  Zenneck and Seeling, "Wireless Telegraphy", English 
translation by McGraw Hill of a 1906 book in German.  Chapters IV 
"Coupled Circuits" and V "Resonance Curves" have lots of design 
equations and references to published articles which are probably prior 
to 1906.  Specifically derives the coupling constnat "k" with which we 
are all familiar

    I wonder if there's anything in Maxwell which is worth looking at?
