Re: cathode rays - historical question

The debate in the latter part of the 19th century about the nature of

continuous fluid (bearing in mind that the atomic theory was not fully
accepted by the physics community in that period),

All of the above. I suspect you could have found the
answer yourself:

It is helpful but not even 100% necessary to
spell it "Thomson".

Not true. To quote from the first site returned from google:
http://www.aip.org/history/electron/jjrays.htm

Maybe cathode rays were
similar to light waves? Another
possibility was that cathode rays
were some kind of material particle.
Yet many physicists, including
J.J. Thomson, thought that all
material particles themselves might
be some kind of structures built
out of ether, so these views were
not so far apart.
