OK, I give up.
First, I guess there's plenty of info in the archive but I'm stuck at
getting it.  So, if anyone out there can give me the exact
name/reference of a suitable in-vitro medium for CP's, I'd appreciate
it.  If the reference can include a Sigma Chemicals or Aldrich reference
number that would be brilliant. 
My good friend Isao told me to use 1/5 MS Media but I'm having trouble
getting a supply using this reference.  Can anyone expand on this? 
While we're at it, I tried mailing the server with the following two
commands to try to find archive info on in-vitro media for CP's:
	First I sent to: listserv@opus.hpl.hp.com   
			 with no subject and text of "index cp"
	Then I tried to: listproc@opus.hpl.hp.com 
			 with no subject and text of "index cp"
		(in both cases I did not include quote marks)
Problem was no reply to either mail.  Is the server slow or did I do
something wrong?  Both instructions were taken from earlier help mails.
Regards
Paul (just starting out on in-vitro)
