Thanks, David.
I'm clearly having an unclear day -- actually felt dizzy yesterday and took
off sick for the afternoon; something flu-like is going around the office.
Concerning ordinal names etc., David is utterly right as usual (told you he
was a bad one to challenge!) and I think I'll retire from the discourse till
after the weekend. Carry on.
