Nora,

You got me on the book, I just don't remember a British book from 1975 with
that information.  Please understand that doesn't mean a thing about its
existance.  As my wife will immediately agree, my memory isn't my best
characteristic/trait/strength -- and as the others aren't all that great, we
are in trouble.  I'll dig around in the bookcase tomorrow and see if by
happen-chance something turns up.
