Very nice, Philippe, un tout grand merci!
It is only 77 double pages, not that big a volume, but it is a rather
poor scan of a not too brilliant print so it takes some deciphering
especially in the formulae. I'm afraid it's going to give me a hard
time; but it does bring the info I am after.

Stealth, allow me to be nasty: what is a translation worth to you? And
don't come and offer me a crate or even a barrel of your lousy
Australian beer!
