Thanks to all those who have replied. Here are some more corrections.

Thanks to everyone who spotted the reference to "notrix". It is left
as an exercise to the reader to figure out the correction :-)

In Question [4] there are some extra lines:

> Subject: nitrox I is 40 msw (130 fsw). At this depth the PO2 is 1.6 ATA
>	(see

This and the blank lines should be removed. This isn't in my original,
I guess I must have clicked the wrong mouse button at the wrong time :-)

As you may have noticed this question didn't really follow the numbering
system. I put this in just before I sent the message. I left it very terse
to judge the reaction to it. Many books just ignore this issue and some
even confuse it by talking about nitrox32 on one page to mean 32% O2
and nitrox90 meaning 90% N2 on another.

The following was suggested as an addition/correction:

> Note also that in EANx, x refers to the percentage of oxygen, e.g.
> EAN/32 = nitrox68 = NOAA Nitrox I
> EAN/36 = nitrox64 = NOAA Nitrox II

I will add this to the original. I could also add a comment about ONM
(oxygen-nitrogen mixtures), which also quotes the O2 percentage first;
ie ONM32 = nitrox I. Or would this just confuse things?

One thing I would like is more feedback from those who have no experience
of nitrox. Which bits are confusing? Where is the information too detailed
or not detailed enough? Feel free to email me direct, as many have, if
you don't feel comfortable about posting to the list.

Alan
