Pierre,

This version looks very good. I have attached comments, and one area that does not read quite right. With these corrected, we should be complete.

I looked at the LI draft. I need to review it in more detail, and I have a few questions about the mechanics of LI that you mentioned in your preface.

I am pleased with our progress on this project.

Regards,

John L.
