Thank you very much.
We have now ended this. I just want to thank Dr. Blackstock very much for coming and for giving us, as Madame Demers said, probably the single most interesting and definitive set of presentations of the problems and the solutions that we've had to date. Thank you again.
I'm going to end this session so that we can wait for the other session to begin. That gives us about a minute.
Thank you.
