*squeak*

Dear xxxx

I didn't have time to say on Monday that your student was very
impressive. Lots of good stuff in the thesis, and when we did give her
tough questions (like the scintillator that emitted Cherenkov
radiation) she responded in a very positive and physicist-like way. I
was sorry George took the Graduate School instructions about not
informing the candidate at their face value: she deserved to be told
on the spot that she'd passed with flying colours.

Best wishes
