Thanks for the kind thoughts on and off line about Poll. She's still hanging on in there, which shouldn't come as a surprise given her rocky start to life and the determination she showed then. Between you and me, I think she knows the world exists purely for her benefit and is loathe to see it end abruptly when she goes, leaving us all in limbo. Of course she's right, but don't tell her I said so... ;-)
Anyway, yes, 'tis the hanging sheep of I & H Sorby that I had in mind. A bijou example ici:can search the PDF - I am, of course, a div. It's happening an awful lot just recently. Mind you, it shouldn't come as a surprise; one brain cell is easy to lose... And also a thank you to Gary for the excellent laugh I had from the quip that "I Sorby" was a Roman emperor. "I came, I Sorby, I made tools" perhaps?
