Small Fires and Escaped Apostrophes

I should have been at the Proms tonight, but we were turned away from the door being told that a "small fire" had left the Royal Albert Hall with no power. Bummer! I'd been looking forward to an evening of Beethoven's Ninth. Still - it's one of the regular components of the Proms season so we shall try again next year.
All that said, the day wasn't a complete wash-out. SB and I had decided to have a mooch around the South Ken. museums for a few hours ahead of the concert. I'd forgotten just what a pleasant courtyard the V&A has. We spent a while there with a coffee, people watching in the late-summer sun.
We also braved the hoards of screaming kids at the Natural History Museum (it being a weekend and school holidays) where this little gem was discovered outside the escalator up to the whizily-interactive Earth Galleries. Note that an escaped apostrophe can even make an appearance here! If you look closely, you can see that someone has tried to cross it out (no it wasn't me).
I remember visiting the old Geological Museum as a kid and finding a very dry set of rocks in cases. I think I was about 7 or 8 at the time and so after seeing the huge dinosaur skeletons elsewhere in the building I was rather underwhelmed. It's the first time since then that I have made it round the corner from the familiar teracotta edifice on Cromwell Road, to this part of the museum. As its redevelopment was completed in 1988 I can't really call it new but it certainly makes a difference. I'd recommend taking a look. There's lots to see and press and light up - all very tactile. I suppose rocks are rather less fragile than many museum exhibits.
