Ah Schiehallion. Theres a name to bring back memories. I once lost a camera
up there when I was 13, on the final day of a holiday...

It was from observations of Schiehallion that Maskelyne measured the
mass of the earth .....erm don't ask me how!

Hey, I remember my Grandpa telling me about this!

It was something to do with the fact that Schiehallion is a very symetrical
mountain and consistent gravity measurements could be made around it.

OK, I'm intrigued now and just Googled it:
