Blackheath, Hampstead and Richmond Scientific Societies - are there others?

I know of the Blackheath Scientific Society, the Hampstead Scientific Society and the Richmond Scientific Society. They all put on evening talks, generally once a month, in what I think many would agree are lovely parts of town - there must be more scientific societies like this in London? I don't mean societies for professional bodies but more for local enjoyment of science, or pleasant disagreement depending on the talk under discussion.
